Should have titled: Third brake light wiring tips?
2009 Lancer ES:

I was rear ended and the center brake light was damaged. I bought a new one, LED just like the one it came with and when I plugged it in it wouldnt respond. I was thinking about running a tap from one of the brake lights in the body but there are 3 wires going into the brake light. One I know is ground, it is black. I dont have a multimeter but I think I may buy a fuse checker.

Im getting ahead of myself. Does the LED center light require a controller or any other voltage regulator or could I just splice it into the tail lights?

 

Solved!

There was no power at the socket so i ran to wal mart and bought a cheap 10$ cuttable red LED strip, spliced it to the active brake/tail light that was 11.8V when the pedal was depressed. I had to break the housing a little to slide the LED strip in but it was already broken from the guy rear ending me.

Prolly not DoT approved, but itll pass inspection now!

 

Hopefully that LED strip is weatherproof
