How to Adjust a Headlamp Beam on a 2005 Chevrolet Cavalier...

When you replace the headlamp assembly in the 2005 Chevrolet Cavalier, you must also adjust the headlamp beams. Like most vehicles, there are two screws located on the headlamp assembly that control the vertical and horizontal direction of the headlamps. Proper adjustment is necessary for adequate visibility during nighttime driving; bad adjustment can make it difficult for you to see or make it difficult for oncoming drivers to see, creating a potentially dangerous situation. You can adjust the headlamp beams yourself with a screwdriver in about 15 minutes.
Park the Chevrolet Cavalier on a flat surface facing a wall or garage door approximately 15 feet away. Park the Car so that it is perpendicular to the wall.

Lift the hood and remove the plastic trim panel above each of the headlights. There are three plastic fasteners that secure the trim panel; pry the fasteners out using a flathead screwdriver. Lift the trim panel up to remove. There are two adjusting screws beneath the trim panel, one on the top of the headlamp assembly and one along the outer side of the headlamp assembly.

Turn the headlights on so that they shine on the wall. Ensure the headlights are on the "dim" setting.

Adjust the vertical bolt, located on the top of the headlight assembly near the center of the vehicle to raise or lower the headlight, using a crosspoint screwdriver. Turn the screw counterclockwise to lower the headlamp beam; turn the screw clockwise to raise the headlamp beam. Adjust the headlamp so that the beam is below a driver's eye level.

Adjust the horizontal bolt, located on the outer side of the headlamp assembly to move the headlamp beam right of left, using a crosspoint screwdriver. Turn the screw counterclockwise to move the headlamp beam right; turn the screw clockwise to turn the beam left. Adjust the headlamp so that the beam shines straight ahead or slightly toward the center of the vehicle.

Replace the plastic trim panel and fasteners and close the hood. Warning: raising the lights too high can make it difficult for other drivers to see you.

find some level ground near a building or a wall, pull up close, then mark the height of the headlights horizontally on the wall, then mark the centers of the headlights vertically to make two plus signs in front of each headlight, then back up 30 feet and with the high beams adjust each headlight to each plus sign and your done. hope this helps.

try rechecking the placement of the bulb in the housing, it may be tilted

Turn on your headlights and locate the two adjustment holes that have the adjustment screws inside them on the sides of each headlight. The top hole has the vertical adjustment screw and the bottom hole has the horizontal adjustment screw. Turn the vertical screw clockwise to raise the beam and counterclockwise to lower; turn the horizontal screw clockwise to move the beam right and counterclockwise to move the beam left.

Depending on what vehicle, but most cars and trucks have the same set up. There is these long screws on top of the headlights under the hood. Normally it take a Allen wrench to adj.Then you simply turn clock or counter clockwise to rise or lower the headlights beams

This could be the adjuster screw. Park you car close enough to a wall or any other reflective surface and "mark where the beam is hitting the surface, then try turning the screw and gauge which direction the light beam moves. Adjust it to suit.

Pull up to within 20 feet of a wall or garage door and adjust them using a "star" screwdriver. The adjustment screws should be located just above the headlight assembly. Simply watch the beams as you turn the screws either clockwise or counter clockwise. At 20 feet the beams should be roughly 3 feet off the ground. Hope this helps.

Park your vehicle on level ground with the headlights near a garage door or wall. A good distance is 2-3 feet away from the wall or door. The location must be perfectly level and flat at a distance of 10 to 25 feet away from the door or wall.
Switch on the low headlight beams and mark the horizontal and vertical centerlines of each headlight beams on the wall using masking tape. This will mark the center of each beam with a +. The marking will tell you where exactly the headlight beams should be centered from a distance.

Move the vehicle back about 10 to 25 feet away from the garage door or the wall.

Keep the headlights on the low beam setting.
Use the markings you made on the wall or garage door to, check where the light shines and see if the centerlines still match up with the masking tape marks. If the centerlines of the two beams do not align with the tape marks, you can adjust one or both sides as needed.

Make the necessary adjustments with the lights still on while watching the light beams on the wall and your marks.
Turning the top adjusting screws in a clockwise direction will raise the beam while counterclockwise turn will lower it.

Turning the side adjuster screws will adjust the lights to the left or right.

Continue the adjustments until the center of the light beams are aligned with the tape marks. Then adjust the vertical alignment of both beams slightly below the marks on the wall. This will assure that the lights are tilted slightly downward so they won’t blind approaching motorist.

The will align bot lights, the high and low sine both are connected to the same headlight!!

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.

if you are looking down at the headlights from above there is a whiteish nylon screw that you can use either an allen wrench or a phillips screwdriver. Clockwise lowers, Counter clock raises.
