Reelight, based in the Netherlands, manufactures battery-free bike lights that are powered by magnetic induction. Most of their lights are fixed-mounted and many require no wires to set up. A magnet attached to the wheel spins by the light, inducing a charge and powering the light.
Reelight 100
The SL100 series front and back lights are semi-permanently mounted to the hub axle. Magnets attach to the wheel and induce an electric charge in the light. These are small, 1 or 2 LED lights that are primarily designed for visibility. The low-down position may inhibit visibility from a distance. The lights are only available in a front-back pair.
SL 150 Rear
