Ok, I did a little test with a "SHARPIE" marker. I marked over a few of the interior lights with red, and it worked pretty well. I think only red would work because amber is a shade of red anyway. Probably would not work with blue or green. I ended up using some "goo gone" to remove it. Just thought I would share my findings. The reason I tested it was because I am pretty sure you can easily remove all the color tabs behind the dash with the exception on the dials and levers in the heating controls, and the cig lighter piece. They seem to be preformed colored pieces, so I think you would need to use the sharpie (outside) on the levers and dials. Some lens paint on the cig., and then mold some of you own colored plastic peices for the rest of the lights and mount them between the light source and the dash somehow... Does anyone know if you have to remove the dash to get to the back of the cruise control panel and the heater and defroster buttons?
