Can't find anything about this in search... I just put in an aftermarket replacement headlight assembly. The assembly appears to sit perfectly normally and level, but the light output is aimed really, really low. Pretty much just illuminates the street in front of my bumper. Is there anything I can do to adjust the angle of light output? Both the high and low beam are aimed too low, but are correct relative to each other; with the lights on right in front of a wall, the high beam shines the same distance above the low beam in the aftermarket assembly as it does in the stock assembly. Any help on this would be greatly appreciated.

quoted from www.wjjeeps.com (the bible of WJ's):

Headlamp alignment
A. Vehicle preparation for headlamp alignment

1. Verify the headlamp switch is in the low beam setting.

2. If the vehicle is equipped with a headlamp leveling system, be certain the headlamp leveling switch is in the “0” position (export models only).

3. Correct defective components that could hinder proper headlamp alignment.

4. Verify proper tire inflation.

5. Clean headlamp lenses.

6. Verify that luggage area is loaded as the vehicle is routinely used.

7. Fuel tank should be FULL. Add 6.5 lbs. (2.94 kg) of weight over the fuel tank for each estimated gallon of missing fuel.







B. Alignment screen preparation for headlamp alignment

1. Position vehicle on a level surface perpendicular to a flat wall 32.8 ft (10 meters) away from front of headlamp lens (see figure above).

2. If necessary, tape a line on the floor 32.8 ft (10 meters) away from and parallel to the wall.

3. Place 75 kg in the drivers seat to simulate the ride height of the vehicle when driven.

4. Measure from the floor up 1.27 meters (5 ft) and tape a line on the wall at the centerline of the vehicle. Sight along the centerline of the vehicle (from rear of vehicle forward) to verify accuracy of the line placement.

5. Rock vehicle side-to-side three times to allow suspension to stabilize.

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

7. Measure the distance from the center of headlamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this line for up/down adjustment reference.

8. Place a tape line 130 mm (5.12 in.) below and parallel to the center of headlamp line.

9. Measure distance from the centerline of the vehicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle centerline. Use these lines for left/ right adjustment reference.


C. Headlamp alignment adjustment

To adjust headlamp alignment, rotate alignment screws to achieve the specified low beam hot spot pattern.

A properly aimed low beam headlamp will project a high intensity light pattern on the screen with the horizontal cut-off line aligned with the tape line 5.12 in. (130 mm) below the headlamp centerline. The intersection of the horizontal and 15 degree cut-off lines in the projected pattern should align to the intersection of the headlamp centerline vertical tape line and the tape line 5.12 in. (130 mm) below the headlamp horizontal centerline.

NOTE: The vehicles low beam headlamps must be“ON” during the headlamp alignment procedure. The high beam pattern will be correct when the low beams are aligned properly.

here is a picture of the headlight:

on the top right of the top right image you can see a hole in the crossmember. there is a little torx screw down there that you turn and it will move the headlights up and down.

The large plastic bolt or the small metal one just in front of it?

the long skinny 7mm bolt is NOT an adjustment bolt. that bolt simply holds the headlights in place. the adjustment screw is down in a whole through the crossmember.

in the pic below, the adjustment screw is in the whole that has the 2 black wires coming out of it. yours wont have these wires.

thank you for the response... I actually did manage to figure out how to aim them last night.. and also how to level my hood using the large plastic bolts
