I bought this LED flashlight for a few bucks, expecting to take it apart and gut it to make a headlight. I figure, cut a couple wires, solder up a battery holder, good to go. Only problem is, there's all kinds of circuit boards (well, okay, 2 circuit boards) that I don't know how to work with. The 5 LEDs are attached to one board that has 3 wires coming off it--two red and one black, which makes sense, since the light has a "low-high beam" set up where it's either 3 on or 5 on. I figure one red wire goes to the hot side of 3 LEDs, the other red goes to the hot side of the other 2 LEDS, and the black is the common negative. However, these three go to this other circuit board that's all kinds of complicated and attached to the 5-way switch and the batteries. This whole mess runs off 4 AA batteries. Here's my question: Is it safe to assume that these LEDs run off 6vdc (4 AAs by 1.5 volts each) and I can cut those three wires and hook them directly to batteries and a switch? Or is there likely to be voltage-reducing stuff on the other board so that when I hook up the batteries and flip the switch, it'll let the smoke out of the LEDs? :mrgreen:
