Congratulations on creating a beautiful lighting system. I suggest adding a small piece of metalized tape (the kind they use to seal furnace ducts) to the side of each headlight to keep the bezel from popping off. The little dimples and grooves used to secure the bezel are not reliable when bounced around on the road. One of mine popped off one block from home on its maiden voyage. The tape is cheap insurance and beats searching the grass by the side of the road or getting it run over by traffic as it rolls down the street.

Also, don't forget a fuse or circuit breaker. The 7AHr battery can technically jump start a car and will melt PVC insulation right off of the wires in an instant if given the chance.

Been there, done that.

Edit: D'oh, I already said that...above, but now I have pictures. Woo Hoo!
