How to adjust 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.

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.

Hard to say without looking at it. Usually it is 2 reasons: the bulb is not fitted properly or the headlight itself is dull (yellow). In the second case you just polish the headlight with some car polish until it is clear. Anyway i am sure you fixed it by now....

Open your hood and look at the headlight assembly from inside the hood. You will see screws that you can loosen to get the headlight covers off, and the bulbs should just be "screwed" in the headlight units. There shouldn't be any bolts and screws on the outside. Also, to adjust your lights, you should have an adjustment "screw" on top of the headlight unit when you open the hood.

AIMING THE HEADLIGHTS

On 1989-91 vehicles, the headlights can be aimed using the adjusting screws located above and to the side of the headlight bulbs. A rough adjustment can be made while shining the headlights on a wall or on the rear of another vehicle, but headlight adjustment should really be made using proper headlight aiming equipment.
On 1992-98 vehicles, the aerodynamically styled headlights necessitate the use of headlight aiming kit 107-00003 or equivalent. The adjustable aimer adapters provided in the kit must be used to aim the headlights. Adjustment aimer adapter positions are moulded into the bottom edge of the headlight lens. Set and lock the adjustable adapters, attach each adapter to its mechanical aimer and aim the headlights according to the instructions in the kit.
Headlight aim adjustment should be made with the fuel tank approximately half full, the vehicle unloaded and the trunk empty, except for the spare tire and jacking equipment. Make sure all tires are inflated to the proper pressure.
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 guide, 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.
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.

See Figure 6

1. 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.
2. 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.

See Figures 7 and 8

1. 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.
2. 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.
3. Have the headlight adjustment checked as soon as possible by a reputable repair shop.

Make sure the bulb was put in correctly and sitting flat as bulb replacement does not require head light adjustment.Check head light bulb before attempting to adjust

first off if you paid to have it replaced then i would take it back to them for the adjustment if not there will be some sort of adjustment screws on the whole lamp assembly not sure exactly where on a focus but if you are persistant you will find them. then find a spot to park car close to a wall so you can see the lights projected on the wall and adjust to the driver side level

before you do any thing make sure that the bulbs you installed are perfectly seated in its place inside the assembly if it is not seated properly the lights wont focus properly
