How do you adjust headlights on a 1995 Buick Roadmaster?

To adjust the headlights on a 1995 Buick Roadmaster, park the vehicle on a level surface about 25 feet from a wall. Turn on the headlights and locate the adjustment screws, typically found on the headlight assembly—one for vertical and one for horizontal adjustment. Using a Phillips screwdriver, turn the screws until the light beams are level and aligned with the specified height and distance marked on the wall. Make sure to repeat the process for both headlights to ensure proper alignment.
