My aftermarket stereo has a blue display and I have blue leds in my dome and cargo lights now and I like the way it looks in my car. I have a black car with black interior so it might may a bigger difference with other interior colors. I have been thinking about changing the dash lights but have not pulled the dash to see if I can do that yet. I have seen some posts on the forum that say the dash is all led but it doesn't look like led's to me. Anyone have info on dash/gauge bulbs ?
