Hey guys, probably a very noobish question.... but i have a 95 hatch it has HID lights (before i purchased the car) and a headlight is out.. I checked the fuse first, then i took out the bulb and since i am new to HID lighting i was not sure what to look for with a bad bulb.. There is a white sphere in the center are of the bulb and it looks like it may be a bit dusty instead of white... i thought that may be a sign?? I will check my wiring but can someone tell me how i can tell if the bulb is bad? and where can i get a new one if it is??? No idea what brand the lights are (writing is worn off the HID box) all i know is that they are 6000k Hi/low..
Any help will be appreciated guys thanks alot in advance
