I guess I really wasn't clear. I don't want anything on my handlebars, at all. Part of the joy of going to a dynamo light is mounting it on the fork crown and cleaning up my handlebar. What I'm looking to do is add an open connection inside the fork leg that I can plug a charger into (similar to the unit zebede posted) and then throw that in a small gas tank style bag behind the stem. I also saw a cheapie from China that included an awful cell phone holder that I would give away immediately. It was about 30 bucks, though. I'm a $1.50 part and some wirnig away from a DIY one, though. So I'll probably move forward with that one.

If I could afford it, I'd do the top cap system, but yeah, that's pricey. I saw a DIY one that fit into your handlebar, but I'd end up having to run lots of wiring up and down the handlebar and I'm not sure I'd like that underneath my bar wrap.

I'm thinking maybe some 2-wire weatherproof connector that I can leave a female plug behind the fork and then some epoxy on the back end of a male connector and just pop that in as a place holder. But if anyone has any other ideas, or maybe a suggestion of a good connector, I'd love to hear it.
