Headlight adjustment How do I adjust my headlights on a 1993 Olds Cutlass Ciera, the drivers side "low" beam is the worst, the high beam is a little better but not a whole lot; they are pointed way too low. Please help.

What is the proper adjustment/
Head light adjusters are part of the head light assembly and yes high and low beam are adjusted as one unit normally. Proper adjustment is done on a machine, at an equipped facility.

HEADLIGHT REMOVAL AND INSTALLATION
SEALED BEAM HEADLIGHTS REMOVAL 1 When replacing the headlight,do not turn the spring-loaded adjusting screws or the headlight aim will be changed 2. Remove the cover over the headlight this vehicle has five screws securing the cover other models may have four or six screws. 3. Remove the four screws which secure the retaining ring around the headlight support the headlight as this is done. 4. Pull the light away, unplug the connector and remove it from the vehicle. INSTALLATION 5. Position the new unit close enough to connect the wires. Make sure the numbers molded into the lens are at the top. 6. Install the retaining ring and mounting screws. 7. Install the plastic cover to the headlights with the screws you took off and check for proper operation. If the adjusting screws (spring - loaded adjusting screws) were not turned, the headlight should not require adjustment.

Just open the hood and remove plug behind headlight and then turn plastic lock ring counter-clockwise. Make sure not to touch the new bulb with your finger`s-the acid on your skin will shorten the life span of the bulb. Bulb should cost you $10-15.

Remove turn signal assembly (uses a torx 15 driver). This will expose the two 10mm bolts on the one side of the headlight assembly. Remove the plastic front grill (uses a torx 15 driver - there are about 6 screws). This will expose the other two 10mm bolts on the headlight assembly. Remove the four 10mm bolts to remove the headlight assembly and this will allow you access to the headlight you need to replace.

MOST VEHICLES HAVE A CIRCUIT BREAKER BUILT IN THE HEADLIGHT SWITCH. OVER TIME THE CIRCUIT BREAKER WILL GET WEAK & IT WILL TURN THE HEADLIGHTS ON & OFF. YOU PROBABLY NEED A NEW SWITCH & THE FUSE BLOWING IN THE TAIL LIGHT CIRCUIT MAY BE A SEPARATE ISSUE.

if you look at the light, there is an adjustment screw at the top of the light that controls the up and down motion , clockwise will raise the beam, and a screw on the side that controls the side to side motion. the best way to center your lights would be to park the vehicle 25 feet away from a verticle wall. be sure to be very square to the wall and on level ground. make a tape line vertically on the wall in very close relation to the center of the vehicle, and another tape line vertically in very close relation to the center of each headlight. now place a tape line horizontally in very close relation to the center of the headlights. start with low beam adjustment. adjust the high intensity zone to 2 inches below the horizontal line and 2 inches to the inside of the vertical line directly in front of the headlight. for high beam adjustment, adjust so that the high intensity zone is centered on the center vertical line and just below the horizontal line. hope this helps

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.

Yes you can. There is an adjustment screw at the top of each head lamp and you just turn them out or counter clockwise and the beam will come down. You may also have to adjust them side to side also. There is an adjustment screw as well.
