Sr. Eco focuses on the design and production of innovative, environmentally-friendly products.

The Xbat series of lights features different models for different bicycles. In all cases, all Xbat lights automatically turn on when a bicycle is ridden, without any batteries or direct contact to the rim of a bike's tire.

Furthermore, cyclists no longer have to worry about changing batteries; the magnetic induction employed by Xbat lights uses only a tiny bit of the bike's momentum to generate a clear, bright light whenever a cyclist starts to peddle; Xbat lights are completely silent, unlike traditional dynamos and, best of all, Xbat lights not only look fashionable but also are very easy to mount on a bike.
