Locating vertical headlamp screw on 2016 F150

1. Park your car on a level surface, facing a flat wall or garage door. Make sure the car is at a normal operating temperature and that the headlights are turned on.
2. Open the hood and locate the headlamp adjustment screws. These are usually located at the back of the headlamp assembly, near the firewall. There should be one screw that adjusts the vertical aim and another that adjusts the horizontal aim.
3. Use a Phillips head screwdriver to adjust the screws. Turning the vertical screw clockwise will lower the beam, while turning it counterclockwise will raise the beam. Turning the horizontal screw clockwise will move the beam to the right, while turning it counterclockwise will move the beam to the left.
4. Adjust the headlamps one at a time. Cover one of the headlamps with a thick cloth or cardboard to prevent any stray light from affecting your vision while you adjust the other headlamp.
5. Aim the headlamps so that the center of the beam is at the same height as the center of the headlamp lens. The horizontal aim should be straight ahead, with no visible lean to either side.
6. Test the headlamps on a dark road to make sure they are properly aimed. If you notice any unevenness or misalignment, make further adjustments as necessary.
7. Close the hood and enjoy your properly adjusted headlamps.

It's important to note that if you're not comfortable working with car electronics, or if you're unsure about any of the steps involved in adjusting your headlamps, it's best to consult a professional mechanic or authorized Jaguar dealership for assistance.

Owner's manual says high beams will be adjusted by correctly adjusting the low beam.

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.

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.

If you have one adjustment screw, it will control your vertical aim. If you have two adjustment screws, one will control your vertical aim and the other will control your horizontal aim

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.

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.
