Headlight aiming?

What is the standard procedure for re-aiming headlights after a lift and tires? I assume you park in front of a wall a given distance away and adjust the lights to a given height from the ground. What is the distance from the wall and the distance to the ground. I would assume also that all measurements are taken from centers. It irritates me getting brighted all the time by little piece of crap cars.

If your kidneys don't hurt, it's not a real Jeep!

Re: Headlight aiming?

I hope we get a good answer for this one, I'm in the same boat. I replaced a headlight a while back and aimed it how it said but I still get bright lighted too. I'm running 4" spring and 1" body lifts with 35s.

Re: Headlight aiming?

I adjust mine for the best driving on bright, that may change with the addition or subtraction of a heavy item, like a hardtop. If you are lifted it is likely that some will flip the brights at you. If this bothers you, you can either flip on your bright, off-road lights or swerve toward the centerline. While this may be an unsafe practice it may make you smile.

I'm on here so much, I have carpal tunnel reader syndrone.

Re: Headlight aiming?

Here in Maryland the state inspection shops do that with a headlight adjusting machine when you get your vehicle inspected,[img]/wwwthreads_images/icons/tongue.gif[/img] but it's always to high for my taste (especially in fog) so I go out late at night on little traveled roads, find a nice straight away and get out the proper tools and adjust them a little on high beams, drive down the road a little stop and do it again until I get them where I like them. It works for me I haven't been high beamed since[img]/wwwthreads_images/icons/smile.gif[/img]

Re: Headlight aiming?

Man, I was hoping to get the answer too. I never get brighted even though I have a "coon hunter".

Re: Headlight aiming?

Here's the low down on aiming your headlights. Low beams do not aim straight ahead when aligned. They point down and to the right. This keeps from
blinding oncoming drivers.

High Beams are not named High because of an increased candlepower; they are named High because the beam is aimed higher. High beams aim straight, out
from the headlight when the low beams are correctly adjusted. That's the reason you can be blinded by High beams from oncoming traffic.

Try this solution:

You'll need:
Tape Measure;
Flat wall (I use my garage door!)

Vertical adjustment:

1. Park about 25 feed from the wall on the level!
2. Measure the height of the headlights, at their center.
3. Measure the height of the light beam at its center.
4. Adjust the LOW beam so the center of the beam is about 2" below center of the headlight height.
5. If you have done the adjustment correctly the High Beam should follow, it's locked in.

If you make a two-inch error at 25 feet, the error compounds with distance. It becomes an error of about two feet, 300 feet distant. 300 feet is a point at
which you should be able to view a person.

Horizontal Adjustment:

Repeat steps 1 - 4, only, measure the separation between the headlight centers. The separation of beams, center to center, on the wall should be the same as the headlights.
5. Move the Low Beam about 2 inches to the right.

I think this will get you in the ballpark.

Re: Headlight aiming?

Find the lowest-profile rice-burner(Honda) and lower it just enough to blind the driver. You should be ok with other drivers[img]/wwwthreads_images/icons/wink.gif[/img].
