I first tried using brake lens repair tape with the stock incandesent bulbs. Its works surpringly well except the blue on the temp range turns purple (unless u don't filter this area). However, after redoing my stock stereo LEDs, the red didn't match perfectly. I wanted a deep deep red, which my stereo has from the 660nm LEDs.
Replacing the stock incandesents with #74 LED bulb results in very unevening lighting. So I made my own custom array of 660nm SMD LEDs. Enjoy the pics!!
