Nice work! I've got a light coming for my bike soon as well. I ordered one of the Baja Minibike lights from the mfg. and will use a battery in my storage bag much like you did. The rear is running off of the mini-mag that I got from eBay. Right now my current front light and rear are running off the mini-mag but the front is not even close to being bright enough to ride at night or even dusk.
