ChapStick LED Flashlight

Step 6 Assembly

Put the top portion with the LED (finished in step 3) into the top of the ChapStick tube and push it all the way down until the wire is exposed. Cut the wire attached to the tactile switch short enough to where the length from the spring to the bottom portion is slightly less than the length of the battery when soldered. (This will force the battery to be slightly compressed against the spring and the base when inserted into the tube so that it will make good contact.) Solder the wires together and cover with heat shrink tubing. Slowly push the battery into the tube (which will raise the platform to the top) and snap the bottom of the tube in place and you're done.
