Powered solely by the cycling motion, they light up as soon as the cyclist starts to pedal providing always-on lighting, with no requirement for a battery. The lights ensure that cyclists can be seen from up to 1km away by motorists and from any angle even the side, which is a major blind spot. In addition, the lights store the energy used which enables them to stay on for up to 5 minutes after the pedalling has stopped.
