How do i adjust my headlights on my gto

you don't
it is part of the head light assembly
the question do you have the correct head light assembly on the right side as there are right and left hand headlights

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.

best to let a garage adjust head lights because you need equipment to adjust headlights, because you could blind other drivers on coming traffic on the opposite lane causing accident. best let garage adjust headlights wont charge you much.

there are 2 adjustment screws for headlight adjustment one for horizontal and one for vertical.the other adjuster looks the same but will be on the other side of the headlight and positioned the same or in a slightly different spot.

Most Fords I've seen use a 3mm or 4mm shaft at the top of the headlights under the hood. One does the vertical, the other does the horizontal. Use a 1/4' socket set to make the adjustments.

There are two adjustment screws at the top of each headlight. They are visible when the hood is up. Use an Allen wrench (hex) of the proper size to turn one screw to adjust the height and the other for lateral adjustment.
It is best to position the vehicle on a level surface a facing a wall or garage door. The vehicle can be about 8 feet from the wall during adjustment.
Adjust the light left/right and up/down with those adjustment screws. The head lights should point somewhat straight ahead at the same height as the headlight itself and the same distance apart.
After adjustment, park the car on the street at night, turn light son and stand about 50 feet form the vehicle to see if either light (low beams) seem too high. It would appear brighter if it is too high, dimmer if it is too low.

• Always adjust lights with optical headlight aimer VAS 5107, using detailed aiming procedure and specifications
• Low and high beams are adjusted simultaneously.

Left headlight (adjustment screws for right headlight are mirror image):
1 - Lateral adjustment 2 - Height adjustment

• Access adjustment screws through hole in lock carrier (Phillips head or socket head).
• Turn the adjusting screws for lateral adjustment -1- and height adjustment -2- until the correct setting is achieved.

NOTE: Where equipped, ensure equal movement/function of headlights during automatic headlight range adjustment.

if you have put bigger tires on the vehicle or lifted it you need to adjust the headlights they sell the tool at any auto parts stores its a small rachet tool you turn to lower the head lights

This is how to adjust 04 Optima headlights:

For all descriptions, assume that you are standing BEHIND the light assembly.

On the back of the headlight assembly you will see the bulb cover (round cover with tabs) stamped "OPEN" and an arrow showing which direction to turn to remove. Look toward the 8 o'clock position for driver lamp, 4 o'clock for passenger lamp of this cap. Partially obscured by the sheet metal you will see a black screw 3/4 exposed on the headlight assembly. It is at the edge of the sheet metal and very difficult to see, but it,s there. You may need to remove the assembly to get a better look. If needed, see below for lamp assembly removal.

How to remove the headlight: There are two 10mm bolts holding the assembly in place. One is above the headlight and the other one is between the headlight and the high beam light. Unplug the two harnesses that hook into the headlight, if needed, and it is ready to be removed the car. Gently work it out of position.

Take a Phillips screwdriver and turn the black screw - it adjusts the light vertically. Turn it counter-clockwise to make the light go up and clockwise to adjust down. Its as easy once you find the screw.

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.
