Can't help with the fashion, but here's a couple of things to check out:
-Go to the Electronics forum here on BF...Good for answering your lighting questions- dynamo or battery powered.
-Have you thought about converting your bike into an e-bike?
Bionx is reputable, but search/ask in the E-bike forum here in BF for more knowledgeable info.
Other than that, I've got nothing.
