1. Remove the headlamp trim panel (grille panel) attaching screws.
   
2. Remove the four headlamp bulb retaining screws. These are the screws which hold the retaining ring for the bulb to the front of the car. Do not touch the two headlamp aiming screws, at the top and side of the retaining ring, or the headlamp aim will have to be readjusted.
   
3. Pull the bulb and ring forward and separate them. Unplug the electrical connector from the rear of the bulb.
   
4. Plug the new bulb into the electrical connector. Install the bulb into the retaining ring and install the ring and bulb. Install the trim panel

   To install:
   
8. Attach the headlight electrical connector.
9. Position the retaining ring and install the screws securing the ring to the headlight.
10. Position the bezel in place on the headlight assembly.
11. Install the screws on each side of the bezel and tighten to 51 inch lbs. (5.8 Nm).
12. Install the screws on the front of the bezel and tighten to 17 inch lbs. (1.9 Nm).
13. Cycle the headlamps, then close the hood. Check the headlight aim, and adjust if necessary.

two screws on each headlight control the direction the headlights are aimed. One screw, usually at the top but sometimes below the headlight, adjusts the headlight up and down. The other screw, located to one side, controls the headlight from right to left. Turning the appropriate screw one direction or the other will change the direction the headlight points.
In order to aim your headlights you need to have a flat vertical surface you can aim your headlights at in front of a level surface on which to park the car. If your driveway is level your garage door is the perfect place to aim your headlights.
The tools you will need for this job are simple. Masking tape is used to mark where the headlights are to be aimed and a screwdriver is needed to adjust the headlights. A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks

A tape measure will be necessary to measure the distance of the vehicle to the surface you're using to check the aim and to measure the up and down distances from your marks.
To start you will want to pull your car quite close to the surface you are using to aim your headlights. This is done to allow you to mark, with the masking tape, where the headlights are on the car. With the car right up against the vertical surface, and your low beam headlights on, the center of the beams will be directly in front of the headlights. Use your masking tape to mark straight across where the headlights are shining. Use short pieces of masking tape to mark vertically the center of the low beams.
, back your car about 25 feet away to check the alignment of the headlights. The brightest spot on your low beams should be about two inches below the masking tape and slightly to the right of the vertical marks. Use the adjustment screws to move the beams up and down, and right and left, until the headlights are aimed properly.
If your car only has two headlights, that's all you need to do. With the high beam lights integrated into the single headlight there is no further adjustment possible. If you have a four-headlight system you will next need to adjust your high beams. Switch to your high beams and adjust them so they shine just below the line and are centered between your two vertical marks.

good luck

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
