LED Turn Signal Jacket for Clear Low-Light Rider Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcyclists and cyclists face accidents, injuries, and fatalities due to limited visibility and lack of effective turn signal indication systems, especially in low light conditions, as traditional signaling methods are not clearly visible or understood by other road users.
Innovation Solution
A modified garment with integrated LED lights on the arms, front, back, and shoulders, allowing independent activation via buttons on the sleeves, illuminating sequentially to indicate turns, and featuring waterproof materials and USB rechargeable battery packs for increased visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional turn signal methods (hand signals, helmet lights) are used, then the signaling function is provided, but visibility and clarity of turn indication to other road users is insufficient
Solution Approach 1:
The turn indication system is segmented into multiple independent LED light elements arranged in linear arrays on each sleeve. Each sleeve contains its own set of LEDs that can be independently controlled, allowing clear directional indication without confusion from other light sources on the body.
Solution Approach 2:
LED lights are strategically positioned on the sleeves (away from the body center) to provide localized turn indication at the extremities. This placement ensures that turn signals are visible from the side and front without being obscured by the body or conflicting with rear-facing lights.
2Illumination intensity
If multiple lights and features are integrated into a helmet, then visibility is improved, but the system becomes heavy, expensive, and confusing to decode
Solution Approach 1:
The turn indication function is extracted from the helmet and relocated to the garment sleeves. This separation allows the helmet to remain simple while the garment provides the specialized signaling function, avoiding the complexity and weight of integrating multiple lighting systems into the helmet.
Solution Approach 2:
The garment serves multiple functions: it provides turn indication through sleeve LEDs, rear visibility through back LEDs, and can be integrated with the vehicle's existing signaling system. This multi-functionality in a single garment avoids the need for separate helmet-based systems.
3Illumination intensity
If existing bicycle lights (forward directed light, rear reflector, tail light) are used, then basic visibility is provided, but they cannot signal intended movement or are not visible enough
Solution Approach 1:
The LED lights on the sleeves are designed to dynamically indicate turn direction by illuminating only the relevant side. The system can selectively activate left or right sleeve LEDs based on the intended turn direction, providing adaptive signaling that responds to the rider's intended maneuver.
Solution Approach 2:
The turn indication is added in a new spatial dimension by placing lights on the sleeves rather than on the front or rear of the vehicle. This lateral positioning of LEDs provides turn information from the side, complementing the existing forward and rear lighting dimensions.
4Ease of operation
If motorcyclists rely on hand signals or vehicle-mounted turn signals, then turn indication is provided, but visibility to other road users remains limited especially in low light conditions
Solution Approach 1:
The mechanical hand signaling system is replaced with an electronic LED lighting system. The LEDs provide illuminated turn indication that is visible in low light conditions without requiring physical hand movements, substituting mechanical action with optical signaling.
Solution Approach 2:
The system uses colored LEDs (typically amber or white) to provide visible turn indication. The colored light emission enhances visibility in low light conditions and distinguishes turn signals from other light sources on the vehicle or environment.

Function Achieved in This Case
Enhances the wearer's visibility and clearly communicates intended turns to other motorists and pedestrians, reducing the risk of accidents and fatalities by providing a cost-effective, easy-to-use, and stylish solution that is not dependent on posture or positioning.
Implementation Method 1
LED lights positioned on the sleeves in an arrowhead shape running sequentially from shoulder to wrist
Data Source
AI summary
This present application discloses a turn direction indicating jacket having a plurality of directional indicators independently actuatable via a switch and a portable power supply. The invention illuminates the lights in sequential fashion from the wearer's shoulder to his or her wrist with an arrowhead at the base, there ensuring that other motorists and pedestrians alike are aware of the wearer's presence in traffic and the wearer's intended traffic movement.
