I was adjusting the headlight, heard a click, now the headlight is WAY TOO HIGH, and won't come back down

Find level ground with a wall. Drive up to the wall and mark where the centre of your headlights are on the wall with a piece of tape. Back up 20 feet and turn your headlights on high beam. Using the adjusting knobs make each light shine directly on the spot. Low beam adjusts itself down and to the left/right (away from oncoming traffic depending on what side of the road you drive on)

Replace light switch assembly. Remenber some switches pull up to flash headlights and press down to change from low to high--press down again goes from high to low.

Do you hear switch click when put on high beams? If not could have gotten out of adjustment

Thank you for using Fixya.

Here's the procedure on how to adjust the headlight of your tacoma.

•1
Find an appropriate area to align your lights. The ground should be almost perfectly, if not perfectly level. There should be a flat vertical wall against which you can shine your lights and clearly see the boundaries of the beams. There must also be enough room for you to park the Tacoma 25 feet back from this wall.
•2
Prepare the vehicle for normal weight and height conditions. Take everything out of the Tacoma except for the items that stay in the vehicle at all times. Fill the gas tank and make sure the engine oil level is full. Fill all of the tires to the PSI you usually use. Finally, make sure there is someone sitting in the driver's seat during the testing and adjusting process.
•3
When it is dark enough to see the headlight beams, park the Tacoma on level ground, 25 feet back from the wall, facing the wall head-on. Leave the engine running and prop open the hood.
•4
Look at the backs of both headlight assemblies. Near the top center corner of each headlight, you'll find a small round cap. Remove these caps to expose 8mm screws. These screws control the horizontal alignment of the headlights.
•5
Look at the backs of the headlights again, checking the bottom outside corners of the headlights. You'll see identical 8mm screws sticking out. These screws control the vertical alignment of the headlights.
•6
Turn on the headlights and shine the beams against the wall.
•7
Use a measuring tape to measure the distance between the ground and the center horizontal line in the plastic lenses of the headlights.
•8
Go to the wall and measure the distance between the ground and the center horizontal line's reflection in the beams of light. If the line on either side is higher on the wall than it is on the Tacoma, the light on that side must be adjusted to point down. If the line is lower on the wall on either side, the light on that side must be adjusted to point up.
•9
Use a 8mm socket wrench to adjust the vertical alignment screws on the headlights, measuring the horizontal lines on the wall as necessary, until the center lines of both beams are exactly as high as they are on the Tacoma.
•10
Use a measuring tape to measure the distance between the two vertical lines in the center of each headlight lens.
•11
Go to the wall and measure the distance between the two vertical center lines' reflections in the beams of light. If they are father apart than they are on the Tacoma, the headlights need to be adjusted toward the center of the vehicle. If they are too close together, the headlights need to be adjusted toward the outside corners of the vehicle.
•12
Use the 8mm socket wrench to adjust the horizontal alignment screws on both headlights, measuring the vertical lines on the wall as needed, until the distance between the lines on the wall is equal to the distance between the lines on the lenses.
•13
Replace the caps on the top headlight adjustment screws and close the hood.

All the best!

The hi beams when activated will have all headlight on. If you have to hold the swith in to keep them on that means the switch will not click into the locking mode to keep them on for you. Once you pull back the lever you should hear a faint click. That will lock the high beams on. Pull it again and the same click will be heard and that releases the high beams to off

Hi, i have no idea if this will help you or not, but, on the 1997 grand cherokee, if you look at the headlight itself, look to the outer edge, over the top ontop of the headlight there is a white allen key hole, not sure on the size, this, basically is the up and down adjuster for the headlight, sorry if it doesn't help but i've just had to adjust mine, and thats where it is, the one towards the radiator is the in and out, it pushes or pulls the headlight offcentre

At the back of the headlight there are screws that adjust up and down and left to right,look carefully as it will be written on the headlight,you will see it stamped into the top of the housing just follow the indicators on the light to adjust it down,and park in front of a wall on a flat surface if possible at night or dusk to see how much youve changed the height,its not difficult to do just look carefully

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.
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

green light on dash is your high beam indicator i suspect the dimmer switch or headlight switch is the problem i would inspect the headlight switch first

there should be some screws at the back of the headlights where they go in u would have to adjust those
