How Should Headlights Be Aimed Correctly on 1990 Acura Legend to Avoid Blinding Oncoming Drivers and Ensure Safety?

The headlights must be aimed correctly to avoid blinding oncoming drivers, which can lead to serious accidents or impair visibility. It is important to check the aim every 12 months and whenever a new headlight is installed or front-end body work is done. The following procedure provides a temporary adjustment until a professional can make the necessary changes. Headlights feature spring-loaded adjusting screws for vertical and horizontal movement. A simple method involves using a blank wall 25 feet in front of the vehicle and a level floor. Vertical masking tape should be placed on the wall to align with the vehicle's centerline and the centerlines of both headlights, along with a horizontal tape line for reference. Ensure the vehicle is level, with a half-full gas tank and no heavy load. For low beam adjustment, position the high-intensity zone two inches below the horizontal line and two inches to the right of the headlight vertical line, using the vertical screw for height and the horizontal screw for left or right movement. With high beams on, the high-intensity zone should be centered just below the horizontal line. It may not be possible to achieve perfect alignment for both high and low beams, so prioritize low beams for driver safety. Have the headlights professionally adjusted at the earliest opportunity.
