How To Easily Adjust Your Headlights & Fog Lights - DIY Guide

[@hunterdan2002]

The best tutorial I've seen on aiming headlights. Was not aware of the vol or vor.

[@xil3ntkha0s]

Very informative. This needs to be shared to everyone that has a car. So tired of being blinded by those factory LED headlights.

[@LostInPhilly89]

Agreed. The factory setup that Audi uses is especially bad.

[@Briebabcock8052]

Not just led headlights, but halogen users as well.

This was the alignment description I was hoping for. Caesar sent me this link. I just got my rebuilt lights back from Lightwerkz the day after Thanksgiving 2024, I immediately installed them. 😮 I am blown away. My ‘02 BMW e53 can be driven at night now. I feel like I’m driving a new suv now. 😀

This is by far the best video about adjusting the cut off pattern that I’ve seen for 4Runners. Props to you for your vids and your products that you sell.

[@LightwerkzGlobal]

Thanks for your support Mark !

[@sean.g4516]

What if the L L shape part of the beams are stacked on top of each other? I'm thinking they need adjusted left to right ​@@LightwerkzGlobal

[@LightwerkzGlobal]

@@sean.g4516 That means they are too tightly centered. So you want to make sure you spread them out and keep them nice and straight in relation to the distance between the two headlights.

[@sean.g4516]

[@THEE_BRZRKR]

Best headlight alignment video on KZbin so far, but I really wish you would've showed how you measure and transfer your marks/tape to the wall for your vertical and horizontal reference points. Like, how do you get them centered with the marks on the lenses, when the vehicle is 25 feet away and there isn't a wall to the side, parallel with the vehicle that you can measure off of to the marks on the lenses and then measure to the reference points on the wall and make a center point that's the same for the vehicle and the wall? Also, why didn't you show how to align the lights horizontally? That's just as important as vertical alignment. Anyway, I'm not bashing. You guys are doing great things in the headlight community. I was just hoping that I had finally found the perfect headlight alignment tutorial that explained EVERYTHING!

[@achtung6]

Thank you for making this video. I used it tonight to align the stock headlights on the ‘21 4Runner. I was getting flashed by oncoming vehicles after installing the Wescott lift.

BEST video I have found on how to adjust headlights. I didn't know much about it, and I feel you went into detail on the wall on what to look for when adjusting them.

[@lawnchair4]

Thanks for the detailed and thoughtful overview - leveling my new retrofit kit lights purchased from you for my LX470. Highly recommend to others thinking about upgrading their halogens in a professional way.

[@michaelwtm]

I consider this the definitive video for adjusting the headlights on any US car, primarily for the beam pattern drop measurements given that can be applied to any vehicle (4:59, 5:30). Was not aware of the VOL vs VOR thing at all until this video. I have a 2021 Honda Ridgeline. Factory headlight aiming specs call for the beam to be straight ahead with no drop at 25 feet, which is just flat out wrong. I used the measurements given in this video to stop my headlights blinding the mess out of people as I drive down the road.

[@patriotfighter331]

Best video I've found so far on HL adjustment. The VOL/VOR is something i have not heard of either, even on the morimoto page.

[@stoker20]

Thanks for the informative video! For other viewers, If your Phillips bit jambs up on your vehicle you may need a Torx. As far as aiming, if you have powerful bulbs, it's pretty easy to see if your lights are shining in someones' windshield. Big 4x4 trucks are the worst at being D/heads with the aiming. Guess I'm stupid for trying to keep the light on the road?

[@edreeves7697]

Had to try a few different Phillips head screwdrivers to find one that would work with the wheel adjuster. Super easy. Took five minutes.

Awesome video and well explained!

[@dhtsoaedsdhtnadi9575]

CLOSE!!! OH SO CLOSE. IIHS has a research paper on this subject and your measurements are the closest approximation to their data I've seen in ANY aiming video. For those that want more precision... Back the car 25' away from the wall. The first number of each line is headlight height in inches, the second number is drop in inches. If you have projectors with a cutoff and no VOR or VOL label, 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. If you're aiming separate reflector high-beams, measure at the center of the "hotspot". Best to use bulbs with a 4800K-5500K color temp. This closely approximates sunlight on a clear day. Save the ambers for fog lamps, and aim their cutoff to cover the lower third of the headlight beam on the wall. Avoid installing violent blues. 22 - 1.5 24 -1.75 26 - 2 (this is where most headlamps USED to sit and why the old rule of thumb most still cling to worked until minivans, SUVs, and lift kits) 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 All of these aim the light at a point 25 cm (10 inches) above a theoretical plane 100 meters (330 feet) out from the headlights. Everyone can see, even in pouring rain, and oncoming drivers don't complain of glare in any weather, even compacts facing SUVs.

[@usavtwin2003]

@@usavtwin2003 i've never had good experience posting url in comments. try google "iihs headlight test and rating protocol". the table i typed out is what i worked out from page 5 (25cm above) and page 9 (100m out). you'll see that the driver's side and high-beams aim different distances out (60m for driver side, 150m for highs) which make for different drops, which are simplified in my table.

[@dsnewman866]

This is a very informative video. Never knew about the VOL/VOR. I have the Morimoto XB Gen 2 on my lifted 4Runner. I actually just installed them and had aimed them using the top of the right (VOR) before I knew about the VOL and that the Morimotos are VOL. I have, however, accounted for the 3" rule as my lights center are sitting at 44". So, this means I actually have them sitting too low. My concern though is that they already seem quite bright and high enough. If I aim them correctly using VOL, I'm afraid they'll be aimed too high and may blind others. Do you get flashed with them aimed using VOL?

[@vberry2415]

The worst headlights I have seen and noticed for blinding oncoming traffic are the later model Ford F series. The stack area is about 3 stories high, and many are lifted. Just awful design. Overkill, and most don't seem to be adjusted - especially the lifted ones. They all need to see this video!

[@jps2308]

Guys with lifted trucks are the most idiot ones on the road they never adjust headlight aim. I also have a lifted truck, but I guarantee my headlights don’t blind anybody.

[@jjejfd25]

Great explanation and concise and clear. Thank you! I have the Morimoto XB on my Mustang. Has a horizontal adjuster as well. Any instructional video on that?

[@LightwerkzGlobal]

Generally speaking, you just want to "center" those out. Slight inward pitch on the drivers side toward passenger isn't a bad idea but its just a degree or two.

[@joshjohnson9655]

Thanks for the advice!

[@darkboy1759]

How should projector headlights be aimed horizontally? Should the high part of the cutoff land in your lane down the road or should that high side land on the sidewalk?

[@LightwerkzGlobal]

Great question! We didnt go over horizontal alignment in this video for a few reasons. A lot of lights do not have horizontal adjusters built into the design. If they are integrated, they are generally capped off / covered. For this reason when building custom headlights, its very importnat to perform a test to make sure the projector is leveled properly on the horizontal plane. To answer your question though, the high part of the cutoff should be in the lane that the car is driving in.

[@robngyp]

Good video, very informative. The figures you give for distancing etc, are they the same for vehicles in the UK? I for one work in metric millimetres, centimetres and metres.

[@LightwerkzGlobal]

Your laws may have you aim lights differently. However, you will want to convert from inches to centimeters.

[@ardcifliku]

Very detailed video. I'm looking all over the internet to see if someone posted how to aim the 2017 chevy silverado headlights horizontally( left or right)..I know that oem silverado headlights have 2 adjustment screws on each headlight one for up and down and another for left or right ,but I have no clue what are the measurements. Please share if you know how to do that.thank you.

[@LightwerkzGlobal]

Generally speaking should not have to align the lights left/right. In fact most headlights in the US do not have adjusters for it, if they do they are capped off. The measurement is as simple as measuring the distance between the lights on the vehicle. Use the small aiming dots. Then at 25' you will want to make sure the center of the beam is the same distance.

[@spydermonkey2127]

Informative. Although where does that little center point come into play?

[@LightwerkzGlobal]

The mark on the lens is your point for measurement from the ground up to the lens.

[@seniorxj2931]

Love the Vessel screwdriver!

[@pnojazz]

Can you adjust headlights horizontally? My lights are shining in the trees on the right side.

[@LightwerkzGlobal]

ON most assemblies you can but sometimes you have to remove a cap. Are you sure your bulb is seated properly?

[@pnojazz]

Yes, the bulb is vertical

[@a8f235]

I live in europe and have no VOL or VOR writing on my headlights, and no dots on the center or any of that. It's a 2016 Skoda Octavia Scout stationwagon with bi xenon lights where one bulb is both low and high beam.

What is the best colour for foglights for a car like Corolla, Camry, Premio, etc during a misty night drive? White LED bulb or yellow?

[@xrosnero]

how about the left and right alignment? how will you know if its aligned? is the "step up" portion of the beam pattern should be the one aligned to the "dot center" of each headlight?

[@McR45]

DO you experience a black spot with that zig zag ( I don't know what to call that in the cut off) I've had these lights on for about 6 months and the height is adjusted but that spot is awful . Even tried left and right, but nothing helps. Any input you may have would be awesome. If I adjust them up it gets rid of it only because the light just bleeds off in the distance, but everyone is now blinded works for me but not everyone else.

[@Ggg-l6r8e]

Likely the issue is aftermarket housings with aftermarket bulbs. Should not have any dead spots with OEM housings and quality bulbs.

is this adjustment screw changing the height of the shutter? or just the tilt of the light assembly in the housing. My low beams are to high and my highbeams are too low =[

Adjustment screw adjusts the whole internal frame/bracket that the low and high beams are located on. They are generally in a fixed position and not independently adjustable.

I have the Morimoto XB Hybrid and the circle isn't in the centre of the low beam projector. Do you still go off that circle? It's just below the low beam and at the top of the turn signal.

What would be the reason why one of led projectors ( right side) gives off a double beam? The bulb is at the 9 o'clock and 3 o'clock position. The beam pattern seems to be in a vertical arch, that faces left.

[@LightwerkzGlobal]

LED projectors don't use bulbs. You are using LED bulb in a halogen projector? Could be the bulb is not seated properly and its on an angle. Something is off.

[@804MRMAN]

@@LightwerkzGlobal It's a lense specifically for Led bulbs or Halogen. Like HID lenses are made for HID bulbs.

[@804MRMAN]

@@LightwerkzGlobal Thanks. I was actually outside adjusting the bulb 💡 when I made the first comment, and you are correct, a slight clicking of the adjustable base fixed it.

[@LightwerkzGlobal]

@@804MRMAN Unfortunately there is no such thing. Projectors are made for halogen or HID. Projectors don't do that great with plug and play LED bulbs. Especially if its aftermarket projector. Stick with plug and play HID for the best results on projectors. Other than that, I would just check the seating of the bulb and swap bulbs between sides. If issue persists it could be a problem with the projector.

[@804MRMAN]

@LightwerkzGlobal Seems to be a miscommunication. The "lense" is made for LED lighting from a 2020 Lexus RX350. The projectors were used to retrofit another pair of headlights for a 2nd gen gs300, they now accept LED or Halogen bulbs. Lexus uses a circuit board/ribbon with a reflector to emit the led beam. I hope that makes sense now.

Shouldn't require it but if it does those lights are able to be adjusted left/right. Simply measure the distance between the dots on the low beam side of the headlight lens, and at 25' you will want that same measurement on the wall.

We use VOL method when aiming retrofitted headlights. Most of the steps/slopes are pretty aggressive on aftermarket projectors.

@@AngelGarcia-fm1su for the stage series driving lights it’s not that important to do any sort of measurements. Turn on your low beams and then turn on the bar. You want to center the light output just at the low beam cutoff. This way you have light above the cutoff which aids in distance and additional high beam output.

[@zacmich6472]

Hello, should the left and right beam's hotspots unite into one in the distance and if so after what distance?

Not necessarily. If they merge at a distance you can see that means they are completely crossing over at a longer distance. You are basically pointing them straight. I like to point the drivers side inward just a bit to make sure it doesnt cross into the other lane.

Man I love my morimoto hid kits but those headlamps have a super fuzzy cutoff and are probably over $1000. They should be razor sharp like my retrofits

They are sharp individually, the issue is you are bringing 3 projectors together and trying to create a single cutoff at any given distance, its just not possible. On the road its completely fine and you dont even notice. Lets face it, some bleed over is more helpful than hurtful.

Shouldn't require any adjustments. Most of the lights either have capped off horizontal adjusters or they are not even there. However if needed, center them off on the wall the same distance they are apart on the vehicle.
