My wife's GTP had cool white LEDs in all the courtesy lights and dome/map lights when we bought it. They look incredible, but one of the map lights started blinking incessantly for some reason, so I switched them back to regular bulbs since I had a couple laying around. Started looking like a strobe light when the door was open. Funny at first, but it got old fast. I don't think it was a problem with installing them or anything, just a bad LED. I will probably order some new ones and switch them back.
