ya, i actually have a led flashlight i keep in my backpack and a mount for it on the bicycle, it works, but its not as good as the two led one i was using. thats my backup, since as long as the flashlight works im good. i can even stop at a gas station and probably get a cheap led torch and put it on if the flashlight conks out. its too bad they really dont make any good lights for motorized bikes. its all stuff intended for bicycles, and with the vibration of an engine on a frame with no suspension it scrambles the hell out of their teeny little circuit boards. its weird, i checked it with a multimeter, the circut is providing 8v to the led board, but the two led's are totally dead. i wonder if i can just get 2 little 6v led bulbs, and two sockets for them and stick it in the case. might be more reliable. since the bulbs are replacable, probably wont fit in the housing though. or if it did it wouldnt be waterproof anymore.
