My driver side headlight went to a dim color about a week ago and then went out entirely. I am attempting to change the bulb but I am lost on how to get the light out of the socket. Is this a problem with the bulb or the igniter? Or both? If so can anyone give me a step by step on how to change this out? Dealer is asking 500 to do the job and that just seems a little steep for a bulb. Also, when I purchased new tires a few months ago my passenger side light started and continues to flicker when I hit bumps, does anyone have any idea how to fix this issue?
