How to Adjust the Headlights on a Ford Super Dutyby Matt Scheer
If the headlights on your Ford Super Duty Truck, such as the Ford F-550, are blaring into the night sky or blinding the eyes of oncoming traffic, you may have to readjust them. Fortunately, Ford designed the headlight assemblies so that adjusting the beams is a simple and straightforward process. Two adjustment screws direct the horizontal and vertical aim of the bulbs. Turning these aims the headlight. The screws are visible and no extraneous parts need to be removed to access them.
Park your Ford Super Duty truck directly in front of a garage door or other flat, vertical surface.
Measure the height from the ground to the horizontal center of the headlights and place a horizontal strip of tape on the wall in front of each headlight at this same height.
Place a vertical strip of tape on the wall in front of the vertical center of each headlight, creating a cross shape that can be used as a target for aiming the headlights.
Measure 25 feet away from the garage door or wall and place a strip of tape on the ground to mark that spot. Reverse the Ford Super Duty truck until the headlights are directly above that spot, turn on the headlights, and prop open the hood.
Look for the hex bolt on top of the headlight assembly that controls the vertical direction of the headlight beams and the bolt on the back that controls the lateral direction. Adjust these bolts until the high-intensity portion of the beams hits 2 inches below and to the right of the center of the tape targets on the wall, ensuring that the beams illuminate the road and street signs.
