How to adjust headlight beams

What is the proper adjustment/
Head light adjusters are part of the head light assembly and yes high and low beam are adjusted as one unit normally. Proper adjustment is done on a machine, at an equipped facility.

low beam and high beam is in the one setting unless you have separate headlights
procedure is to place the car on level ground 3 feet from a wall that reflects the head light
draw a cross on the wall at the height of the center of head light lens
switch on the head lights (high beam)and you will see the center beam of high beam on the wall
using the screws at the back of the assembly adjust that spot to be pointing slightly to the left if rh drive ot left if lh drive and about 1 inch below the line that you drew on the wall
when you have that correct , it will put the low beam in the correct legal position
if the rear of the vehicle is sitting down , trailer of caravan on , the the head lights have to still be adjusted to legal setting

If you look just behind the headlight glass from the top, you will see two holes with 7mm hex head screws. These will adjust your headlights up, down, left and right.

If you look at the top of the head light assembly with the hood open just past the top rubber seal, you will see an alan head adjustor screw. This will adjust the low beam light up and down. the high beams are fixed. I would suggest shining your headlights on to a wall or garage door to get them to the same hight you need.

I am assuming that the design was not changed from my 2005 updander to your 2008. I had to adjust mine while on a road trip. We had a lot of people and stuff in my vehicle which made the headlights shine higher than normal. I was getting a lot of on commig traffic flashing. I was able to ajust them down fairly easy with those adjustor screws. Hope this helps.

Adjustment are located on the sides of the headlight assembly. One adjusts up and down (side) and one adjusts side to side (back) park about 20 feet away from a wall and adjust to center Your beams should be about 6"-8" lower than the headlights and about 6" inside the diameter of the lights

Yes you can. There is an adjustment screw at the top of each head lamp and you just turn them out or counter clockwise and the beam will come down. You may also have to adjust them side to side also. There is an adjustment screw as well.

On the top of the headlight is a star shaped fitting. This is the adjuster. It works by spinning a gear that is mounted to a shaft to position the headlight up and down.

I've seen them fall off, where the headlight is not adjustable, infact, the bulb sits at the bottom position and bounces up and down.

Adjuster is not available as a part from GM, you are required to replace the headlight.

look into the assy with a high powered flashlight you will see phillips head screws or torx head that will allow you to ajust up down sideways.

with your hood poped look on the framing above the head lights. there are about 2, 1 inch wholes above each headlight. If you look down in them you will see torx shaped studs. One turns up and down the other turns from side to side.
