I have a 2002 DX w/o tach and Im looking into switching to P5 gauges (white face w/ tach.) The conversion isn't my concern, its the lights. The P5 gauges are red-backed while my DX dash lights are all green.. Anyone know how to switch from green to red? Im not a big fan of the christmas color scheme..someone mentioned to me it was just a dimmer switch..but I'm not very sure..feel free to help..Thanks!
