Headlight adjustment that has not been asked that is very informative if answered....

With the vertical adjustment knob. I am planning on marking the top of where it is now and counting the turns so I can do the exact same adjustment on the other side.
My question is: Will both headlights still be even. Do they both move exactly the same as with a set of coilovers. 1 turn will lift all corners the same amount. I just want to make sure that 1 full turn means the same for right and left. I know of some situations where they may be different and I will use another method if that is the case.
I am sure very few know the real answer to this so please only comment if you are for sure.
Thanks.

 

don't think the amount of turns is going to be equal on those light adjusters. Just pull up to a wall or garage door and turn until they are 'aligned'

 

Ideally, they should be the same... Thread pitch should be the same, so therefore the movement should be the same...

 

Also I have found a diagram on here that shows the back of the headlight. It shows the vertical adjustment knob and says "clockwise = up and Counterclockwise = down" is this for the knob itself or for the screw driver you are using to adjust it. Because if you turn the screw driver clockwise obviously the knob would turn counterclockwise.

 

nobody, come on guys....

 

Screwdriver takes forever.... For the vertical I used an air ratchet. I think it's an 8MM socket on the back.

 

Most headlights are adjusted with the driver's side light a little lower to protect the vision of oncoming traffic. If you have rasised the vehicle you want to be especially careful with this.

It is not real expensive to have your headlights adjusted by a professional and the rest of us driving on the road with you would dearly appreciate you spending the money.

YMMV

 

How the hell can it take so long. How can you adjust it with any accuracy using an air tool. Not to mention I would be scared to break something using an air tool. I figured I would lower each one about 10 turns or so on the adjustment knob, but from what you are saying I may need to lower it about 500 times or so, WEIRD.

 

Do you all want to chip in on the costs?

 

am i suppose to be ratchiting forever on these things because i haven't seen much movement...

 

^ yea, if your using a ratchet, it could take awhile...i just move them w/ my fingers to adjust them now days.

 

yeah same here.. i found level ground or for the most part. pull up to the garage wall and turned the head lights on only. no fogs... then pop the hood and you can use you hands to do it, there not that tight to use tools... at least not for me. from about 8 feet away you will see two brighter glare points. just make sure that they are in line vertically... thats what i did and now i'm not getting flashed any more. i went about 10 turns. i also took it and drove it around after 5 turns and noticed that it was still not enough, so 5 more turns did it... hope this helps

 

I used a drill with extension bits to adjust, takes a while by hand...

in any case, it doesnt matter if they are the same (theoretically the each rotation will move it the same amount, however starting points will vary), just adjust to your liking.

 

...theory vs. reality... is what may bite you.

In theory, yes, same number of turns should net you the same movement.

Reality, from my experience anyway, is that after a certain number of turns my HLs stopped moving before they got to where I needed them to be. I had to back off the height adjustment a bit, then turn the horizontal adjuster a bit (l then r), then the height would adjust down to where it needed to be. I.e, it seemed to "stick" at a certain spot, then I had to mess with the adjusters before it would move properly again.

I used a flexible extension, a screwdriver bit, and a cordless drill (at slow speed) to adjust mine. Didn't count turns, just got them to where they needed to be.

If you do count turns, I would make sure that you're in front of a wall, as suggested by other posters, then ensure that the HL is moving as you adjust it. If it moves for every turn, you should be good.

I agree that it's unlikely that adjusting the lights the same number of turns will yield the exact same results. The lights probably aren't exactly the same on both sides now anyways.

Just use a white wall. Set one where you want it, and fiddle with the other one until it matches.
