Useeme Bicycle Turn Signals make your bicycle rides safer by turning your regular hand signals into flashing indicator lights.
There is a motion sensor inside the wristbands which detects your hand movements. The sensor is attached to a microcontroller that continously evaluates sensor data and recognizes the patterns of hand signals. The microcontroller switches flashing LEDs on when you hold your hand out to the side, and off when you put it back on the handle. See it in action!
