Headlight and Foglight Adjustment/Aiming/Alignment

I. Vehicle Preparation for Headlight Alignment

1. Check for and correct any burnt out bulbs.

2. If the vehicle is equipped with headlamp leveling, be certain that the headlamp leveling switch is in the 0 position.

3. Repair or replace any ineffective, worn or damaged body or suspension components that could hinder proper lamp alignment.

4. Verify proper tire inflation pressures (for stock vehicles, the specified tire inflation pressure can be found on a sticker located on the driver's side door jamb).

5. Remove any accumulations of mud, snow or ice from the vehicle underbody and clean the front lamp lenses.

6. Verify that there is no load in the vehicle (cargo or passengers), except for the driver.

7. The fuel tank should be FULL. Add 2.94 kilograms (6.5 pounds) of weight over the fuel tank for each estimated gallon of missing fuel.

8. Verify correct vehicle suspension height.

================================================== =======

II. Headlight Alignment Screen (Surface) Preparation




The procedure that follows will prepare a suitable headlight alignment screen.

1. Tape a line (#1) on a level floor 7.62 meters (25 feet) away from and parallel to the flat wall that will be used as the lamp alignment screen. The level floor will be used as the horizontal zero reference.

2. An adjacent wall or floor member (#2) that is perpendicular to the alignment screen can be used as the vertical zero reference. If there is no adjacent wall or floor member that is perpendicular to the screen, tape a second line on the floor perpendicular to both the alignment screen and the first line, and outboard of either side of where the vehicle will be positioned. This will be used as the vertical zero reference.

3. Position the vehicle so that the side of the vehicle is parallel to the vertical zero reference, and so that the front of the lamp lenses are in the vertical plane of the parallel line taped on the floor 7.62 meters (25 feet) away from the screen.

4. Rock the vehicle side-to-side three times to allow the suspension to stabilize.

5. Jounce the front suspension three times by pushing downward on the front bumper and releasing.

6. Measure the distance between the optical center of one of the lamps being aimed (head or fog) and the floor (horizontal zero reference). Transfer this measurement to the alignment screen with a piece of tape placed horizontally to the floor. This line (#6) will be used as the lamp horizontal reference.

7. Measure the distance between the vertical zero reference and the optical center of the nearest lamp being aimed (head or fog). Transfer this measurement to the alignment screen with a piece of tape placed vertically across the appropriate (head or fog) lamp horizontal reference (#7). This is the centerline reference for the first lamp.

8. Measure the distance on center between the first and the second lamp being aimed. Transfer this measurement to the alignment screen with a second piece of tape placed vertically across the appropriate (head or fog) lamp horizontal reference (#8). This is the centerline reference for the second lamp.

================================================== =======

III. Headlight Alignment

NOTE: Due to the linear nature of the headlamp cutoff, a properly aimed low beam headlamp will project the top edge of the high intensity pattern on the alignment screen from the horizontal line to 50 millimeters (2 inches) below the horizontal line for domestic market vehicles, or to 125 millimeters (5 inches) below the horizontal line for export market vehicles. No horizontal (right/left) adjustment is required for this headlamp beam pattern in domestic market vehicles. Export market* vehicles have a second horizontal (right/left) adjustment screw provided. The high beam pattern will be correct when the low beams are properly aimed.

NOTE: For those who wish to adjust their headlights horizontally, you will need to purchase and install Mopar P/N 55078114AA Screw, headlamp horizontal (x2; one per headlight).



Installation synopsis (per rick92f):

Quote:
Remove the grille and headlight assembly. Carefully remove the black headlamp ring/bucket by pulling straight out. Unscrew the pivot stud, thread in the new adjustment screw, push the ring back on, and put the light back in.
1. Turn the headlamps ON and select the LOW beams for vehicles in all markets.



2. On all vehicles except those with headlamp leveling, use a T15 Torx bit driver/screwdriver to rotate the headlamp vertical adjustment screw (1) on each headlamp to adjust the beam height as required.



3. For export markets only,* use a T15 Torx bit driver/screwdriver to rotate the headlamp horizontal adjustment screw (2) on each headlamp to adjust the beam right or left as required.

* unless you have installed Mopar P/N 55078114AA Screw, headlamp horizontal

================================================== =======

IV. Foglight Alignment

NOTE: A properly aimed front fog lamp will project a pattern on the alignment screen 100 millimeters (4 inches) below the fog lamp centerline and straight ahead of the lamp.

1. Turn the fog lamps ON.



2. Insert a T15 Torx bit driver/screwdriver through the clearance hole in the underside of the front bumper (#1) to rotate the vertical adjustment screw (#2) on each fog lamp to adjust the beam height as required.

This information contained in this thread can be found throughout several forums and threads. I thought I would do us a favor and compile it into one thread for future reference.

The information is also derived from the 2014 Jeep Wrangler service manual.

You may also download a .pdf version by clicking [HERE].

Thank you to OP for this great info!

Been thinking of putting on the KC Hilites (#42321), and was worried about how to adjust them so I'm not blinding anyone. I'll be referring to this thread immediately after I install them.

Can someone elaborate how to do this:

As I posted in another thread, the headlap ring seems to be attached in place in three places, and a rather firm pull does not dislodge it. I am concerned that if I pull any harder I will break something and/or strip threads in the plastic. More specifically, the adjustment screw needs to go in the position circled in red below, but there are two other attachment points circled in white. Any ideas? I have everything pulled apart, trying to avoid assembling it before dark tonight then having to pull it apart again to install the horizontal adjustment screws

Be careful... the 3 tabs that hold the alignment screws in place will break.. Someone had luck unscrewing them first... and once the ring was off they were able to pull them out.. It's tedious but if you break it you have to buy an entire new headlight just for the ring.

I'll take a look at it today (08/31) when I install the JW Speakers in my new Jeep.

Try this thread:
Headlight horizontal adjustment


Let me know if it works. I'll ask mod to update this thread.

I have an idea. Can you totally unscrew the Torx aiming screw from the ring. Once you have done that, can you grab the two non-Torx screws (bottom left and bottom right circle) with a Vise grip and then pull each Vise grip straight out at the same time? Is there enough head on those non-Torx screws to bite?

Came to the same conclusions the hard way - broke one of them and had to buy the entire assembly. This is definitely not a job for the weekend warrior. Fortunately eBay and Amazon sell the entire assembly for around $45 vs the ridiculous $180 that the stealership wants. When I first got the price from the stealership I was going to drive to a local U-pull yard, since this part is likely the same on all JKs. The question is whether there are any totaled JKs to pull from.

Does not have any level of detail how to do this correctly.

Nope can't do. The Torx screw goes in more than 1" into the ring. There is no clearance to do that with the studs still in place. You have to be unscrewing the studs and the Torx in parallel, a bit at a time for each. Tedious as hell. Fortunately I broke only one of the rings so I am out of $45. Fortunately I bought my Cibies from Amazon at 1/2 the cost of what they are offered elsewhere, so even after that I am still around $45 ahead. I guess I can break the other one too :-)
