As a Tesla driver (yeah yeah) I’ve noticed in my heavily-Tesla area that 80% of the time when I think someone might have their highbeams on but it’s borderline that it’s a Tesla. It makes me uncomfortable about how bright my own lights are to others. My only consolation is that my car is 6+ years old, so there’s a (slim) chance that the new cars that are being rolled off the line are more poorly aligned than my own. Anyway I don’t know what I could do about it regardless.
Yeah, I’m so morally bankrupt that I am worried about how my headlights might blind other people. At least I’m not so morally bankrupt that I make other people feel bad on the internet.
Look through the manual to see if there’s a way to adjust the angle of your lights, or take it into a service center to see if they can adjust it. I’ve never owned a Tesla so I can’t speak on that with any certainty, but all the other cars I’ve driven have had relatively easy ways to adjust the headlight angle.
It’s something I have noticed too. 9/10 times an oncoming car is blinding me, it seems to be a Tesla. And not because their high beams are on. It might be confirmation bias, but it just seems like Tesla headlights have dogshit beam control optics on top of having fairly bright light sources.
Nope, not just you. I live in the greater Seattle area (nearly the tesla capital of the world) and 8/10 times I’m blinded is a tesla in oncoming traffic.
Rivians are also terrible, and most crossovers in the last 2-3 years have been increasingly bad.
Driving a lowered sports car with no windshield tint has made driving at night a horrible process. I’m debating getting a low % window tint just to take the edge off of the headlights.
When there’s someone behind me with their brights on, i roll down the window and hold my palm over my left mirror so they can see me blocking the light (it has never worked)
I always try but I don’t think the side ones move that far, and the center mirror has that auto darken thing and rear window is tinted so it’s not that bright
I think in china they have these scary images on backwindows that shine when lights reflect in there for highbeam users
One time on a dark road a pickup truck had super bright lights. I flashed my brights at them to communicate that maybe they had left their brights on. They then proceeded to flash their actual brighter brights at me. Unbelievable lol
So I drive an Old car (Audi 80 build 1994) and it’s so annoying when people behind me drive with an automatic High beam. My front and rear lights aren’t as bright as newer cars so their car detects me way to late and blinds me every time there is no oncoming traffic. Sometimes I then start turning my bright foglight (on the back) on to make thier car think I’m closer.
Automatic high beams are a new hell. I thought people were just retarded until I hired a newer car recently. Then I realised what everyone else was doing… trusting faulty technology, and possibly being lazy in the process.
The AHB on my Tucson works great, until it doesn’t. Usually when theres a few widely spaced cars on a 2 lane country road… Biggest issue is some genius decided to program the module to not let you turn the high beams off in auto mode unless the high beams are on. So when the system is doing dumb shit you have to let it flash people or do a hard reset by turning the lights completely off and back on.
The main issue I see comes from regular headlights being replaced with LEDs and other High-Intensity bulbs. Don’t get me wrong, Bubba with his lift kit is just redneck high-beams, but I get more frequent glare from someone in a Sentra who decided to put LEDs in her stock headlight assembly that wasn’t made for LEDs.
That’s my feeling as well, but it would be great if any data exists. Most of the intentional LEDs may be super tight but also have very sharp cutoffs, no problem
How many of these blinding headlights are
idiots driving with high beams
idiots with aftermarket LEDs that should be illegal
idiots who raised their truck enough that headlights can’t be aligned correctly
I drive a van, so I could easily be the culprit. I therefore make a habit of adjusting my beam dip appropriately. Apparently that is unusual enough for them to note they had been adjusted in the service. There’s literally a dial on the dashboard. You’re SUPPOSED to adjust them to the vehicle and road conditions! Apparently not having them set to max is now considered a “fault” to fix!
If you normally drive the van with a load on the rear axle and it went for a service with nothing in the back, that could explain why they adjusted it higher.
The load varies, though I’ve found the suspension is hard enough that it doesn’t shift for a normal load up. I mostly do it because I’ve noticed that, when I hit a bump, my lights can sweep up over the windows of cars in front.
Also, I don’t mind them readjusting it. It’s calling it a fault that bugged me.
There’s a load of cars with headlights that are overly bright, but there is an even bigger epidemic of idiots driving around with high beams on as part of regular course.
In the city there is no need for those, ever. Let alone always being on.
it’s hard to tell the two apart these days because many cars have regular headlights that are as bright as normal high beams. there have been a few times i’ve been mad at someone behind me with their high beams on, and then they flash their actual high beams because they’re mad at me for not also speeding while blind
god, driving at night used to be so fun, now it’s ruined
I don’t disagree. There are plenty of led upgrade kits that are way too bright regularly and also probably misaligned causing them to be double bad. Brighter than normal and aimed directly into your eyes.
I’m with you though, driving at night used to be a lot different and more enjoyable than it is today with all these extremely bright lights pointed at your eyes.
because many cars have regular headlights that are as bright as normal high beams
You seem to have no grasp of how car headlights work, because almost every single car that has ever been produced has high beams that are as bright as their low beams
I’ve noticed quite the influx of highbeams in recent years. I simply can’t understand why though. Stupids wanting to see better, by making other’s vision worse? Western Canada here, and I thought it was just me taking notice. Fuckn why??
I mean I guess I’m stupid but I straight up can’t see if there’s oncoming traffic and my brights aren’t on. Doesn’t go for every oncoming car (if its lights are reasonable then I have no issues) but the vast majority of cars have newer, hilariously bright headlights that shine in a way where my normal lights simply don’t seem to cut it.
Dude YES. 20 years ago driving in the country you see some high beams in the distance and people would go back to low beams as they get around a corner or crest a hill when they see other cars.
My commute is through a lot of schools and parks and pedestrian crossings and it’s somewhat poorly lit, so everyone has high beams on regardless of traffic but as a result I can’t see shit. If there’s oncoming cars stopped and a pedestrian tries to squeak through I literally wouldn’t be able to tell.
It’s gotten so bad, either people have their brights on all the time or they’re not adjusted properly. In either case headlights DONT HAVE TO BE SO BRIGHT.
Meanwhile I’m out here driving a 20 year old car with correspondingly dim headlights and need to have the highbeams on just to be able to see anything when there’s oncoming traffic. My normal headlights are fine when there’s nothing coming the other way, but that’s not really how that’s supposed to work lol. Kinda defeats the purpose of ever turning the brights off! I swear any newer car’s normal lights are brighter than my brights
I don’t see how running high beams held you see when there is oncoming cars with brighter lights. Maybe it has more to do with the fact that older cars are smaller and lower?
I am not disputing new cars have higher brightness on regular lights, that absolutely is true. Though running high beams throws light both forward and up toward the oncoming drivers eyes.
Unfortunately I don’t know the physics, maybe something to do with how lights scatters through the windshield? Idk, all I can tell you is my repeated experience: turning the brights on definitely helps with seeing through oncoming traffic. But you are right, my older car is both smaller and lower, so I’m sure even the modern cars with lights aimed downward are more likely to shine directly at me
Our problem is not that we drive small cars (I drive a Focus). It’s that newer vehicles are enormous, usually for no reason.
Nearly every time I get on the highway, I’m tailgated by someone in some newer massive SUV where the headlights are at the same height as my rear view mirror. I don’t understand why those vehicles are allowed to operate on the same roads as me. They aren’t safe. By default, stock, out of the factory, they blind the other drivers in reasonable cars. I can’t imagine what getting into a wreck with one would do to my car (and me in it).
Oh, there is a reason, and it’s the fucking NHTSA. Those absolute fuckrockets mandate proportionally stricter emissions standards on smaller cars than larger cars. They base it on the area of the rectangle formed by where the tires touch the pavement.
If your car can’t quite pass emission standards, just make it a little wider, a little longer, and you get a looser standard.
Repeat the process for a few model years, and now 2025 subcompacts are larger than 1995 sedans.
Same, and they might even have properly adjusted headlights, but as soon as they tilt up (e.g. due to a speed bump), the flashing lights make it look like they are sending me a light signal. Usually takes a few seconds until I realise they just hit a speed bump.
You know how solar eclipse glasses allow you to see the sun surface without any glare by essentially reducing the light by like 50,000 times?
You can also point the glasses at a regular light to see the bulb.
I need the same thing that let’s me check really quick if some scrub has their high beams on so I can reflect their blinding light of death back at them because I’m too nice to do the same against morons who threw nuclear bombs into their regular low beam enclosure.
Although I am also very close to buying a rally high beam light array to do the light equivalent of telling people to shut up.
If all LED headlamps followed a new polarization standard, things could be very cool. As an example, let’s say the headlights could only shine horizontally polarized light and the windshields could only pass vertically polarized light. That means that one could see every thing very clearly because you wouldn’t be blinded by the cars coming on the opposite side. Your light would illuminate everything in from of you, which would then reflect non polarized light back at you plus all other light reflections from other sources like street lamps. Houses could be fitted with the same filter film as older cars. Similarly, people could wear polarized glasses and get the same benefit.
I agree with you. Our king Elon tried to make our cars automatic. Our felon president trumpfus will be banning electric cars and orange lights because he doesn’t like to be called orange face.
Yeah but see that would require the government to do something, and right now they can’t even tell their asses from their elbows. Oh and they’re cutting at least half the jobs. Because eFiShAnSeE.
It would add to the price, which would suck, but I’d love to see some sort of HUD assist system. Even if it was a wire frame or something that appears as a HUD on the windshield. Not bright enough to blind you or be in the way, but enough to see. User could adjust the color (within limits to maybe not negate the system). To me, we don’t take enough advantage of HUD tech and different types of vision that a computer could do that a human can’t. Make it come on with the headlights or something. That way it’s not on during the day.
One big challenge with this is that the human eye has not followed all the technological advances… Its still gonna give you shit after the age of 40. So that means you cannot have a simple mirror reflection system where the driver simply focuses on stuff outside of the car and then from time to time onto the HUD. But I think Mamazon and the apple companies have figure either automated focusing or long distance focusing such that the eye doesn’t have to focus on shit up close while driving. So it’s totally doable.
I do have some concerns about polarizing the light. If I can get a hold of some cheap filter material I might be inclined to do some tests. Maybe I can rescue the polarizer out of an old LCD TV.
Polarizing’s not completely magic, It does seriously reduce the amount of light coming in. There’s just usually enough light around that it doesn’t affect us, our pupils dilate a fraction of a fraction and it’s no big deal.
But at night when there’s already relatively little light out, It does reduce the overall light amount.
I’m also concerned that any light that bounces off something but maintains the polarization will be blocked, so there will be a higher chance of you not being able to see some percentage of your own headlight illumination, I would think that the average diffraction off everything in front of you would thoroughly destroy the coalescence of polarization but I don’t really know for sure, it’s possible that would make your own headlights less effective to you.
I suspect if we were thinking about this in the '50s if it were viable somebody would have pulled it off by now. But we only have had windshield sized polarizers in TVs for maybe a decades so maybe?
All I can say is that it works. I’ve tested this using a flashlight and polarized film on the lamp and on my safety glasses. It makes everything evenly lit. Other light sources become useful since you’re not blinded by the incoming light.
I didn’t pay attention in physics class, why is the light reflected back not polarized? what happened to the once polarized photons that they come back non polarized?
Also what is polarization? I know that Electro Magnetic Radiation or EMR is made up from pulsating magnetic and electrical fields that propagate through space at a fixed rate or frequency… but what does polarization mean? does it mean the fields are slanted to one side or into one direction or something? or is it like some sort of spin or other sort of modulation?
There’s Horizontal and vertical polarization as well as circular polarization. In a simple explanation , think of horizontal as a fence with horizontal bars so that only the horizontal part of the photons pass thru. Now once those horizontal photons pass, they will meet surfaces, which will reflect back their light so your eyes can see it. However, in this experiment only the vertical photons will pass your windshield. Because polarization depends on the angle of incidence, you will get some of the horizontally polarized light back as vertically polarized light which will pass thru. The effect is psychedelic. I totally recommend you to try it. You need polarized glasses, a flashlight and a piece of polarized film to place on your flashlight. The colors and shapes come back to you without defined form or glimmers so stuff looks normal, but weird as heck.
I think ‘uncanny’ would fit better, as certain surfaces would fluoresce despite having no apparent source of light, artifacts, or glaring that you could see.
My car’s headlights blind me sometimes when they reflect off road signs. I tried to find warmer replacements, but it seems like that’s just not a thing
The most annoying thing about bright LED headlights is that LEDs don’t have to be bright. Yet because so many are, people view LED headlights as the problem. You can get varying brightness LED bulbs for your home, why not your car?

Since you can’t use your mirror anyway, just adjust it so that it reflects back at them.

Install a rear mounted light bar to blind them back.

Somewhere for me to go and make myself annoyed?
It is like road rage videos. I hate road rage. I hope they lose their license. But I can’t watch them because they pointlessly get me worked up.
Welcome to the Internet

Anything that brain of yours can think of can be found

I know that Electro Magnetic Radiation or EMR is made up from pulsating magnetic and electrical fields that propagate through space at a fixed rate or frequency… but what does polarization mean? does it mean the fields are slanted to one side or into one direction or something? or is it like some sort of spin or other sort of modulation?
There’s Horizontal and vertical polarization as well as circular polarization. In a simple explanation , think of horizontal as a fence with horizontal bars so that only the horizontal part of the photons pass thru. Now once those horizontal photons pass, they will meet surfaces, which will reflect back their light so your eyes can see it. However, in this experiment only the vertical photons will pass your windshield. Because polarization depends on the angle of incidence, you will get some of the horizontally polarized light back as vertically polarized light which will pass thru. The effect is psychedelic. I totally recommend you to try it. You need polarized glasses, a flashlight and a piece of polarized film to place on your flashlight. The colors and shapes come back to you without defined form or glimmers so stuff looks normal, but weird as heck.
I don’t want anything about driving at night to look psychedelic or weird as heck
Its just weird. Once you see it, its just like any other thing in life.
I think ‘uncanny’ would fit better, as certain surfaces would fluoresce despite having no apparent source of light, artifacts, or glaring that you could see.
They don’t have to look like point sources that feel like they are burning your retina.
That’s so oddly specific but I love it
My car’s headlights blind me sometimes when they reflect off road signs. I tried to find warmer replacements, but it seems like that’s just not a thing
Yeah, I guess that’s one part of the problem. It’s not like most people care that much. But if that’s the only replacement lights you can get… :/
The most annoying thing about bright LED headlights is that LEDs don’t have to be bright. Yet because so many are, people view LED headlights as the problem. You can get varying brightness LED bulbs for your home, why not your car?
