Is it oem HID?
The bub will be black and grey in the round air bubble section when its blown.
Chances are your ballat is blown. In the V section there is a writeup on hoew to fix it with a ebay replacement for about $50. Dealer wants $380 for a new 1.

I am experiencing an issue also with my headlight, it is flickering and it turns off at times... I think there is a loose connection but I do not how to access the head light to tighten or to change the bulb if necessary, any help would be appreciated.

YMT- in my experience, flickering means balast is on its way out, color changing is usually the bulb on its way out.
To change the balast bumper has to come off, to change the bulbs airbox comes out and fuse box needs to be moved to reach in.

thank you ghettomike, I'm pretty sure its the balast then, any suggestions on where to get the part for cheap.. or any salvage yards that you frequent here in the GTA?

If this is factory HID then yes, replace ballast with aftermarket as the OEM is way too expensive.

I must ask, did you check the fuses? There is one fuse for each of the low beam and high beam bulbs. Which is a total of 4 fuses of course.

Yes I did check them and they were all fine. However I tightened the screws for the fuse box and the flickering went away completely!:thumbsup: I hope it isnt a temporary fix

It may sound stupid but do you know where the fuse is located?? Is it under the hood I would say it's not the fuse just because it flickered quite a bit then went out but I will for sure check... Thanks
