on each headlamp assembly, there will be either one or two plastic nuts that you can turn.

If you only have one nut on each, that will adjust the vertical aim of the headlights.

If you have two nuts on each, one will adjust the vertical and the other will adjust the horizontal.

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

1.) Open the hood of your van
2.) On the passenger side of the vehicle, look behind the headlight enclosure. You will see a set of wires running into the back of it. This is the power clip. Either with your hand or a flat-head screwdriver, pop the power clip off.
3.) There is a plastic ring encasing the light bulb. Turn the ring counter-clockwise and pull it out of the socket and set it aside.
4.) Pull firmly on the light bulb to remove it.
5.) Place the new light bulb into the same opening. Be careful not to touch the glass part of the new bulb. The oils in your skin can substantially reduce the life of the new bulb.
6.) Replace the plastic ring and turn it clockwise to lock it in place.
7.) Reattach the power clip to the back of the bulb.
