The headlights should be adjustment made in a right manner to avoid blinding other approaching vehicle or even reducing visibility hence causing severe accidents. The aim should be checked at least once a year and also any time a new headlight is fitted or front end body work is carried out. The following operation gives a temporary relief until one can get a professional to rectify the problem. Horizontal screws are not available, while the vertical adjustment screws are located at the rear part of the headlight housing. One of the uncomplicated ways is to use masking tape, a dead flat wall, and a level floor. Tape directly up from the centerline of the vehicle and the centerlines of both headlights vertically, and also tape horizontally for composure. The car must be parked twenty-five feet away from the wall, in a flat surface with half-tank of its gasoline reserves and no extra load. For low beam adjustment turn the adjusting screw clockwise to raise the low beam and counterclockwise to lower it, and the high-intensity zone should be two inches below the horizontal line. If that is the case, then the low beams should take precedence especially if a compromise is to be made. With the high beams on position the high-intensity zone right in the middle of the vertical just below the horizontal line. Move the car to a dealer or a service station to have the headlights set properly as soon as possible.

Next, remove the four headlight housing bolts, noting the headlamp housing screw locations from the front and side views.
