I have had my kit for a few years now, and i have been starting to notice that my driverside bulb its starting to change color. I have a 35w 6000k Apexcone kit, and one bulb is blue-ish, and the changing one is white, and turning pink. I pulled the bulb out to look at it, and in the center of the bulb (the little bubble) it is turning yellow, I assume that it isnt suppose to be like that? I think the bulb is getting ready to take a crap! any help?
