Rhythmo / Safety Light


Rhythmo is a safety light system for sportsmen that utilizes the user’s kinetic energy for battery charging with help of electromagnetic induction. There is no danger of running out of power in a critical situation.
Because the light shines across 180° degrees a good visibility is given.
LEDs & a mirrored background provide as much energy efficiency as possible. In terms of sustainability, Rhythmo functions much better than other conventional battery-powered safety lights.
Thanks to its clipping system, Rhythmo can be used in various situations like attached to a jogger’s arm, to a bicycle seat, and so on, making it a multi-purpose tool.
