Re: Headlight Assembly; What specific light is this? DRL? PICTURES
That is the parking light, also referred here as the "peanut bulb." IIRC it's either a W5W or 194 bulb type, think those two are pretty much interchangeable. You can get to it without removing the bumper or the headlight assembly by going through the wheel well after removing the liner or at least loosening it enough to get your arm/hand back there. There is a screw on cap on the underside of the headlight assembly that needs to come off to get to the bulb. The DRL's are above the fogs.
