In certain vehicles such as trucks, it is common to have three or more back lamps and / or stop / tail / turn lamps in order to provide brighter illumination.

Summary of the Invention

Means for Solving the Problems

[0003] Various embodiments of combination lamps are provided, which can combine a plurality of different lamp functions in an integrated configuration, simplify installation, and reduce the total amount of space occupied to generate at least substantially the same amount of illumination. The combination lamps can be configured for use in vehicles, lighting fixtures, self-standing lamps, decorative items, and the like. In some embodiments, each lamp component can have a power connection element independent of other lamp components.

[0004] In some embodiments, a combination lamp is provided that includes a stop / turn / tail lamp surrounded by a flange for mounting to a vehicle, and the stop / turn / tail lamp and the flange each have a separate set of light sources, preferably consisting of one or more light-emitting diodes (LEDs). At least a first portion of the LEDs in the flange are activated when the vehicle is reversing and thus function as a reverse lamp. In some embodiments, the stop / tail / turn lamp and the reverse lamp have separate power plugs connected to the vehicle, and the stop / tail / turn lamp illuminates when the driver signals, applies the brakes, or the headlights are on, and the reverse lamp illuminates when the vehicle is reversing, but not the other way around.

[0005] In some embodiments, at least a second portion of the flange LEDs may have a dedicated warning lamp function. The warning lamp can be activated and operated by a separate set of wires connected to a dedicated switch (on / off). When the warning lamp is in use and the user decides to put the vehicle into reverse, brake (stop), or turn mode, the built-in circuit can automatically interrupt the warning function so that the intense illumination of the warning lamp does not obstruct the visibility of the lamps used for the reverse, stop, and turn functions.

[0006] In some embodiments, a work lamp function can be incorporated in addition to or instead of a warning lamp. For example, the flange LED used for the reverse function can be a high-power LED, and the high power used for the work lamp function can be activated and operated by a set of wires connected to a dedicated switch (on / off).

[0008] In some embodiments, the first lamp is a stop / turn / tail lamp, and the second lamp is a reverse lamp.

[0009] In some embodiments, the second lamp is further configured to provide a white warning lamp function when a switch connected to a third power interface is turned on.

[0010] In some embodiments, a third lamp is further configured to provide an amber-colored turn light.

[0011] In some embodiments, the assembly is configured to be mounted on a vehicle.

[0012] In some embodiments, the flange includes multiple holes, and the assembly is configured to be attached to a vehicle through these holes.

[0014] In some embodiments, the assembly further comprises a connector wire connected to a switch, the connector wire configured to select a specific flashing pattern from a plurality of flashing patterns when the switch is turned on.

[0015] In some embodiments, the multiple flashing patterns consist of two-color flashing patterns and single-color flashing patterns.

[0016] In some embodiments, when a single-color flashing pattern is selected, the connector wire is further configured to switch to a different color.

[0017] In some embodiments, the present invention provides an assembly of an LED combination lamp, the assembly comprising: a first lamp located in the inner portion of the assembly and having one or more first LEDs and a first power interface; and a flange at least partially surrounding the first lamp and including one or more second LEDs and a second lamp having a second power interface connected to a switch, wherein the first lamp is a stop / turn / tail lamp, and the second lamp is a backup lamp and a work lamp, and the one or more second LEDs are high-power LEDs configured to provide work lamp functionality when the switch connected to the second power interface is turned on.

[0018] In some embodiments, the second lamp is configured to provide a light output of approximately 310 lm when operating as a backup lamp and approximately 1000 lm when operating as a work lamp.

[0019] In some embodiments, the assembly is configured to be mounted on a vehicle.

[0020] In some embodiments, the flange includes multiple holes, and the assembly is configured to be attached to a vehicle through these holes.

[0021] In some embodiments, the first and second lamps are connected to a common power source.

[0025] Specific exemplary embodiments of the present invention are described below with reference to the drawings. Generally, such embodiments relate to a combination lamp comprising at least two different sets of light sources, where each set of light sources can be operated independently of the other sets of light sources.

[0026] Referring to Figures 1 to 8, specific embodiments of the combination lamps 10 and 30 may comprise first lamps 100, 300 and second lamps 200, 400 that are fixed relative to one another. See, for example, U.S. Patent No. 8,052,313, the disclosure of which is incorporated herein by reference. While the combination lamp 10 shown in Figures 1 to 4 is substantially circular and the combination lamp 30 shown in Figures 5 to 8 is substantially elliptical, it should be understood that combination lamps configured according to the present invention may take any shape as a matter of application-specificity or design choice.

[0027] As shown in the figures, the first lamps 100, 300 may have a plurality of LEDs 101, 301 mounted on the first supports 102, 302, preferably covered by the first lenses 103, 303. The second lamps 200, 400 may have a plurality of LEDs 201, 401 mounted on the second supports 202, 402, preferably covered by the second lenses 203, 403. The first lamps 100, 300 and the second lamps 200, 400 may be constructed and arranged to be selectively removable from each other or permanently fixed, depending on the application or design choice. Preferably, the first supports 102, 302 are coupled to the second supports 202, 402 to fix the first lamps 100, 300 and the second lamps 200, 400 together. In addition, the second supports 202, 402 preferably include mounting elements 210, 410 for attaching the second lamps 200, 400 and preferably the combination lamps 10, 30 to a surface such as a vehicle.

[0028] Referring to Figures 1 to 4, depending on the specific application of the embodiments of the present invention, such as outdoor use, particularly on a vehicle, it may be preferable for the first support 102 to be permanently fixed to the second support 202 to provide safety. According to various embodiments of the present invention, the second lamp 200 can be directly mounted to a surface such as a vehicle body, and the first lamp 100 can be coupled to the second lamp 200, thereby allowing the first lamp 100 to be held in place. A particular exemplary embodiment includes a second lamp 200 having a flange for mounting to the rear of a vehicle. Thus, the second lamp 200 can be fixed to the vehicle, and the first lamp 100 can be coupled to the second lamp 200 by being inserted into a receiving opening of the second lamp 200, as a non-limiting example. According to a particular exemplary embodiment of the present invention, the first lamp 100 can be inserted into the receiving opening of the second lamp 200 until it is fitted into place, and thereafter the first lamp 100 cannot be removed.

[0029] Alternatively, as a non-limiting example, referring to Figure 2, it may be desirable that the first lamp 100 be detachable from the second lamp 200. Such detachability can facilitate the quick and easy replacement of the lamp 100 or its components. For example, the first lamp 100 can be removed from the second lamp 200, the necessary LEDs can be replaced, the electrical circuitry can be secured, the lens can be replaced, and other desired services can be performed, after which the first lamp 100 can be returned to its place. Alternatively, a replacement lamp can be installed while the first lamp 100 is being repaired. Although the first lamp 100 has been described as being inserted into and removed from the second lamp 200, it should be understood that the second lamp 200 can be inserted into or removed from the first lamp 100 without departing from the scope of the invention.

[0030] The use of LEDs has increased recently, due to their operating life of up to 100,000 hours before degradation begins. Therefore, LEDs generally have a longer operating life than standard high-brightness incandescent bulbs, which have a relatively short lifespan and are more susceptible to damage. Furthermore, LEDs are generally smaller than bulbs, offering greater flexibility in placement. Therefore, it may be preferable for a combination lamp 10 to consist of LEDs in both lamps 100 and 200. When used in a vehicle, the illumination provided by the LEDs preferably meets the appropriate DOT (Department of Transport) standards. For example, if the combination lamp 10 includes an amber LED lamp as the first lamp 100 and is used on the front of a vehicle, the amber LED lamp preferably meets the full-turn compliance standard. Preferably, the second lamp 200 meets the DRL (Daytime Running Light) standard and can be used as a DRL lamp, which the DOT recommends as enhancing safety by increasing the visibility and conspicuousness of the moving vehicle. However, if the second lamp 200 is used for other purposes, such as decoration, it does not need to meet the DRL standard.

[0031] Depending on the desired application of the combination lamp 10, the number and arrangement of LEDs for each lamp 100, 200 can be changed. For example, Figures 2 and 6 show a specific embodiment of combination lamps 10, 30 in which the first lamps 100, 300 have 9 LEDs and the second lamps 200, 400 have 18 LEDs, but it should be understood that the number of LEDs in each lamp can vary depending on the application or design choice.

[0032] According to embodiments shown in Figures 3 and 7, the first lamps 100, 300 are provided with a plurality of protrusions 104, 304 on the first lenses 103, 303 located above the LEDs 101, 301. These protrusions 104, 304 are preferably configured and arranged to disperse, for example, the light emitted from the LEDs below them by changing the direction of the emitted light. See, for example, U.S. Patents 8,009,364 and 8,717,679, whose entire disclosure is incorporated herein by reference. Figures 3 and 7 show second lamps 200, 400 without protrusions, but it should be understood that the second lamps 200, 400 may also include protrusions that are similar to or different from the protrusions 104, 304 of the first lamps 100, 300. The combination lamps 10, 30 may have any combination of lamps having protrusions, and the first lamps 100, 300 and the second lamps 200, 400 may have any number of protrusions without departing from the scope of the present invention.

[0033] According to various embodiments of the present invention, as shown in Figure 8, each lamp 300, 400 may have a specific power connection part 31, 32, such as a plug, socket, or some mechanism for connecting to a power source. The power connection parts 31, 32 may be connected to the same or separate power sources. Thus, each lamp 300, 400 can be turned on or off, or controlled independently in other ways. For example, if a combination lamp 30 as shown in Figures 5 to 8 is used in a vehicle, and the first lamp 300 is a stop / tail / turn lamp and the second lamp 400 is a reverse lamp, the first lamp 300 may be illuminated and the second lamp 400 may remain off when the driver of the vehicle signals or stops. On the other hand, when the driver is backing up, the first lamp 300 may remain off and the second lamp 400 may be illuminated. Alternatively, without departing from the scope of the present invention, the first lamp 300 may be a reverse lamp and the second lamp 400 may be a stop / tail / turn lamp.

[0034] When used in a vehicle, it may be preferable that each of the first lamp 300 and the second lamp 400 be connected to a power source via separate cables. For example, a vehicle may have two cords for each lamp opening or mounting section into which the combination lamps are installed. However, it is also possible to have one cord for each opening / mounting section, with the power from each cord being split by a distributor or similar component, the end of which is connected to either the first connection of the first lamp 300 or the second connection of the second lamp 400. This is particularly suitable for vehicles designed to accommodate only one lamp in each opening / mounting section.

[0035] One potential advantage of using the combination lamps according to embodiments of the present invention in vehicles (but not limited to, work trucks produced for use in wiring, piping, electric utilities, etc.) is that they can provide more light. For example, since the combination lamps 10, 30 occupy only one opening / mounting section, one conventional stop / tail / turn or reverse lamp occupies the upper rear of the vehicle, leaving one opening / mounting section free. One possible use of the freed opening / mounting section is to mount an additional combination lamp, thereby providing a total of four stop / tail / turn lamps and four reverse lamps (see, for example, Figures 9 and 10) while occupying the same space as two of each of the conventional lamps. Thus, the illumination provided for each operation such as braking, turning signals, and reversing can be doubled. Alternatively, conventional stop / tail / turn lamps or reverse lamps (or other types of lamps such as warning lamps or work lamps) can be mounted in combination with the combination lamps 10, 30, thereby providing additional lighting for specific operations.

[0036] Furthermore, it is preferable that the combination lamps 10, 30 are not significantly larger than conventional stop / tail / turn lamps or reverse lamps. For example, conventional lamps for vehicles, especially trucks, are generally mounted on a separate, dedicated mounting flange, which is then mounted on the vehicle. Alternatively, a separate, dedicated mounting flange can be mounted on the vehicle first, and then the lamp can be mounted on it. Another embodiment provides a lamp that is integrally formed with a dedicated mounting flange that is mounted on the vehicle. Thus, conventional lamps require both the lamp and the dedicated mounting flange structure. According to various embodiments of the present invention, the flange used for mounting can constitute one of the lamp components of the combination lamp. For example, referring to Figure 2, the second lamp 200 can constitute a flange that is mounted on the vehicle. Thus, in such embodiments, substantial structure is not added (the second lamp 200 occupies approximately the same space as the dedicated mounting flange used in conventional lamps), and space can be maximized.

[0037] According to embodiments of the present invention shown in Figures 1 to 8, the combination lamps 10, 30 preferably include at least two sets of light sources, one surrounding the other. As shown, the second lamps 200, 400 surround the outer periphery of the first lamps 100, 300. Such configurations are particularly useful for use as stop / tail / turn combination lamps in vehicles (see also Figures 13 to 16, which are described further below) or DRL-amber combination lamps, as a result of keeping the shape of the lighting consistent with standard stop / tail / turn, back, or amber lamps, and, more specifically, keeping the flange-lamp configuration consistent with conventional flanges and lamps, where applicable.

[0038] The first lamps 100, 300 and the second lamps 200, 400 of the combination lamps 10, 30 according to embodiments of the present invention that are not mounted on a vehicle may also be connected to a common power source via a distributor or separate cord. Alternatively, the first lamps 100, 300 and the second lamps 200, 400 may be connected to completely different power sources. Furthermore, the second lamps 200, 400 do not need to surround the first lamps 100, 300, and without departing from the scope of the present invention, they may be arranged side by side, intersect, or incorporated into a design, as these are application-specific or design choices.

[0039] Another potential application of embodiments of the present invention is a corridor, staircase, etc., where it may be preferable to provide one or more types of lighting. For example, dim lighting can be kept on at all times, and bright lighting can be turned on or off. According to a particular exemplary embodiment, second lamps 200, 400 can provide low-level, dim lighting such as night lighting and have a light sensor that turns on only when there is insufficient light present in the area. In contrast, first lamps 100, 300 can provide brighter lighting but are configured to be turned on or off by the user. By providing combination lamps, the same area can be used for two different types and sources of light.

[0040] LED combination lamps according to embodiments of the present invention can have various shapes and sizes, and can be used in various locations for various functions without departing from the scope of the present invention, as application-specific matters or design choices. In addition, without departing from the scope of the present invention, other modifications can be made, without departing from the scope of the present invention, as application-specific matters or design choices, such as changing the number of LEDs, the transparency of the lens, the shape and size of the support, the number, shape and / or size of protrusions, etc.

[0041] In various embodiments of the present invention, combination lamps 10, 30 can be provided that have substantially the appearance shown in Figures 1 to 8, but in which the LEDs 201, 401 within the flange are high-power LEDs (e.g., higher power and brightness compared to standard LEDs), and their stronger illumination can provide a separate third lamp function. For example, when the LEDs 201, 401 are embodied as high-power LEDs, they can provide not only a backup lamp function but also a work lamp function. The high-power LEDs can be activated and operated by a set of wiring connected to a dedicated switch (on / off). When the switch is in the "off" position, the LEDs 201, 401 can function as backup lamps providing typical backup lighting as described above. When the switch is in the "on" position, they become high-power, and the LEDs 201, 401 can function as work lamps providing brighter illumination at the rear of the vehicle. In some embodiments, the high-power LEDs 201, 401 can be mounted on an aluminum PCB, for example, to accommodate the increased heat generation.

[0042] In various other embodiments of the present invention, combination lamps 10, 30 can be provided that utilize different colors for different functions within the flange. Referring to Figures 11 and 12, for example, in various embodiments, combination lamps 10, 30 can be provided that incorporate emergency warning lamps 800, 900 into the flange. Figure 11 shows an exploded view of an exemplary circular combination lamp 10 having multiple functions, and Figure 12 shows a top view of an exemplary elliptical combination lamp 30 having multiple functions. The combination lamp in Figure 11 is similar to the combination lamps shown in Figures 1 to 4, and the combination lamp in Figure 12 is similar to the combination lamps shown in Figures 5 to 8, however, the combination lamps 10 and 30 shown in Figures 11 and 12 are configured to integrate at least three types of lamp components, with the first portion of the flange LEDs comprising LEDs 201 and 401 having one function (e.g., backlight), and the second portion of the flange LEDs comprising LEDs 801 and 901 having another function (and / or color) (e.g., a dedicated warning lamp function). LEDs 801 and 901 can be a different color (e.g., amber) from LEDs 201 and 401 (e.g., white) and distinguishable through the transparent lenses 203 and 403. LEDs 101 and 301 in the central region provide a third function (e.g., stop / tail / turn). LEDs 101 and 301 can be white, covered by a colored (e.g., red) lens, or colored (e.g., red) LEDs, covered by either a clear or colored (e.g., red) lens. Embodiments of combination lamps 10 and 30 shown in Figures 11 and 12 are shown with eight LEDs 801 and six LEDs 901, respectively, but different numbers and / or positions of LEDs 801 and 901 on the flange can be used for a second function of the flange, depending on the application or design choice. See also Figures 21 to 30 below.

[0043] Warning lamps 800, 900 can be activated and operated by a separate set of (dedicated) wiring connected to a dedicated switch (on / off). When warning lamps 800, 900 are in use and the user decides to put the vehicle into reverse, brake (stop), or turn mode, the built-in circuitry automatically interrupts the warning function so that the very bright illumination of the warning flashes does not obstruct the visibility of lamps 200, 400 used for the reverse function and / or lamps 100, 300 used for the stop / tail / turn function. In some embodiments, the amber (or other colored) warning lights are configured to flash unless the user chooses to introduce a switch for fixed illumination. In various embodiments, a separate set of wiring can activate the warning function. In some embodiments, if two or more combination lamps incorporating warning lamps are provided, auxiliary wiring can be used to repeat between different warning lamps. For example, when auxiliary wiring is connected, the user can synchronize the flashing of two or more warning lamps, such as flashing simultaneously, flashing alternately, or having different flashing patterns.

[0044] In various embodiments, although substantially having the appearance shown in Figures 11 and 12, combination lamps 10 and 30 can be provided that offer four functions (e.g., stop / turn / tail, reverse light, warning light, and work light) by incorporating work lamps into the flange. For example, the LEDs 201 and 401 on the flange used for the reverse function can be high-power LEDs and can be activated and operated by a set of wiring connected to a dedicated switch (on / off). In these embodiments, when the switch is off, the LEDs 201 and 401 provide the standard reverse function as described above, and when the switch is on, the LEDs 201 and 401 can provide stronger illumination (e.g., for roadside work). The warning LEDs 801 and 901 have separate dedicated wiring connected to a dedicated switch, as described above.

[0045] Figures 13 to 16 show top, side, exploded, and electrical circuit diagrams of exemplary combination lamps according to various embodiments of the present invention. Dimensions indicated are in millimeters. This embodiment of the combination lamp 10 (Maxxima M85417R) is a 5.5-inch round hybrid stop / turn / tail and backlight, comprising a 4-inch round stop / turn / tail (S / T / T) lamp 100 with 12 red LEDs 101 and a 5.5-inch back (BU) flange 200 with 9 white LEDs 201, these LEDs mounted on a support 502 (PCB), the support 502 comprising a back cover / housing 505 and a neoprene gasket 506 with holes 511 mounted thereto. The lens 103 covering the LEDs 101 may be colored (e.g., red) and may include the aforementioned protrusions 104. The lens 203 covering the LEDs 201 may be transparent and may include the aforementioned protrusions 204 and mounting holes 205. Lenses 103 and 203 can be fixed to each other or integrally formed. The combination lamps of Figures 13 to 16 may include mounting screws 507 (see Figure 21) and screw caps (mounting screw covers) 508, and have a low profile, sealed moisture-proof electronics, polycarbonate lenses, and housing components. The plastic screw caps / covers / inserts 508 can be pressed into the screw holes 511 after the combination lamp 10 has been installed in the vehicle, thereby preventing tampering with the combination lamp 10. In some embodiments, the screw caps 508 are configured so that they cannot be removed once installed. In some embodiments, the combination lamps of Figures 13 to 16 may be provided as a kit including two female PL3 connectors 509. In exemplary embodiments, the specifications of the combination lamps of Figures 13 to 16 are as follows:Specifically, it has 21 LEDs (12 red, 9 white); voltage - 12.8VDC; current - BU 0.2A, tail 20mA, stop 0.2A; dimensions - 5.5 inches in diameter x 0.5 inches deep; mounting - 3-hole flange mount (3) 3 / 16 inch holes, 1-3 / 16 inch notch for cable exit; connectors - (2) PL3 female, 10 inch wire; DOT / SAE-J593, J2040, J2261.

The combination lamps of Figures 21 to 26 may include mounting screws 507 and screw caps (mounting screw covers) 508, and may have a low profile, sealed moisture-proof electronic equipment, polycarbonate lens and housing components, and conform to DOT FMVSS108 / CMVSS1088. The plastic screw cap / cover / insert 508 can be pushed into the screw hole 511 after the combination lamp 10 has been installed in the vehicle, thereby preventing tampering with the combination lamp 10.In some embodiments, the screw cap 508 is configured so that it cannot be removed once installed. The connector leads 510 (e.g., seven blunt-cut wires) can be color-coded, for example, red (stop / turn), brown (tail), green (warning power), blue (back), black (ground), white (ALT / MODE2 / turn), and yellow (pattern change / SYNC). In exemplary embodiments, the specifications of the combination lamps shown in Figures 21 to 26 are as follows: Specifically, the LEDs are 30 (12 red, 9 white, 9 amber); voltage is 12.8VDC; current is 0.6A maximum current (stop + warning), BU 0.2A, tail 20mA, stop 0.2A, amber turn 100mA, warning 0.4A; dimensions are 5.5 inches in diameter x 0.5 inches deep; mounting is 3-hole flange mount (3) 3 / 16 inch holes, 1-3 / 16 inch cutout for cable exit; connector is 7 lead wires blunt cut 10 inches; DOT / SAE standards are J593, J2040, J2261, J595. The combination lamps in Figures 21 to 26 provide an integrated S / T / T and back and two-color amber / white flashing warning (SAE J595 Class 1 warning device), and can flash amber only, white only, or two colors of amber / white. Amber turn signals can be provided on trucks equipped with a dedicated turn signal wire (4-wire S / T / T circuit; see Figure 35). Figures 27 and 28 show the combination lamps of Figures 21 to 26 having 12 red LEDs 101 that provide taillights and stoplights, respectively. Figure 29 shows the combination lamps of Figures 21 to 26 having 9 white LEDs 201 that provide backlights. Figure 30 shows the combination lamps of Figures 21 to 26 having 9 amber LEDs 801 that provide flashing amber warning lights. In various embodiments, LED 101 can also provide any red turn signal, LED 201 can also provide any flashing white warning light, and LED 801 can also provide any amber turn signal.Figure 33 shows a schematic of the electrical circuit diagram of Figure 26, illustrating the section for input / output power management, the microcontroller, the red lens section for red stop / tail / turn signals, the white LEDs in the outer circle section used for reverse and warning signals, and the amber LEDs in the outer circle section used for warning and amber turn signals.

[0048] In various embodiments, the wiring specifications for the exemplary round hybrid combination S / T / T-BU warning lamp 10 shown in Figures 21 to 16 may be, for example, as follows: black - ground (-); brown - tail (+VDC); blue - reverse (+VDC); red - stop and turn (+VDC); white - any amber turn (+VDC), any warning "mode 2" (-GND); green - flashing warning (+VDC); yellow - programming (+VDC) (described in detail below). In various embodiments, the wiring specifications may be as follows: First, determine whether the vehicle has a dedicated turn signal wire or uses a common wire for both the stop light and the turn signal. Figure 34 shows a 3-wire stop / turn / tail wiring (red turn signal). If the vehicle uses a common wire for both the stop lamp and the turn signal, the red turn signal is used by connecting the red wire. Figure 35 shows a 4-wire stop / turn / tail wiring (amber turn signal). If the vehicle has separate left and right turn signal wires in addition to the stop lamps, connect the white wire to use the amber turn signal. The following steps then follow: Step 1: Connect the black wire to the vehicle's ground (-negative). Step 2: Connect the brown wire to the vehicle's taillight (+12V). Step 3: Connect the red wire to the vehicle's stop light (+12V). Step 4 (optional): Connect the white wire to the vehicle's left or right turn signal (+12V). Step 5: Connect the blue wire to the vehicle's reverse light (+12V). Step 6: Connect the green wire to the "flashing warning circuit" using a user-specified switch (+12V). Step 7: Program the yellow wire to the desired warning pattern. Holding the yellow wire to +12V for 1 to 2 seconds while the green wire is connected to +12V will scroll to the next flashing pattern (see Table 1). For single-color patterns, holding the yellow wire for 3 to 5 seconds will switch to another color (e.g., amber to white). To reset to pattern #1, hold the yellow wire to +12V for 7 seconds or more.Figure 36 shows 28 exemplary flashing patterns, but other embodiments may provide a different number and / or types of flashing patterns. In Figure 36, an asterisk indicates no available alternatives, and a superscript "1" indicates a repetition between colors. Step 8: You can choose "simultaneous flashing" or "alternating flashing". Figure 37 shows a warning wiring diagram for simultaneous flashing. Figure 38 shows a warning wiring diagram for alternating flashing (group 1 flashes in a pattern set to alternate with group 2). To make all lamps flash synchronously, connect all yellow wires together. This allows the lamps to communicate with each other. To use alternating flashing or "wig-wag" flashing, identify the lamps in "group 1" and "group 2" and connect the white wire of "group 1" to +12V. (In some embodiments, an optional amber turn signal may be disabled when the flashing warning light is on and / or when the reverse is activated. In other embodiments, combination lamps may be configured to enter different reverse / warning modes). Step 9 (Optional) - To use any "Mode 2" flashing warning pattern, a DPDT (Double-Pole Double-Throw) switch is required. See Figure 39. To access the secondary mode or second flashing pattern, connect the green wire to +12V and the white wire to (-) ground. During Mode 2, use the yellow wire (+12V) to program the desired flashing pattern (Step 7). Mode 1: Select the first pattern with the switch open. Mode 2: Select the second flashing pattern with the switch closed. The user can switch between the two selected flashing patterns by changing the position of the switch. To use a different operating mode in primary mode (Mode 1), a DPDT switch is required. Connect Group 2 separately to the other pole switch (common side). The other two sides of the switch should be +12V (alt) and ground (Mode 2). For a single-color pattern, connect the yellow wire and +12VDC (green wire) for 3 to 5 seconds to change the color.
