Pm me with what you want and we can discuss. I'm thinking a red strip up the seat tube for a rear light, build my own invertor to run off a LiPo rechargeable battery which could drop in the seat tube and weigh considerably less than what you have, or a none contact dynamo type system driven off the rear wheel (intensity will vary with speed quite a bit though).
