Yes, there should be a vertical screw on it.

    Look around for a T-15 Torx screw for the horizontal and the vertical adjustment. It won't be a philips or flat screw head.

    Aiming the Headlights
    The headlights must be properly aimed to provide the best, safest road illumination. The lights should be checked for proper aim and adjusted as necessary. Certain state and local authorities have requirements for headlight aiming; these should be checked before adjustment is made.

    CAUTION
    About once a year, when the headlights are replaced or any time front end work is performed on your vehicle, the headlight should be accurately aimed by a reputable repair shop using the proper equipment. Headlights not properly aimed can make it virtually impossible to see and may blind other drivers on the road, possibly causing an accident. Note that the following procedure is a temporary fix, until you can take your vehicle to a repair shop for a proper adjustment.

    Headlight adjustment may be temporarily made using a wall, as described below, or on the rear of another vehicle. When adjusted, the lights should not glare in oncoming car or truck windshields, nor should they illuminate the passenger compartment of vehicles driving in front of you. These adjustments are rough and should always be fine-tuned by a repair shop which is equipped with headlight aiming tools. Improper adjustments may be both dangerous and illegal.

    For most of the vehicles covered by this manual, horizontal and vertical aiming of each sealed beam unit is provided by two adjusting screws which move the retaining ring and adjusting plate against the tension of a coil spring. There is no adjustment for focus; this is done during headlight manufacturing.

    NOTE: Because the composite headlight assembly is bolted into position, no adjustment should be necessary or possible. Some applications, however, may be bolted to an adjuster plate or may be retained by adjusting screws. If so, follow this procedure when adjusting the lights, BUT always have the adjustment checked by a reputable shop.

    Before removing the headlight bulb or disturbing the headlamp in any way, note the current settings in order to ease headlight adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building:


    1. Park the vehicle on a level surface, with the fuel tank about 1/2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall.
    2. If aiming is to be performed outdoors, it is advisable to wait until dusk in order to properly see the headlight beams on the wall. If done in a garage, darken the area around the wall as much as possible by closing shades or hanging cloth over the windows.
    3. Turn the headlights ON and mark the wall at the center of each light's low beam, then switch on the brights and mark the center of each light's high beam. A short length of masking tape which is visible from the front of the vehicle may be used. Although marking all four positions is advisable, marking one position from each light should be sufficient.





      Low-beam headlight pattern alignment









      High-beam headlight pattern alignment




    4. If neither beam on one side is working, and if another like-sized vehicle is available, park the second one in the exact spot where the vehicle was and mark the beams using the same-side light. Then switch the vehicles so the one to be aimed is back in the original spot. It must be parked no closer to or farther away from the wall than the second vehicle.
    5. Perform any necessary repairs, but make sure the vehicle is not moved, or is returned to the exact spot from which the lights were marked. Turn the headlights ON and adjust the beams to match the marks on the wall.
    6. Have the headlight adjustment checked as soon as possible by a reputable repair shop.

Adjusting headlights on 1996 fiesta (they are not high enough)


It is possible to adjust and aim the beams yourself. You can have several fittings on the headlamp to do this. There can be a simple phillips head on the adjusting screw or there can be a hex shaped head on the part. This hex is very small and you may need to buy a socket to fit it.

What you need to do is go to the Web and look for a diagram on where to Park the car properly. The idea is to Park maybe 25 feet from a wall or flat Garage door. Then you are to take some tape (chalk mark) and make a cross-mark to a specified height above the ground. By having the car in a specified place and the lights adjusted to a specified height, it helps to prevent Blinding oncoming cars.

Each light is adjustable left or right from the center of your car. You generally don't make the light wider than how the lights fit in the grille, and do not make the lights cross-eyed. With the States that require Annual Vehicle inspections the aim is part of the test.

This makes sense when you look at the different heights in vehicles. Your vehicle is not a jacked-up truck. Generally measure the ground to center of the headlight assembly on each side. Do not aim above that height level, below is best.

Common practice is to have the Drivers light lower than the passengers side.

Adjust headlights


the bulbs are pre-set in focus and if fitted correctly in the head light assembly they will be focused and adjusted correctly. Try adjusting the whole head light assembly by the 3 screws / adjusting knobs at the back of the assembly to aim the head lights correctly.

Head lights aimed to high


Hello...

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

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)

For Low Beams: 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.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

How do you adjust head lights on a1996 dodge intrepid after replacing both light assembly. Car was hit in the front & had to replace both lights on the car, lights are used from junk yard.


You should have two plastic nuts on each headlamp assembly, one will be for your high beams and one will be for your low beams.

The nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail (might see holes in your rail above the headlamp unit where the screws are hidden)

Fig. The head light alignment adjusters are located on the backof the assembly. Access holes are provided as necessary-2.0L Passat GLSmodel shown


Head lamps are adjusted from above. Do the following:
1. Open the hood
2. Look on top by the head lamps you should see two service holes (oneouter and one inner) where you will see a plastic adjustment screwwhich requires a hexagon wrench or a flathead screw driver that fits. Note the outer alignment screw is the hole located on top eg. driver side head lamps outter being the hole on the right side. innerbeing the alignment screw located in the hole on the left side of thedriver side head lamp assembly.
3. Lateral adjust/ horizontal adust is the right side hole.(which way to turn I've forgotten try incremental trial and error tilyou determine which way is left and which way is moving the beam to theright)
4. Vertical adjust is the adjustment screw located on theleftside of driver side headlamps assembly from above. turn counterclockwise to raise and clockwise to drop. its been awhile so i'm notquite sure .
5. Passenger side lateral and vertical adjust is symetrical. rememberoutter hole from above is lateral adjust and inner hole to the right inthis case for passenger side is vertical adjust.

2002 nissan xterra headlight is aiming up too high


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)
