Smart LED lights programmed to detect your bike speed and blink according to the state of your bike: stationary, moving, or braking.
The lights go on each of the front and rear wheels. Each arc of lights has 12 LED lamps that is powered by an usb-rechargeable lithium-ion battery. An accelerometer provides speed and orientation data, allowing the system to illuminate LED lamps only when they are at the front or rear of the wheel.
The Revolights design also provides a wider coverage for illuminating the path in front of the biker, as well as making the bike more visible to vehicles behind it.
