"The lights flash powerfully with twin LED’s using the power generated by magnets attached to the spokes of your bicycle. Why was it not invented before?
There is no need for batteries or dangling wires – never, ever!
The lights are easily fitted to any bike, and are a great safety device for you or your children. The lights are always on, day or night, constantly flashing.
And just as important, there are no batteries to buy or to throw away when used.
