Every states motor vehicle departments should have a wall that drivers can pull up to with markings so that ANYONE can adjust their own headlights properly. In the past few years there are so many cars out there blinding oncoming drivers........

I wish I had a garage that was 25 feet long, lol

Excellent video, detailed, clear, and concise. Very professional and to the point...not full of 'camera-time' trivia about personal life, or what gramma, grandpa, or his buddies do. Thank You.

Based on IIHS data and some trigonometry, the following chart should serve well. Back the car 25' away from the wall. First number of each line is headlight height in inches, second number is drop in inches. If you have projectors, measure at the HIGH side of the cutoff. If you have reflectors, measure at the top edge of the "hotspot", and drop the driver's side 2" more than the chart says. 22 1.5 24 1.75 26 2 28 2.125 30 2.25 32 2-7/16 34 2-9/16 36 2.75 38 2-7/8 40 3 44 3.25 48 3-5/8 54 4-1/16 IIHS describes 330" as the optimal distance of illumination for low-beams, and the majority of autos sold in the USA do not shine that far. The chart above should allow your low beam to illuminate the road 330' ahead (assuming your lights aren't embarrassed by a birthday candle). Using the high side of the cutoff as your drop guide will allow you to see the 330' distance in low beam while allowing the low side of the cutoff to do its job protecting oncomers from glare. If you're aimed according to the chart and shining into the passenger cabin in front of you, you're either a tall truck tailgating a pregnant rollerskate, or you forgot to turn off your highs. If you have reflectors, dropping the driver's side a little more than the chart says will accomplish the same goal SORTA. I say sorta because reflectors are scatterbeams and will cause SOME glare no matter what you do. I recommend a retrokit to a GOOD QUALITY projector setup. If that retrokit uses HID bulbs, make sure they have a solenoid cutoff to allow you to switch between high and low beam. In any case, try to get 5500K bulbs, or if you run HIDs with 55W ballasts, the next color temp higher.

Never knew the driver side headlight needed to be lower than the passenger. Have not seen any other video that mentions this. This is good to know, thank you.

This is the first video of correct aligment for headlight. This is more professional than most videos I have seen!

I've watched several on KZfaq all day, this is the ONLY one that actually shows it step by step CLEARLY !!!! Thank you so much!!!!!

An excellent video that covers it all in a simple straightforward way and leaves nothing out!

Perfect, thank you for the clear and concise information. I will share with all my friends and family.

I just installed new headlights in a 2003 Subaru Forester and aligned them using this procedure. Used a 55” TV box for creating the light beam map. Was easy, fast and accurate. Thank you for creating this superb video. I’m in your debt. “ATTABOY!!!”

This is absolutely a precise and professional way of aligning headlamps and is not inferior to a headlamp aiming tool.

I wish I could airdrop this video link to every car passing that has one headlight aimed too high 😂 Thank you for the super clear instructions!! Not it makes sense why the left headlight seems lower after service. But after measuring according to your guide, they were still both too low. I also upgraded to brighter bulbs as I was just using OEM bulbs, so hopefully with new bulbs and better alignment, I'll be able to see better at night!

This was worth watching. Other videos on headlight adjustment miss key parts like the passenger light will be higher than the left to elliminate blinding other drivers, and that you need to do this on a level surface. This got my lights finally correct. Thanks!

Thank you so much. I just bought a set LED bulbs to replace a dead pair of halogens and I noticed that the cutoff was a lot higher than before. I did as you advised and I am very happy with the results. My lights are now well bellow the rear window of the cars ahead, nobody has flashed me when coming the other way, and the illumination I get is way better than before. You got a new fan here.

Good job explaining the system set up an showing how to basically adjust. I never heard about adjustment on passenger side higher then driver side but it does make sense. Thankyou sir.

Well I followed your instructions to a T and it worked wonderfully. Thanks a million!

Thank you! Just got new projector headlights on my Trailblazer and driver side is pointed at the ground about 5 ft in front of the truck lol. I'm not mechanically inclined but feel more comfortable doing this myself after watching your video.

Watching these videos help me be prepared to do any repair on my van. Very helpful

Great video and I used my garage door and works great, best instructional video I have ever seen. Thanks.

Really clear and instructive video, thanks!

Perfect and precise instructions 👍. I will share with my f&f about aiming headlights.

Best guide for this on KZfaq. Thanks a ton.

And in states where this is part of the check for Vehicle Safety Inspection for license plate renewal this is very important. The phrase "Watch where you are driving. Keep your eyes on the road" come to mind. You have to see the roadway and conditions in advance to be safe. It's also true, you can 'overdrive' your headlights if the vehicle speed is greater than what you can see in advance to take evasive/precautionary action. All impacted by headlight aim. Thanks for the excellent presentation of this facet of motor vehicle safe operation!

THANK YOU, FOR DEMONSTRATING THIS VERY HELPFUL TUTORIAL!!! AWESOME!!

Thanks for the headlight bulb replacement video for my 2003 Alero,did it in under five minutes!

Thanks. As simple as this sounds your method actually works pretty easy. I remember my 1971 Yamaha Enduro motorcycle had this same method diagramed with instructions in the owner's manual. I must say owner's manuals are not what they used to be.

I was doing this all wrong. I was making the two beams meet in the middle crossing over one another (supposedly to make it easier to see down the road farther) which wasnt working. As soon as its dark outside today you can bet im doing this technique you showed. Thank you for showing this video!!

Followed your video to aim a new set of Auxbeam GX's in my '01 Sebring convertible. Test drove and everything is right on the money. Thanks!

Nice vid. All I did was park behind one of my cars and adjusted the cut off line just below the door mirrors. No more blinding car in front

Excellent tutorial. Thanks!

What a most excellent video. I was just getting ready to take it to our trusty dusty repair shop and came across this video and I'm sure you just saved me a lot of Moola!! Thanks Bro!! 1A Auto will now be my first Stop to Shop!!

Your video is the most informative compared to others on same topic on KZfaq.

I haven't hit 60 yrs old yet and when I entered the auto repair world we had equipment to aim lights as part of our annual vehicle state inspection. I aimed my share. I can't count how many times I wish I had one available

Thank you, that just saved my butt big time. I used my garage door as a reference now I can do this for my friends if need be.

Excellent demo. Thanks for the video. I feel good about leveling my own headlights after this. Since this video addresses vertical adjustments to low beams are there any specifics to the horizontal adjustments? Specifics regarding high beams? Thank you again & merry Christmas!

You guys are great for helping people ☺️

Exactly what I was looking for. Thank you!

Thank you. Appreciate the thought behind the actions. Excellent!

Excellent presentation. Good job. Easy to follow instructions. Thanks. G.Parham

This rally helped me out, thank you so much.

This video very helpful to me thanks sir, you doing great work thanks once again.

Wow best video I've seen on adjusting head lights :-)

Good explaining and showing can u say y its set at that height and is there any info on high beam headlamps also horizontal? Thx appreciate ur vid and info.

Thanks! This is one of the best instructional videos I have seen on the subject matter. Well done.

Your videos are so informative they should appear in every automotive School to teach students You're simply the best

Excellent video guys. Just upgraded my bulbs to the new Philips x-treme Vision Gen 2 and was unimpressed...until i adjusted them. Thank again

So helpful, thanks!

Thanks a lot for the vid. And also for A1 parts , I'm a customer, a happy one thanks a lot .✌

When you were bringing your left headlight down, I would have lowered it to where it was too low, then bring it back up for a better visual. I know that's a little overkill but that;s just my OCD kicking in... Thank you for this, it was very detailed and easy to understand.

Very well explained. Thanks

This was an awesomely educational video, thank you for your time and knowledge !!!

I read somewhere the ideal distance ANY headlight should reach out is 200 feet in front of your vehicle, for your DRIVER SIDE headlight. Using 200 feet is not practical so they settled on 25' as a good practical distance for measuring the drop. The ideal distance for the passenger side, I believe, is 400', but I won't do the numbers on that one since it generally doesn't blind oncoming drivers. If you have an average headlight height of say 32" and you want your beam to reach 200', or 2400", then you have to calculate the proportional drop between 25' or 300", and 200' or 2400". The formula would be as shown below, where you're solving for X, the drop at a distance of 25', or 300" 32"/2400" = X/300", 2400X=9600, X=9600/2400, X=4" drop at 25' distance. An even simpler way to calculate the drop is to take the height of your headlight and multiply by 1/8, or .125. This simplified method is for when the distance is 25 feet to the wall. You can substitute your own headlight height, but the rough numbers are going to be around 4" for an average car.

Exelent video!! great explanation works great for my vehicle 👍 thanks for sharing!!

Thanks so much your video was very helpful in adjusting the headlines on my 2008 Infiniti qx56 ...I was blinding other drivers and I know its dangerous both for them as well as myself...😢..thanks a million.😊😊

Thanks for a great video. You guys are really good at getting to the point while providing both what to do and some background as to why. I've been turning wrenches for quite a long time yet still jump on KZfaq for pointers. Glad I came across your channel. Subscribed. I just replaced the headlamps in both a Buick and a Toyota. I'm going to use my garage door as the aiming board. The precision with which to assess and make adjustments is going to pretty much lost on the Buick, meaning I can pretty much do that one with a little bit of winging because it really doesn't project a horizontal transition line. The Toyota on the other hand is a very distinct horizontal line and I'll stick closer to the book, er uh the video.

Very helpful! Thanks for sharing and taking the time to make this video.

Mines a 2015; pretty much the same. Thank you. Nice voice

Great video thank you..Clear and concise...

Great learning video!! Now only if other drivers would stop high beaming For my LED low beams mine are level and are not aimed high and my light housing is projector type so there's a straight line cut off they learn the hard way when i High Beam them back got the upgraded Halogens in the high beams

Excellent presentation, thank you!

Well done. Thank you.

I have been a (UK mot test assistant) exactly the same thing as your (american) health test. when er do our headlight checks we have to use a beam setter and we do not have to set the o/s down 2". In our beam setter box we have a red line and provided the center of the beam "just where it kicks up" is below the red line the light is set okay, but we are allowed to pass the car provided it does not go more than 1" (2.5cm) below the red line. there is more adjustments that we can also preform with the beam setter

Very nicely done. It was clear and precise. I had No unanswered questions THX

Wonderful video, full of knowledge

Many thanks from the UK 😊

Clear information and directions. Thank You

finally, a proper explanation. I'd still like to know the reference height that HIGH BEAMS should be at.. mine look to be right on top of my low beams' focal point..

Thank you for this video! Very thorough!

clear and to the point. Thanks.

what about side to side do you want to keep the beam width as wide as the gap between headlights?

Excellent video .... thanks...... I will be using the tape on my garage door method to do this....

Excellent video. Thank you!

Hi, Where can I find the adjustable knob for my 2013 Honda CR-V EXL?

I usually adjust both my headlights high left, Youre welcome people. ha Very informative video

Very helpful. Thank you!!

Very good. Thank you

Well done. I have it down now. Thanks for the video. Again "Well Done".

best video and very thanks :)

Lived most of my life in Texas, where car inspections are mandatory and lights get yearly adjustments. Now I live in Oklahoma, where cars never get inspections. When a drivers lights are misaligned, they never gets adjusted unless the driver feels up to it.

Thx guys for useful videos!

Great video! I have one question. If my headlights are marked as 1.3% inclination, for 25 feet it is exactly 4 inches. But if they are marked 1% or 2% the number will be different. Am I thinking right, is this the right way to calculate the inclination? Thank you!

How to adjust both sides headlight beam in centre on road, sir please help me thanks.

What about horizontal adjust ment

Althought this an awesome video I cannot see how most people will be able to find a floor that is perpendicular to the wall that lights are shinning on. IF you are inside a garage AND you have 25 feet plus the car lenght inside then sure, inside walls are perpendicular to the floor BUT if your are in any driveway, a parking lot, and facing any exterior wall then you are screwed because any ground surface around a building has to have a slope, even if minimal so rain moves away from the building. Been searching for a good location for a while and never found one. Still an excellent video and gives me all I need to know.

Very informative

Great job. Thanks

Excellent video. I've book marked your site. If your part sales are handled as complete and professionally as this video I'm sure I'll find satisfied when I come back to purchase parts.

Thank you for this, I knew I was right that my passenger side needed to be higher, I had someone telling me that they needed to be the same height, but that did not make sense to me, I would have blinded oncoming traffic!

Awesome info, thanks!

Awesome thank you only real helpful video on this subject 👍

very nice demo. thanks!

Excellent explanations thanks

Good job. Excellent video.

Great information........now to adjust my headlights

great video. lots of help

I have a 2005 Honda Accord ex coupe I attempted to adjust my headlight but I was not able to the adjustment screws. Please help.

I love these guys!

Beautiful!

Great video - thank you for sharing
