head lights

The horizontal adjustment screw (2) is located on the rear middle edge of each of the headlamp assemblies, toward the center of the vehicle. The vertical adjustment screw (1) is located on the rear upper edge of each of the headlamp assemblies, toward the outboard side of the vehicle.

I think I need to aim my headlights (down )how do I do this?

Before removing the headlamp bulb or disturbing the headlamp in any way, note the current settings in order to ease headlamp adjustment upon reassembly. If the high or low beam setting of the old lamp still works, this can be done using the wall of a garage or a building: Park the vehicle on a level surface, with the fuel tank about 1 / 2 full and with the vehicle empty of all extra cargo (unless normally carried). The vehicle should be facing a wall which is no less than 6 feet (1.8m) high and 12 feet (3.7m) wide. The front of the vehicle should be about 25 feet from the wall. If neither beam on one side is working, and if another like-sized vehicle is available, park the second one in the exact spot where the vehicle was and mark the beams using the same-side light. Then switch the vehicles so the one to be aimed is back in the original spot. It must be parked no closer to or farther away from the wall than the second vehicle. Perform any necessary repairs, but make sure the vehicle is not moved, or is returned to the exact spot from which the lights were marked. Turn the headlamps ON and adjust the beams to match the marks on the wall. Have the headlamp adjustment checked as soon as possible by a reputable repair shop.

Hi,

I was driving my car the other night and it was very hard to see...it seems like the head lights are pointing towards the middle of the lane, so we want to adjust them.

The only switch we can find to adjust is the up and down...does anyone know where the sideways adjustment would be done at on a 99 Pontiac Grand Prix.

Thanks for any help you can give us.

I have added a picture the vertical adjustment screw (1) is located on the rear upper edge of each of the headlamp assemblies, toward the outboard side of the vehicle....Just pull up to a wall about 20 to 25 feet away and adjust them where you want them...

Hope this helps... Cly
