Step 2Disassemble the Flashlight and Mod the Circuitboard
The first part of this is easy and most likely you've done this before to flashlights, pens, anything that screws apart . . .I know I have. Basically simply unscrew everything but make sure you remember how to put it all back! In the light end the circuit board with the LED's will be screwed in with tiny little (usually phillips) screws. These are really easy to lose so put them into a jar or a bowl or something.
Now you have the circuit board take the time to admire it's intricacy (or not . . .as you wish) and clip it into your handy hands. Choose one of the LED's that won't interfere with anything major if it's removed and replaced with a wire. I chose one from the edge so that I wouldn't have to worry about wires crossing in and around other LED's.
Carefully unsolder the chosen led and save it for later. Make sure you mark positive and negative on it now since the leads will have been clipped and one won't be longer than the other. I used a sharpie since it wipes off easily later. In the LED's place solder your wires. Clip the other end of the wire leaving plenty of slack to trim up later once you're done running it. At this point it's wise to test out the circuit board via multimeter or by supplying power and then touching the loose wire to the led to see if it lights up (i.e. the poor/lazy man's way). Once you've got it working proceed to the next step.
