I changed mine to red
I changed mine to red. It's time consuming but pretty simple. They use the same bulbs as your over head reading lamps. I think you need 5 or 6 of them. The one problem I found is that the Gas gage light isn't the same, its a tiny LED. Hard to find in red. However, even with the green tinge in the actual gauge, It comes out nice and red, looks so phat.
To do it you need to remove the center console so you can remove the dash panel that surrounds the stereo, climate controls and gauges. The panel is held in by two screws beside the ash tray (hidden by the center console) and 3 screws above the gauge cluster. Other than that its held in by snaps. Once you've got it loose, you have to disconnect the wiring harnesses for the Cruise control button, Fog light button etc... And disconnect the cable that runs to the climate control lever to the left of the center vents. This can be a very annoying process because they don't give much excess wire

Once thats done, lower the steering wheel and remove the dash panel.
Next you have to remove the gauge cluster which is held in by 4 screws. The lights are held in at the back by little round screw in caps, remove each one with a slot screwdriver, takes like a quarter of a turn and change the bulb. It sounds more complicated than it is, and its well worth it
After you've replaced the bulbs, turn the car on and test it before you reassemble the dash, I didn't think to do that and one bulb ended up being out. I think everyone in the neighbour hood heard me swearing

Good luck, if you need any more help lemme know...
