Step 1: Supplies used,
2 5mm LED Holders
Heat shrink wrap
Some thin gague wire. I used an old phone cord.
2 tops off a Gaterade bottle
Step 2: Putting it together
(Note, the longer leg on the LED is positive, so hook your wires up accordingly.)
Add some thin wire to the LED's(I use an old phone cord), and attach the wires to your speaker wires. This will only work on amplified speakers, or speakers that plug into the wall.
