Step 6Test the LEDs
Open up the battery case. Sometimes these cases have little retaining screws to hold them shut, in which case you'll need a small phillips head screwdriver to remove it. Pop in a couple AA batteries, close the case, and switch it on.
The three LEDs should immediately turn on, and begin to change color. If they don't, here are some troubleshooting tips:
If some but not all of the LEDs turn on, you probably have one or more LEDs in backwards; that is, you didn't line up all of the positive LED leads. You may need to pull off the crimp with a pair of pliers, or cut it off \with a wire cutter. There should be enough extra LED lead to re-crimp, but you'll probably need more butt splices, which can be found at Radio Shack.
If none of the LEDs light up, you may have reversed all of the LEDs (i.e., attached the red wire where the black wire should be, and vice versa). Rather than pull or cut the splices apart, put the batteries into the holder in reverse.
Still no luck? It could just be a bad connection. Try cutting off the crimps, re-stripping the wire, and re-crimping w/ new butt splices.
