ok, so i have a set of mcculloch hid's on the car. well, i removed my headlight, and put it back on and now when i turn them on, one of the bulbs has changed colors, and become more yellow. is this a good sign that i put a finger print on it, and its going bad? or could i have a balast that has just decided to peace out? hmmm. any help is appreciated guys. thanks!
