You're trying to distribute the lights to those you come across the way while you're riding.

Another way is to get funding and buy the combination product like the bundled deal: Cygolite Metro 420 with the Hotshot rear light. Then sell it to the local bike shops with the proviso that they offer it on all new bikes sold.

This may not be a money maker for you. But it will get the lights in the hands of the riders who will take pride with their brand new bike.
