I have a 2002 Acura TL-s, the other day one of my low beam HID's started to turn a redish color, by the next day it was getting dimmer and dimmer, three days later and it lights up for a few seconds then it will flicker for a minute, then go out. Does that sound like it has a bad bulb or ballast or igniter?

 

i would swap bulbs to see if it does it on the other side, that way if it does you know its the bulb thats going to need replacing.
