Lincoln BA1Z-13008-C Headlamp Assembly

The Headlamp adjustment screws control up-and-down movement, while left-and-right movement is not adjustable. Several methods exist for adjusting the Headlamps, with the simplest requiring a blank wall 25 feet in front of the vehicle and a level floor. Position masking tape on the wall in relation to the vehicle centerline and the centerlines of both Headlamps. Measure the height of the Headlamp reference marks from the ground and position a horizontal tape line on the wall at the same height. It may be easier to position the tape on the wall with the vehicle parked only a few inches away. Adjustments should be made with the vehicle sitting level, the gas tank half-full, and no unusually heavy load present. Turn on the low beams and adjust the screw to position the high beam so it is two inches below the horizontal line. It is advisable to have the Headlamps adjusted by a dealer service department at the earliest opportunity.
