How do you adjust the headlights in a 2002 Oldsmobile Silhouette?

To adjust the headlights on a 2002 Oldsmobile Silhouette, park the vehicle on a level surface facing a wall about 25 feet away. Open the hood and locate the headlight adjustment screws, usually found on the back or side of the headlight assembly. Use a screwdriver to turn the screws—clockwise to raise the beam and counterclockwise to lower it—until the beams are aligned properly, typically aiming just below the horizontal line of the headlights with the vehicle's front end. Finally, test the headlights to ensure they provide adequate illumination without blinding other drivers.
