LED Bottle Beacon

Step 3 Installing The Switch

This step is fairly easy. Remove the lid from your bottle. Look at the top and underneath to see if there is a mark right in the center from the molding process. Under the lid of this lid had a small "42". Mark that spot with a marker or pen. If you don't see and marks you can either just eyeball it and mark the center or do a little math and measuring.

Next take the small screw and screwdriver and line them up on the mark you made. (Be sure to have something under the lid to keep from scratching your work surface.) Press down while screwing into that mark until you are completely through. Check your size every few turns at the beginning to keep from making the hole too big.

Remove the small nut and washer(s) from the switch. Install the switch from underneath the lid. Place the small lock wash that came on the switch. Place another larger washer over the other. Install the nut to complete the switch installation. Tighten with small pliers.
