Wouldn’t u want the headlights at the exact same spot rather than passenger being higher and driver lower to not blind people. I just don’t want my projector headlights even so that at different angles it looks the same and not brighter than the other one. From factory, are the headlights even or one higher than the other like u guys said to do?

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........

[@dancahill9122]

The blinding that everyone has experienced the last few years is caused by the Type of lights the automakers have been allowed to use, NOT the adjustment of the lights.

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!!!”

[@jesusnieto8007]

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.

Shit video

[@dhtsoaedsdhtnadi9575]

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.

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!

[@Ottonic6]

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.

[@yves9893]

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.

[@Ken-zl1jf]

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!

[@kfdaddy]

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.

[@MojoPup]

Best headlight adjustment video I've seen!

[@KO-pk7df]

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 KZbin 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.

With reflector housing people say you can’t use LEDs and you can you just have to re adjust the headlights to the new bulbs

[@SMOKEATER850]

@@ryans413this was true a year or two ago, but you can use LED as long as they have the correct beam pattern, most modern LED bulbs have an adjustable base so it's not really an issue any more. Its HID that shouldn't go into regular reflectors. You'll see better with HID bulbs, but you'll be emitting tons of glare and blind oncoming traffic. HID bulbs should be in projectors, LED bulbs perform poorly behind a projector, so for the most part, a standard reflector is the only sensible option for an LED bulb. I recently heard these 4 sided LED bulbs do well in projectors but have not tried them because the 55w HID bulbs I'm running are amazing.

What’s interesting is I’ve noticed when replacing a headlight bulb, if it’s not seated perfectly, the beam will be off. Just replacing a bulb should not change the position of the beam. This was something I noticed and wonder how many people have poor beam position simply because the lamp isn’t installed right.

[@chilledoutpaul]

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

[@stephenhagen234]

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!

If your driveway slopes away from the garage door (and if it doesn't, you've probably got water issues in your garage), just use a water level to mark a line on the garage door at the exact height of the dot in your headlight. Mine drops several inches over the 25 foot distance. Doesn't make a lot of sense to worry about tire pressure and what you've got in your trunk if you don't level your reference line to your headlight.

Nice video, thanks for educating myself and the masses! I recently gave up on my yellowed lenses and continuous polishing, so my aim could well be off. I wanted to learn, not so much "how" to adjust but rather the specifications to at least "aim" for. I wish police would have a way to enforce and judges heavily fine those who have no concern for others. As one ages, the visual purple in their eyes is not as responsive to changes in intensity of light and the irises to not close to compensate quickly enough. They get the spots before their eyes that everyone is familiar with and recover to see in darker situations much more slowly. Throw in a road hazard like a car without tail lights, a black cow or feral hog and you have a great potential for somebody getting badly hurt and property damage while the fellow with misaligned lights goes on, never seeing the results of his misdeed to humanity. It happens. Realize also that some medications tend to dilate the eyes (marijuana for example), some health issues affect the iris, and I used to get migraines of varying degrees, like many others, and the light can actually be painful. Often these would occur on my way home from work at night. Anyone who believes I am being "holier than thou" or a "stick in the mud", arrogant or whatever please understand this how most thinking and decent people feel. If you are not among the "decent" people you may be offended by this writing. It is OK to be offended we all are at one time or another and there is no civil nor God given "right" to not be offended. I am offended by some people's bright and misaligned lights so this is all I can do and I choose not to be angry, rather hopefully enlightening.

You don’t get it the distance is for proper adjustment. What you want is like leveling a 16’ board with a 6” torpedo level

[@William1866]

@@ArbitraryLifestyle Use math. A 4 inch drop at 25 ft translates to 3.2 inches at 20 ft, 2.4 inches a 15 ft, 1.6 inches at 10 ft, and 0.8 inches at 5 ft. To find the 2 inch drop just cut the inches in half (1.6, 1.2, 0.8, 0.4) Keep in mind the decimal is in 10ths but inches are divided into 16ths so you will have to multiply the decimal by 1.6 to find how many 16ths of an inch it is, but you are going to lose accuracy the closer you get so disregard all of this and do it at 25 ft.
