This kind of flashlight work with the action of a dynamo by the movement of the wheel, but it was broken so I dissassamble the whole thing an add a pair of Leds.

U know something ...i dont have a clue about electronics but still working ...I used battery of cellphones and two leds of 3 volts...that´s all.
I had been used this about a year and still lightning...I think is good luck. let me do the Math and I´ll give you a better method...BTW...thnks for the vote
