Step 1: Solder Led and Resistor Together

Step 2: Solder Your Switch to LED and to Battery Connector

Solder your switch to LED and to Battery connector. Now take one of your two pieces of command tape and place on back of switch. Place on battery, use second piece of command tape to the other side of battery. Place this firmly on lid interior. Tuck wires into cap but let the led hang down in the jar.

Note if you really want the wow factor use bare wire and connect more LEDs in a string. This will make the wires nearly translucent to the human eye. You can also use a black sharpe to darken wires down.
