Step 1: Step 1: Drill Holes
Drill 4 holes in the pipe insulation for the LEDs and then cut out a rectangle for the switch. Each hole should be evenly spaced out, we did about 1.5" between each LED.
Step 2: Step 3: Cut Out Rectangular Hole for the Switch.
To cut out the rectangular hole, make sure to use sharp scissors. Also try to cut the hole a little smaller than the switch itself for the switch to fit snug inside.
Step 3: Step 2: Making a Circuit
The Circuit is a Series Circuit.
Step 4: Step 4: Connect Each of the 4 LEDs With Copper Wire and Solder
Step 5: Step 5: Connect 12v Battery to the LEDs Using the Copper Wire
Step 6: Step 6: Flip the Switch to Turn on and Enjoy.
