Step 7: Attach LEDs to the Case
This step explains how to use the glue dots that come with the kit to attach the LEDs to the battery case. Alternately, you may use a small dab of hot glue, which is actually slightly sturdier once it's set.
Gently peel the strip of glue dots open, being careful not to touch the blobs of glue, or get them stuck on anything (they're like way sticky). Cut the backing so you have a single dot, and affix it to the case, near the switch.
Press firmly, and peel off the backing (if needed, use your finger to help the glue dot stick to the case, but try not to touch the glue more than necessary).
Now firmly press one of the crimped splices (it doesn't matter which) against the glue dot.
