finish unit
purchase a bicycle generator kit with headlight and taillight$14
other parts$0.00
total cost $14
I have also been working with some led lights . leds take very little voltage to make them work. i modifly the headlight with a 3 cluster leds and works ok. but what i need is to have some leds pointing into the reflector to make it brighter. i found something on ebay that might work real good. this has a total of 5 leds and some pointing to the side.
