[0039] While the above-identified drawings set forth presently disclosed embodiments, other embodiments are also contemplated, as noted in the discussion. This disclosure presents illustrative embodiments by way of representation and not limitation. Numerous other modifications and embodiments can be devised by those skilled in the art which fall yvithin the scope and spirit of the principles of the presently disclosed embodiments.DETAILED DESCRIPTION

[0040] In particular, the systems and methods described herein are provided to increase the visibility of riders while operating personal transportation devices using a system of lights.

[0041] In some embodiments, personal transportation devices include scooters, bikes, skateboards, segways, and one-wheels, among other similar devices. In some embodiments, personal transportation devices can have one or more electronic components that, for example, assist the rider in moving the transportation device (e.g., a scooter with an electric power supply, or an ‘‘electric scooter’’).

[0042] In some embodiments, as shown in FIG. 1, an illumination system (100) can be used on a scooter (or an electric scooter) (101). In some embodiments, the illumination system includes a housing (107) that stores one or more components of the illumination system (100). The housing (107) can store an illumination source (110). a controller (130), a rear light (140), and a detector (160), among other components. In some embodiments, the housing (107) can Page 5 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 be attached to a fender (105) of a rear wheel (103) of the scooter (101). In some embodiments, a side light (170) is attached to the scooter (101).

[0043] As noted above, in some embodiments, the illumination system (100) contains an illumination source (110). The illumination source (110) can emit a light. The light emitted from the illumination source illuminates an area (the area is sometimes referred to herein as a “zone of light ' (120)). In some embodiments, and as described in greater detail below, the zone of light (120) can illuminate a rider of a personal transportation device (e.g., the scooter (101) of FIG. 1). In some embodiments, the illumination source (110) can include one or more light source(s). Suitable light sources include lasers, light bulbs, light emitting diodes (“LED”), or any other device that emits light. In some embodiments, the light source emits a light that is emitted out of the illumination source (110). In some embodiments, light from a light source can pass through one or more light manipulating devices. Suitable light manipulating devices include dispersion lenses (e.g., diffractive beam splitter lenses, aspheric lenses, focusing lenses, etc.), mirrors, diffusers, prisms, metasurfaces, glass panes, and other light permeable or semi-permeable lenses.

[0044] In some embodiments, the light manipulating devices can change one or more of the direction, focus point, shape, color, brightness, frequency (e.g., flashing of the light), or pattern of the light emitted from the light source. In some embodiments, the brightness of the light can be controlled by supplying various amounts of power to a light source. In some embodiments, the amount of power supplied to a light source can overdrive the light source. In some embodiments, overdriving the light source can increase the intensity of the light emitted from the light source. In some embodiments, overdriving the light source can cause a light source to emit more light than the light is graded to emit. In some embodiments, the light manipulating devices can be adjusted to control one or more aspects of the light (e.g., the direction, shape, color, pattern, etc.) that is emitted from the illumination source (110).

[0045] In some embodiments, the color of the light can be adjusted by controlling the light emitted from the illumination source (110). For example, the color of light emitted from an LED can be adjusted by varying the intensity of the red, green, and / or blue (e.g., RGB) light of the LED.

[0046] In some embodiments, the illumination source (110) can be configured to move within the housing (107). In some embodiments, the illumination source (110) can be in a position such that it can be completely surrounded by the housing, and light cannot be emitted from the illumination source (110) out of the housing (107). In some embodiments, and as illustrated in FIG. 1 , the illumination source can be in a position such that a portion of the illumination source Page 6 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 extends out of the housing, enabling a light to be emitted from the illumination source (110). In some embodiments, at least some of the housing (107) can be made of a transparent, translucent, or other light permeable or semi-permeable material (e.g., the housing (107) can comprise a lens). In some embodiments, the illumination source (110) can be aligned with the housing such that the portion of the illumination source that emits light can be directed towards a portion of the housing (107) that can be made of light permeable or semi-permeable material, such that when the illumination source (110) emits a light, (e.g., a zone of light (120)), the light can pass through the housing (107) through the light permeable or semi-permeable material (e.g., the lens). In some embodiments, a retractable lens cover can cover (e.g., protect the lens and prevent light from emitting from the lens) and / or clean the light permeable or semi-permeable material. In some embodiments, the retractable lens can be in a retracted configuration (e.g., uncover the lens) or a covered configuration (e.g., cover the lens). In some embodiments, a portion of the housing can be configured to move from a position where the housing is substantially continuous, i.e., the housing has no apparent breaks or gaps, to a position that has one or more breaks or gaps. In some embodiments, the illumination source can be configured such that it can emit light through a gap in the housing (107) when the housing contains a break or gap. In some embodiments, at least some of the illumination source (110) can be attached to the outside of the housing (107).

[0047] As noted above, in some embodiments, the illumination system (100) can contain a rear light (140). The rear light (140) can include a lens. In some embodiments, and as described in greater detail below, the rear light (140) can include a plurality of lights and a plurality of lenses.

[0048] In some embodiments, the housing (107) can be coupled to the personal transportation device (e.g., the scooter (101) of FIG. 1). In some embodiments, the housing (107) can be assembled prior to coupling the housing (107) to the personal transportation device. The housing (107) can be attached to the personal transportation device using any conventional coupling method, such as with screws, nails, adhesives, or any other manner that can couple the housing (107) directly or indirectly to the personal transportation device. In some embodiments, the location of the housing (107) on the personal transportation system (e.g., the scooter (101) of FIG. 1) can be adjusted. In some embodiments, the location of the housing (107) on the scooter (101) can be adjusted to alter the location of one or more lights (e.g., illumination source (110), rear light (140)).

[0049] As shown in FIG. 2, in some embodiments, the zone of light (120) can be emitted from the illumination source (110) such that the zone of light (120) covers at least a portion of a rider Page 7 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 (200) of a personal transportation device (e.g., the scooter (101) of FIG. 2), thereby illuminating the rider (200). In some embodiments, the area covered by the zone of light (120) can fully illuminate the back side of the rider (200). In some embodiments, the zone of light (120) illuminates only a portion of the rider (200). For example, in some embodiments, the outer boundaries (125) of the zone of light (120) can be adjusted to change the area covered by the zone of light (120). As shown in FIG. 2, the zone of light (120) covers from the back of the knee to the top of the head of the rider (200). In some embodiments, the zone of light can cover the entire body of the rider (200). In some embodiments, the rider (200) can be positioned on a deck (210) of the scooter (101). In some embodiments, and as shown in FIG. 2, the zone of light can be substantially rectangular in shape. In some embodiments, the zone of light (120) can be circular, ovular, or any other shape that can be emitted from the illumination source (HO).

[0050] In some embodiments, the rider (200) can be covered by the zone of light (120) regardless of the stance or position of the rider on the personal transportation device. The rider can be in various positions while riding a personal transportation device. For example, a rider of a scooter can be in a squatted position, a standing position, positioned with their feet pointed in the same direction as the direction of movement of the scooter, standing with their feet pointed in a different direction than the direction of movement of the scooter (e.g., substantially perpendicular to the direction of movement of the scooter), and standing with their feet adjacent one another, among other positions. Additionally, the rider can be closer to the front of the personal transportation device or closer to the back of the personal transportation device. However, in some embodiments, regardless of the position of the rider on the personal transportation device, the rider (200) can still be covered (i.e., illuminated) by the zone of light (120).

[0051] In some embodiments, the position of the rider on a personal transportation device can depend on the size of the personal transportation device and / or the amount of space the personal transportation device can allocate for a rider. For example, the position of a rider of a scooter, or e-scooter, can depend on the position of the scooter deck (e.g.. the scooter deck (210) of FIG. 2). In some embodiments, the zone of light (120) can be configured to illuminate the entire body of a rider regardless of the position of the rider on the personal transportation device (i.e., regardless of if they are squatting, standing with an arm extended in any direction, etc.). In some embodiments, the zone of light (120) can be configured to illuminate all the area where it is possible for any portion of the rider to be located while the rider is on the personal transportation device. In some embodiments, the area that any portion of a rider can be located Page 8 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 while on a personal transportation device can be referred to as the “possible rider location.” In some embodiments, the zone of light (120) can be configured to illuminate the entire possible rider location. In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 5 % larger than the possible rider location (i.e., the zone of light illuminates the entire possible rider location and extends at least 5% in one or more directions beyond the edge of the possible rider location). In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 10 % larger than the possible rider location. In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 20 % larger than the possible rider location. In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 30 % larger than the possible rider location. In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 40 % larger than the possible rider location. In some embodiments, the zone of light (120) can be configured to illuminate an area that is at least 50 % larger than the possible rider location. In some embodiments, adjusting the zone of light includes illuminating one or more additional lights of the illumination source. In some embodiments, the one or more additional lights of the illumination source can be positioned to illuminate a relatively higher or lower portion of the “possible rider location.”

[0052] In some embodiments, one or more lights (e.g., the rear light (140) and / or illumination source (110)) can increase the visibility of the rider (200). In some embodiments, a personal transportation device and a rider of a personal transportation device can be in a location near other vehicles (e.g., cars, other personal transportation devices, etc.) and / or obstacles (pedestrians, narrow streets / alleys, etc.). In some embodiments, the visibility of the personal transportation device can be important for the safety of the rider of the personal transportation device and other people in the area (e.g., other riders, pedestrians, etc.). In some embodiments, a personal transportation device can be more easily detectable for another object (e.g., an operator of a car, a pedestrian, etc.) when the other object is further away from the personal transportation device. However, in some embodiments, as the other object (e.g., a person, a car, etc.) is approaching the personal transportation device, the visibility of the personal transportation device can decrease. For example, when a car is further away from a personal transportation device, the view of a rear light of the personal transportation device can be readily observable in the field of view of the operator of the car, however, as the car approaches the personal transportation device, the rear light of the personal transportation device may be lower in the field of view, or may be outside of the field of view of the operator of the car. In some embodiments, a personal transportation device with additional lights (e.g., illumination Page 9 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 source (110)) or with lights that can attract more attention (e.g., by flashing, increasing brightness, changing color, etc.) an operator of a car may more easily see the personal transportation device and / or the rider of the personal transportation device, thereby increasing the safety of the personal transportation device.

[0053] In some embodiments, the light source comprises a laser. In some embodiments, the direction of the laser can be adjusted such that the laser is directed towards a reference point on the personal transportation device (e.g., the center of the handlebars of a scooter). In some embodiments, after the laser is directed towards the reference point, one or more light manipulated devices can be placed in front of the laser, causing the area covered by the laser to increase (e.g., create a larger zone of light). In some embodiments, the size and shape of the zone of light can be adjusted be altering the one or more light manipulating devices (e.g., changing the number of light manipulating devices, changing the type of light manipulating devices, changing the position of the light manipulating devices, etc.). In some embodiments, the zone of light can be adjusted by changing the direction of the laser (e.g., by changing the reference point on the personal transportation device). For example, if it is desired to make the zone of light cover an area that is closer to the ground, the reference point on the personal transportation device can be lowered, and the direction of the laser can be lowered.

[0054] In some embodiments, a system can have an illumination source that is positioned in front of the rider. For example, as shown in FIG. 4A, an illumination source (e.g., an illumination source stored in a housing (107)) can be positioned at the base of support bar (220) that connects the handlebars (230) to the personal transportation device. In some embodiments, the illumination system in front of the rider (200) can illuminate the front side of the rider (200). In some embodiments, and as shown in FIG. 4A, the illumination system can have an illumination source in front of the rider in addition to an illumination source behind the rider. In some embodiments, the system can have an illumination source in front of the rider instead of an illumination source behind the rider (i.e., the illumination source in front of the rider is the only illumination source). In some embodiments, the illumination system can have additional or alternative illumination sources in different locations. In some embodiments, and as shown in FIG. 4A, multiple illumination sources in an illumination system can emit light such that the zone of light from a first illumination source covers substantially the same area as a zone of light from one or more additional illumination sources. In some embodiments, multiple illumination sources in an illumination system can emit light such that the zone of light from a first illumination source covers a different area as a zone of light from one or more additional illumination sources.Page 10 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026

[0055] In some embodiments, an illumination source positioned in front of the rider can effectively provide a zone of light (120) to the front side of the rider (200). In some embodiments, the illumination source that is positioned in front of the rider can be such that the rider can more easily be seen from the front. In some embodiments, the illumination source from the front of the rider does not illuminate the head of the rider to avoid shining light in or near the eyes of the rider.

[0056] In some embodiments, the system can include a rider position detector. In some embodiments, the rider position detector detects the position of the rider relative to the personal transportation device. The rider position detector can include a camera, an infrared detecting system, or any other device that can determine the position of the rider. In some embodiments, the rider position detector can be in communication with the illumination system. In some embodiments, the rider position detector can provide rider position information to the illumination system. In some embodiments, the illumination system can adjust the zone of light based on the rider position information provided by the rider position detector. In some embodiments, the illumination system can move the zone of light to better align (e.g., cover more of the rider, center the zone of light with the center of the rider’s body, make the zone of light larger if the area of the rider is increased, etc.) the zone of light with the rider. In some embodiments, the rider position detector can detect the relative size (e.g., the dimensions) of the rider. In some embodiments, a rider can provide their dimensions (e.g., height, width, etc.) to the illumination system with, for example, the use of an input source. In some embodiments, the illumination system can adjust the zone of light (e.g., increase the size of the zone of light, move the zone of light to illuminate a taller and / or shorter person, etc.) and / or move the zone of light, based on the size of the rider.

[0057] As noted above, in some embodiments, the system contains a rear light. In some embodiments, the rear light contains a plurality of lights. For example, as shown in FIG. 3 A, FIG. 3B, FIG. 3C, and FIG. 3D, the rear light (140) can contain a plurality of lights (e.g., lights 301-304). In some embodiments the rear light (140) can contain at least 3 lights. In some embodiments, the rear light (140) can contain at least 5 lights. In some embodiments, the rear light (140) can contain at least 10 lights. In some embodiments, the rear light (140) can contain at least 20 lights. In some embodiments, the rear lights can include LEDS. As shown in FIG.3 A, in some embodiments the lights can have a circular shape. In some embodiments, the color of light emitted from each of the lights (301-304) can be adjusted. For example, in some embodiments, the rear lights can emit a red color light when the personal transportation device is slowing down or braking. In some embodiments, the rear lights can emit a white color light Page 11 of 23ACTIVE 719432992v1Attorney Docket No. 094 12-010701 / PCT Electronically filed: February 20. 2026 when the personal transportation device is moving in reverse.

[0058] As shown in FIG. 3B, FIG. 3C, and FIG. 3D, the light emitted from the rear lights can have different shapes. In some embodiments, the shape of the light emitted from the rear light can be controlled by the shape of the light or a casing surrounding the light. In some embodiments, the shape of the light emitted can be controlled by controlling the area in which light is emitted (e.g.. with the use of an LED). For example, as shown in FIG. 3B, the lights can emit an arrow pattern. The arrow pattern can indicate that the rider is turning. Additionally, the individual lights can be illuminated in a sequence. In some embodiments, all of the lights are illuminated at the same time and for the same duration. In some embodiments, a first light (301) is illuminated, then a second light (302) is illuminated, then a third light (303) is illuminated, and then a fourth light (304) is illuminated. In some embodiments, the plurality of lights are illuminated individually. In some embodiments, after a subsequent light is illuminated, a light that was previously illuminated remains illuminated. In some embodiments, after a subsequent light is illuminated, a light that was previously illuminated is no longer illuminated. In some embodiments, and as show n in FIG. 3D, the shape of a first light (e.g., light 301), can be different than the shape of a second light (e.g., light 303).

[0059] FIG. 3E shows a perspective view of a rear light (140) system having a plurality of lights (301-305). In the exemplary' embodiment shown in FIG. 3E, the plurality' of lights (301-305) are positioned on a light attachment (310). In some embodiments, the light attachment (310) can be curved and the plurality of lights (301-305) are positioned along the curved shape. The light attachment (310) can be attached to a personal transportation device. The plurality of lights (301-305) can emit light in a direction of light (330). In some embodiments, the direction of light (330) can be in the opposite direction as a direction of movement (320). A reference point (340) is also indicated in FIG. 3E.

[0060] FIG. 3F shows a similar rear light (140) system as FIG. 3E, however, in the example shown in FIG. 3F, the direction of movement (320) and the direction of light (330) are changed relative to the reference point (340). In some embodiments, FIG. 3F can show' a view' of a personal transportation device as the personal transportation device is turning. As can be seen by comparing FIG. 3E and FIG. 3F, the reference point (340) perceives light (e.g., from the various directions of light (330)) at a different angle. In some embodiments, the change in the direction of light is easier to perceive from the reference point (340) because of the curved shape of the plurality of lights (301-305). In some embodiments, and as show n in FIG. 3F, the reference point (340) can only perceive (e.g., view) some of the lights (301-305) or can have a worse perspective on some of the lights (301-305) (e.g., the reference point (340) can not Page 12 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 perceive and / or see light from light (305)). In some embodiments, because of the view of the reference point (340) on the lights (301-305) it is easier, at the reference point (340), to discern the direction of movement of the personal transportation device. For example, in some embodiments, a person standing at the reference point (340) can determine the direction of movement of the personal transportation device (e.g., if the personal transportation device is turning) based on the rear lights (e g., if the person can see all of the lights, if the view of some or all of the lights is partially or totally obstructed, etc.). In some embodiments, it can be easier for a person standing at the reference point to determine the direction of movement of the personal transportation device because of the shape of the lights (e.g., the shape of the light attachment (310)).

[0061] FIG. 4B shows a rear light (140) containing a plurality of lights (301-305) attached to a light attachment (310). As shown in FIG. 4B, the light attachment (310) can be connected to the rear wheel (103) of a personal transportation device (e.g., a scooter (101)). In some embodiments, the light attachment can be connected to a rear wheel fender or a portion of the deck (210) of the scooter (101). The scooter deck (210) can also connect to a support bar (220). As shown in FIG. 4B and as noted above, the light attachment (310) can be curved.

[0062] In some embodiments, the detector (e.g., a detector (160) of FIG. 1) or a plurality of detectors, can detect a change in one or more operating conditions related to the personal transportation device, including position, direction, speed, or other elements of the personal transportation device. Exemplary detectors, or sensors, include accelerometers, gyroscopes, inertial measurement units (“IMU”), global positioning systems (“GPS”), inertial navigation systems (“INS”), magnetometers, potentiometers, compasses, hall effect sensors, LIDAR, RADAR, ultrasonic sensors, tachometers, seismometers, proximity sensor, and other detectors that can detect changes in the personal transportation device. In some embodiments, the detectors, or sensors, can be configured to communicate changes detected in the operating conditions of the personal transportation device with the controller (130). In some embodiments, the controller (130) can be configured to utilize the information from the detectors to control the illumination system. For example, the controller (130) can control the one or more light sources of the illumination system (e.g., illumination system (100) of FIG.1) to illuminate the personal transportation device and / or the rider of the personal transportation device depending on the information communication from the detectors.

[0063] In some embodiments, the system can be configured such that a detector can detect an operation condition (e.g., a speed, a position, a direction) or a change in an operation condition (e.g., a change in speed, a change in direction, change in position) of the personal transportation Page 13 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 device. In some embodiments, the detector is attached to the personal transportation device in a manner such that it can detect the change in the operating condition (e.g., position, speed, direction) of an element of the personal transportation device that indicates that the personal transportation device is turning. For example, a detector can be placed near the handlebars of a scooter and can detect when the handlebars are rotated, indicating that the personal transportation device is turning. In some embodiments, the detector is a proximity sensor. In some examples, the proximity sensor can be configured to detect when a rider actuates a brake (e.g., a handlebar brake). In some embodiments, a proximity sensor can detect when a handlebar brake lever moves closer to the handlebar (e.g., when the rider pulls the lever closer to the handlebar to brake). In some embodiments, the proximity sensor can detect when a brake line moves while a personal transportation device is braking (e.g.. after a rider actuates a brake on a handle, the proximity sensor can detect a change in position in the cable that connects the brake on the handle to the braking system on the wheel).

[0064] FIG. 12A, FIG. 12B, and FIG. 12C show exemplary' schematic diagrams showing the operation of various proximity sensors. FIG. 12A shows a schematic diagram of an inductive proximity sensor. In some embodiments, a inductive proximity sensor can operate by detecting a position of two or more coils (e.g., coils 403 and 405). FIG. 12B shows a schematic diagram of a capacitance proximity' sensor. In some embodiments, a capacitance proximity' sensor can operate by detecting the position of two or more capacitance plates (e.g., capacitance plates 413 and 415). FIG. 12C shows a schematic diagram of a magnetic proximity sensor. In some embodiments, a magnetic proximity sensor can operate by altering a circuit because of a change in a magnetic field.

[0065] As noted above the detector can be in communication with other devices in the system. In some embodiments, the detector can be in communication with one or more light systems (e.g., one or more illumination system(s), the rear light(s), the side light(s), etc.). In some embodiments, there are one or more other devices (e.g., a controller, wiring, processors, etc.) that are disposed between the detector and the one or more light systems. In some embodiments, the one or more light systems can alter the light that is emitted from the light system based on information received from the detector.

[0066] For example, in some embodiments, a detector can detect a decrease in velocity for a personal transportation device and communicate the decrease in velocity' to one or more light systems. The one or more light systems can then change the color, brightness, pattern, or other element of the light that is emitted (e.g., can change the light to a red color, increase the brightness, and begin flickering / flashing the light in response to receiving information that the Page 14 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 personal transportation device is slowing down).

[0067] In some embodiments, a rider actuated indicator can be attached to the personal transportation device. The rider actuated indicator can allow a rider to indicate that they are going to turn. In some embodiments, the rider actuated indicator can be attached at the handlebars of the personal transportation device. In some embodiments, the rider actuated indicator can be attached near the base of the personal transportation device (e.g.. near the feet of the rider). In some embodiments, the rider actuated indicator can be in communication with one or more light systems. In some embodiments, when a rider actuates the rider actuated indicator, the rider actuated indicator communicates with the one or more light systems to illuminate a light in a predetermined manner. In some embodiments, the rider actuates the rider actuated indicator prior or concomitantly to turning the personal transportation device. In some embodiments, and as described in greater detail below, one or more illumination devices can emit a light in a manner that indicates the rider is turning or that indicates the rider is about to turn. In some embodiments, the rider actuated indicator can be configured to communicate with the controller (130) to allow the controller to utilize the information from the rider actuated indicator to control the illumination system. For example, the controller can use the information from the rider actuated indicator in conjunction with information from one or more detectors related to the direction of the personal transportation device to properly illuminate the personal transportation device and / or the rider of the personal transportation device.

[0068] In some embodiments, as shown in FIG. 5A, FIG. 5B, and FIG. 5C. the illumination system can illuminate a predetermined design on the back of a rider. For example, in FIG. 5 A, FIG. 5B, and FIG. 5C, if a rider indicates that they are going to turn with a rider actuated indicator or if a detector detects that a rider is turning, the illumination system can vary the zone of light to indicate that the rider is turning. As seen in FIG. 5A, FIG. 5B, and FIG. 5C, the zone of light can cycle through multiple illumination patterns (e.g., from FIG. 5A to FIG 5B to FIG. 5C) to indicate that the rider is going to turn or is turning. The illumination pattern can include varying the brightness, color, pattern, shape, direction, or other aspects of the zone of lights. As shown in FIG. 6A. FIG. 6B. FIG. 6C. and FIG. 6D, a similar process can occur when the rider is braking, or the rider otherwise indicates that they are braking.

[0069] In some embodiments, the light system can be in communication with an ambient light detector. The ambient light detector can detect the ambient light near the personal transportation device (e.g., can detect how bright it is outside). Suitable ambient light detectors include photodiodes. In some embodiments, the ambient light detector detects the brightness of the area surrounding the personal transportation device and communicates the ambient light Page 15 of 23ACTIVE 719432992v1Atorney Docket No. 094512-010701 / PCT Electronically filed: February 20. 2026 information, directly or indirectly, with an illumination source. The illumination source can adjust the amount of light emitted based at least in part on the ambient light information. In some examples, when there is relatively more ambient light, the illumination source emits more light (e.g., the illumination source increases the brightness of the light). In some embodiments, where there is relatively less ambient light, the illumination source emits less light (e.g., the illumination source decreases the brightness of the light). In some embodiments, when there is relatively more ambient light, to increase the brightness of the illumination source, excess power is supplied to the light system to increase the brightness of the light (e.g., the power overdrives the light source). In some embodiments, the ambient light detector can be configured to communicate with the controller (130) to allow the controller to utilize the information from the ambient light detectors to control the illumination system.
