Ive always wanted lights to flash with the bass in my truck but the store bought lights don't work very well so I decided to build them myself. I used 100 each of red, green, and blue LEDs. I accidentally recorded upside down cause I had to use my ipod to record cause my camera doesn't have a mic.
Step 1: Required Materials
For this instructable you will need the following tools:
Small Needle Nose Pliers
300 LEDs (for me)
60 51 ohm resistors
Wire (I used speaker wire)
Step 2: Make holes
Step 3: Insert LEDs into proper holes
Next you need to put the LEDs in the holes in a pattern you like. I put them RGBRGBRGB.
Next you twist the ends of the LEDs together leaving the first positive and last negative sticking out to the side. Make sure you do it like in the pic or it won't work right.
Step 5: Solder the Resistors
Next solder the resistors together to make a negative "line" and do the same with the positive side.
Step 6: Attach the wires
Step 7: Install
To install this I pushed needles through the board and bent them so I could slide it into the headliner.
