If you’re just looking to change your bulbs, you go right in back from here. We have it on a lift, but you can reach this just by laying down underneath. Like I said, this was all broken, so we'll take it out.

If you were just looking to change bulbs, press the tab on this here, turn counter clockwise, and bring the socket out. This actually is missing its bulb. But you would pull the bulb straight out, put a new one in, and then put it back in. Get it lined up and then turn it clockwise.

The fog light over here, there's a little tab on the bottom you pull down and you disconnect. Take the bulb out by turning counterclockwise. And then your new one will go in reverse. Push it in. Be careful not to touch the lens of the bulb at all with your fingers, because the oil on your fingers will make it burn out prematurely. You put it back in and then push this, reconnect, and make sure it clicks. If you want to adjust your fog lights on the back here, there's a Phillips screw. Clockwise we'll go down, counterclockwise will adjust the beam higher.
