I have a few blue LED's replacing the white ones in the A/C controls and such around the head unit. They need to be redone as they look like crap at the moment, and 3 of them burned out due to incorrect resistors that were installed (i'm doing this myself next time, instead of the way it was done by my installer.. by just trial and error). It WILL look bad ass when i finish with it, and it's doable.
