Hello, The dealers have a special set of tools that they use to aim the lamps mechanically. But those are really expensive and the alternative method is listed below for you. It is a little work, but the end result should be worth the effort. Thanks,Bob
The screen method requires an area set up specifically for headlamp aiming.
The area should consist of a level surface large enough to allow for a vehicle and an additional 7.62 m (25 ft) as measured from the face of the headlamps to the aiming screen.
The screen should be a wall or other flat surface at least 1.52 m (5 ft) high by 3.66 m (12 ft) wide with a matte white surface well shaded from extraneous light, and 90 degrees to the floor. The screen should be provided with a permanent vertical reference line 0.61 m (2 ft) from the left edge of the screen, 2 laterally adjustable vertical tapes, and one vertically adjustable horizontal tape.
After the aiming screen has been set up and located, paint or tape a reference line on the floor 15.24 m (50 ft) from the vertical reference line on the screen. This line should be perpendicular to the aiming screen and a mark placed at 7.62 m (25 ft) from the screen.
Important: Do not place a cover directly on the headlamp assembly while the headlamp is ON.
