That wouldn't be bad at all. and If I could get a brake switch that would work I could also run that, I would just need to run the hot from the battery to the switch and from the switch to the tail light and put two runs of LEDs in the bar instead of just one. (one for the running light, and one for the brake) how big of a battery do you think I should use? hopefully nothing too big that I would need to fab an in frame box for.

I guess I do have an OEM rectifier on my bike, I just now remembered that. but it probably wouldn't put out enough power to charge a battery. the Previous Owner had some junky halogen lights on the front of the bike, I still have those things somewhere.
