ALIGHT is a retractable lighting device that attaches to the rear seat of a bicycle. It utilizes technology from stretchable electronics and a retractor mechanism, which allows it to be coiled up or extended out. By extending the light to the rear wheel axle, it creates more surface area and a larger visual impact. ALIGHT emits a bright green light, which will turn red when braking and flash yellow when turning left or right. The curve in the extended position allows it to be seen from all angles. Using features from taillights, it assists the bicyclist in traffic. All this means ALIGHT breaks the communication gap, improving safety.
