Powered by frame-mounted magnets, the bright arara Wheel Bike Lights are completely battery-free. Each light has an LED and a capacitor that passes by a set of neodymium magnets and retains a charge via magnetic induction.

These clever lights (two for each wheel) turn on when the cyclist starts rolling, and gradually dim after a full stop. They are water-resistant and can function perfectly at cold temperatures down to -15 ºF. Available in six colors, the arara lights are scheduled to be launched via an Indiegogo campaign set to begin on February 13.
