2018 Ram 1500 Headlight adjustment screw no longer moves the Headlight up or down.

the high beams work fine and power goes to the only when vehicle is on when it is off no power gets to the low beam side of the right headlight. ????????

Okay, This depends on your State laws, because some States require the headlight aiming to be performed at Inspection time.
There are small hex shaped adjustment screws around your headlamps. They require very small sockets of perhaps 1/16 th of an inch and barely fit next to the headlamp housing. At most there will be 1 for up and down and 1 for left and right so two adjustments for each lamp housing.

Unless the housing has 2 separate independently moving compartments for each low and high beam you are stuck with the setup of the low beams. This means you have to adjust the low beams and the high beams are not independently adjustable.

If you find that each lamp is independent, then disconnect the low beam bulbs and adjust the high beams at night or in a garage and put some tape or marks for a level line for a pattern. Then adjust the beams with the drivers side slightly towards the center of the car and the passengers side to the right of the car.

This is similar to how the low beams are set. You can then raise the beams up to be higher on the passengers side for better visibility. Opinions on this vary.

Myself, I set my passenger beam to hit the curb or right lane marker when I drive on a multilane highway. This way the right side of my car is projecting a beam that keeps me centered in my lane by just keeping my passenger light on the lane marker. It works good in fog and around curves.

The State of Texas was one State which checked headlamp alignment with every annual Vehicle Inpection. The idea is to keep from blinding oncoming motorists.

There were some Magazines which evaluated the lighting in new cars as part of their consumer testing. Some of the Oldsmobiles, I believe, were cited for poor visibility and a term called "cutoff" was used to describe the lack of *********** by the headlight beams.

Now the low beams adjust to the same pattern. For some reason I remember having the low beams at 42 inches height and at a distance of 25 feet. These would be the marks you would try for on the garage wall.

You might want to browse about the magazine articles. You can try the new improved bulbs to help too!

I believe these have adjustment screws between the headlight bulb and the headlight bezzle on the top and bottom center of the headlight.

Crouch down so the bulb would be shining right in your eyes if it were on. You should see the adjustment screws I'm talking about in there.

You should be able to shine the lights on a garage door or wall and move the screws in or out to get the desired beam height you're looking for.

on rare occasions I have seen both low beams burn out I would buy one new bulb and replace either one in the truck if the low beam works with the new bulb then replace the other one as well if the low beam still does not work then replace the headlight switch also check to see if the headlight switch recall was done on that particular truck or if it was under that recall,they had a problem with some of the ram trucks burning up headlight switches but I would check to see if yours might have been one of them there is a wiring upgrade that they will put in at the headlight switch that will cure that,like I said though check to be sure first yours might have not been one of them.

its probably the muliti function switch on top the steering column

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.

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 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.

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.

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.

Hope helped with this information. Good luck (remember rated this help).

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.
