Nearly all UK drivers say headlights are too bright

One of the main reasons people want/need brighter headlights is that there is much more light inside the car from screens. These don't let your eyes adjust to the dark properly. Older cars had dim green lighting for the gauges and even had a knob to adjust the brightness up and down. You could create a very dim interior instead of the huge amount of white light you get with modern cars and the multiple screens.
I'm happy my Tesla does a decent job of having the screen be quite dark at night but the headlights are quite bad with the horizontal cutoff style that only lights the first few feet of horizontal ahead of the car. I need to see those deer and elk on the side of the road, damn it.

I understand that currently this is sort of a collective action problem, but I'm a bit baffled why people ever thought they needed brighter headlights in the first place. In the city, it's so bright that you don't even need headlights to see whatsoever. When cars started automatically dimming the dash via a light sensor, there was actually a period of time where I totally forgot to turn on my headlights because things were so well lit -- even at night -- that I didn't need them whatsoever.
Out in the country, you still don't really need brighter headlights. Other cars' headlights will always be visible and they have reflectors, so it's not as if you'll struggle to spot other cars. The road lines are actually reflective, so it's not as if you'll struggle to see the road lines. And generally speaking out in the country, there won't be pedestrian foot traffic, so it's not as if you need the bright lights for them.
So who are they for? I think broadly people may just not be able to avoid excess unless restricted by the facts of their environment. Allow people a plethora of calories, they'll get too fat. Allow them a plethora of entertainment, they'll drive themselves insane. And somehow .. allow them too many bright lights and they'll all just blind each other.

I don't know about the UK, but out here in France, this is wrong on most counts. Many country roads have no lines, reflective or otherwise. There will be pedestrians walking around. Also, roads are not always in tip-top shape nor clean, so you need light to be able to see.
However, I do agree that maybe extremely bright lights mounted high are a nuisance.
bunderbunder
Same for rural parts of North America, and you also have to worry about animals on the road.
But I find that bright white headlights actually make that second problem worse. The bright white light means your eyes don't adjust as well to the dark, so you can really only see straight ahead. So it's much harder to spot deer standing in the relative gloom along the side of the road than it is with older halogen headlights.

This is also true for Germany, but your ability to see in the dark decreases at some point with increasing brightness, since you don't allow your eyes to get used to the darkness.

But for the truly dark areas, you can turn on your high beams - which you aren't allowed to have on when there's oncoming traffic. Smart / adaptive lighting is another option, lower / yellower light in well lit spaces.

I guess you don't actually drive at night in the countryside then.
You need lights to see where the road is, not where pedestrians might be - on none existent footpaths
mingus88
All cars in the U.S. used the same headlights up until the early 80s. You could literally walk into the auto parts store and buy a headlight to replace yours, regardless of make and model
Somehow we all did ok back then with standard high/low beams from lights which are very dim and warm compared to the harsh white LED lights of today
It seems to me that this is just another example of the arms race of modern cars. You need a big SUV to feel safe on a road full of SUVs and trucks. You need an array of dazzling LEDs to compete with every other car out there. And we all lose.
everdrive
I live in the woods in the northeast US, and also grew up in the 80s-90s in a very rural area and I've owned a number of cars when I was young, some with comically dim lights.
You really don't need the bright lights. You never have. Slow down, look for movement, and use your brights intelligently.
macNchz
Growing up in rural New England it seemed that people were constantly hitting deer with their cars—slowing down is obviously a good idea, but every additional foot of headlight distance certainly helps for spotting the glint of an eyeball on the side of the road.
4MOAisgoodenuf
In a densely wooded area, no. Your sight line is naturally blocked by trees, so a farther throw of light would be wasted
In more open areas it can be quite helpful to have greater throw and flood illumination.
In the American Midwest, being able to spot ice patches or deer on the interstate with your brights is quite helpful.
Normal driving lights have no need for the intensity they have today though
lan321
Slow down is kind of the general tip, but I find it kinda BS. I can drive slowly focusing on the bushes on the way to/from work in bumfuck nowhere, or I can get some beacon of god aux LEDs for cheap and turn night into day.
danw1979
Not to be pedantic but you do need to be able to see pedestrians at night too, who can legally walk on country roads on either side, without reflectors or illumination.
It’s the car drivers responsibility to not mow pedestrians down wherever or whenever they are walking.
redwall_hp
A lot of smaller US cities also have areas with no lighting and worn-out lines, which contrast with brightly lit areas and suddenly you're basically blind if your lights are too dim. Couple that with a wet road, which reduces visibility, and it can be hard to see where to drive.
Then we have pedestrians walking with no sidewalks or crosswalks, because city planning actively hostile to people walking.
barbazoo
I just realized I bet it’s sometimes a speed issue. I don’t need bright lights, maybe because I’m a slow driver.
Drive faster and you have to have brighter lights shining farther into the distance to be able to see at least a couple seconds ahead.
taeric
And, notably, those couple of seconds can be key to seeing far off wildlife that may decide to cross the road.
graemep
I think part of the problem is people drive at the speed limit regardless of conditions. If its dark and wet you really should not drive at the same speed as when its sunny and dry. If you are unfamiliar with a twisty road you need to slow down. If there are more pedestrians around than usual you need to slow down.

I do, and old school yellow high-beams were plenty on a 205 to do 80+mph down b-roads back in the 00's, I would happily go back to that if it meant I could avoid being blinded every ten minutes.
danw1979
I’d be happy with other drivers just turning their main beam off slightly faster than 5 seconds after they have seen me.
lozenge
Well this is why headlights have dipped beam and full beam. The issue is the dipped beam is getting as bright as the full beam used to be, and is mounted higher on the car as well.
Frost1x
It’s not what’s meant by pedestrians but usually you’re also looking for wildlife, like deer, that you could hit.
thedanbob
> And generally speaking out in the country, there won't be pedestrian foot traffic, so it's not as if you need the bright lights for them.
Animals, specifically deer. That said, you can use brights when no other cars are nearby, and when there is a car coming its worth a few seconds of extra risk to not blind the other guy and put him at risk.
ComputerGuru
> its worth a few seconds of extra risk
There really isn’t that much increase; when there’s another driver then you both have the combined the light output of both headlights, coming from two different directions.
Aachen
Despite the "I need this in the sticks" responses here, I think the most common answer is the silent group that didn't ask for it but it just comes with the car. This group is silent anyway, they didn't have the issue/need but also won't complain about the extra light, whereas a few other people did and so you can just make 1 size fits all with no repercussions (besides perhaps selling more replacement lamps)
Tox46
If i may add, they won't complain because the headlights of their cars aren't the ones that are flashing directly at their own face. To them the problem will always be the other's cars having the lights too bright.
htek
Most people don't change the brightness of their lights. This is driven by industry using HID and LED lights that have a higher color temperature than the old lighting. It's really a failure of governmental regulation (or lack thereof, in this case).

Have you actually driven in the country?
Out in the country where I live, some roads are single track with no painted lines, cats eyes or street lights. There is occasional foot traffic, sometimes not wearing reflective gear. There are also animals, and 6" deep potholes that I would rather not hit as well.
arethuza
I live in rural Scotland - a lot of minor roads round here have no markings?
crazygringo
> there won't be pedestrian foot traffic
You think kids aren't running across the street at night out in the country? Chasing a soccer ball?
There are all sorts of things you need to be able to see to avoid. People, deer, fallen branches, large roadkill, garbage cans blown into the road by the wind, the list goes on and on. Not to mention spotting dangerous icy patches at night in the winter.
I take it you don't really drive in country? Which is fine, but it's good to be aware of the many potential hazards.
graemep
> You think kids aren't running across the street at night out in the country? Chasing a soccer ball?
Only in well light areas, usually with a low speed limit too.
> People, deer, fallen branches, large roadkill, garbage cans blown into the road by the wind, the list goes on and on.
Of those only people are at all common, and not on large roads. I have never even seen roadkill large enough to be unsafe to drive over.
I have only once come close to hitting any of these on country roads in the UK. I have been dangerously dazzled by oncoming bright headlights all the time.

>> You think kids aren't running across the street at night out in the country? Chasing a soccer ball?

Not something I've commonly seen when driving, but certainly as a kid out in the country I ran around in the dark near the road.

I've seen all of these multiple times (tbf the trash cans were in the city, not the country) out in upstate NY and rural Indiana and Kentucky. Maybe trees don't drop branches over in the UK, but over in the US that is certainly a hazard to be expected during and after severe weather.
To be clear, I agree that excessively bright running lights and people who can't seem to properly transition between hibeams and lowbeams are problem. I just don't agree with the sentiment from the gp that "[o]ut in the country, you still don't really need brighter headlights."
Taek
I feel the same way in America, I think there should be stricter regulations on how bright a car's headlights are allowed to be for it to be street legal. Wouldn't mind having a cap on blue-light levels in addition.
alistairSH
There are a two things contributing to "headlights too bright" in the US...
First, SUVs are really tall... If you're in a sedan (or worse, a Miata) and get close enough to an oncoming SUV, even well-aimed, legal lights are going to feel bright because they're pointed down at you.
Second, there's a decent sized market for cheap, unapproved HID/LED kits for older cars. They're often not aimed correctly.
Aurornis
> Second, there's a decent sized market for cheap, unapproved HID/LED kits for older cars. They're often not aimed correctly.
This is the biggest problem. Even talk SUV headlights from the factory must meet standards for masking off light and the angles at which they can illuminate.
But when people buy LED retrofit kits and jam them into reflectors not designed for those bulbs, the reflectors don’t mask properly. Light spills everywhere.
I would bet that nearly all of the “headlights are too bright” complaints are coming from people seeing LED retrofit kits.
kubanczyk
Aren't there any checks for that?
In EU most DMV equivalents check headlights yearly to catch illegal illumination envelopes (along with other safety-related aspects, brakes and whatnot).
knome
It would be fantastic if it were possible to dictate a headlight height for standard lights. just because your SUV is twelve feet off the ground doesn't mean the lights need to be positioned there.
fusslo
My 2024 outback has no 'high beams'. My low beams are the same brightness as high beams. The only difference is the field of view. I switch on the high beams on and height of the beam increases, but intensity stays the same.
I feel awful about essentially high-beaming everyone unless the road is flat.
pyr0hu
> Second, there's a decent sized market for cheap, unapproved HID/LED kits for older cars. They're often not aimed correctly.
This, so much this. I'm having no issue with new cars and their LEDs. The aftermarket kits that are installed on 1994 Swifts and Passat B5s are not at all configured properly. They just throw it on the car and "yay i can see more" and sometimes I even think that they are using their high beams. But no, it's just their incorrectly set up lights.
MSFT_Edging
> I'm having no issue with new cars and their LEDs
funny, its the opposite for me. brand new SUVs are by far the worst offenders,
Lalabadie
The rising height of headlights in North America is compounding the issue as well. At this point a good proportion of vehicles have headlights even or higher than the roof on a sedan.
JohnFen
At least in my state, there is a law that restricts the location of headlights to between 22 and 54 inches from the ground. 54 inches is quite tall, though, I think that a lot of cars have roofs that are shorter than 4.5 feet. I'd love to see a much lower upper limit.
I don't think there's a limit to how bright they can be. The law limits the lights to "70 watts", which I believe is intended to limit brightness but misses the mark. I bet the law was passed back when headlights were incandescent.
kubanczyk
I'd go as far as to say that the height is the issue, and it's becoming global (although, yes, US is the leader).
It's ridiculous that an average SUV has headlights higher than an average semi (my own experience) given the latter's breaking distance is much greater.
bayindirh
The maximum brightness is already regulated in US and Europe. US allows a lower brightness level.
Some car manufacturer (Ford?) recalled their cars to fix their cars' headlight settings to match US regulations in the last 6-8 months IIRC.
Also, light temperature has limits. I believe >4000K lights are already road illegal in UK and EU. They are also recently outlawed in my country, but there are many cars with after market 5000K+ bulbs installed. They also don't conform to the geometry of the bulbs these headlights designed to accommodate. They are painful to look at.
What needs to be done is a) Stricter regulation in retrofitting older headlights with newer bulbs b) Regulating the amount of light hitting the oncoming driver somehow. c) Stricter CRI and light temperature regulations for the LED headlights.
I don't want to be blinded from light coming from behind and front constantly at night, too.
mapt
Do we enforce it?
At all?
It isn't just retrofits that are a problem, it's brand new cars.
It's not just about not wanting to be uncomfortably blinded by lasers shooting into your eyes at night. (Lasers well under 3000 lumens!). It's that this kills people. Frequently. It's a form of assault with hundreds of dead victims and thousands of injured victims a year.
Aurornis
The regulations for manufacturers are enforced. There have even been recalls for it.
LED retrofit regulations are not enforced. We should equip safety inspection stations with ways to measure this, but it’s an expensive change to demand they do safety inspections in a dark room when most safety inspection businesses are small shops that don’t have the room or buildings to do it.
mnw21cam
Given how many cars I see on the road with only one headlamp working, we have a long way to go before enforcing anything like this.
bayindirh
I believe so, but I need more evidence in either direction to give it a definitive answer, but why companies recall cars to fix their brightness levels if they are not enforced?
> It's not just about not wanting to be uncomfortably blinded by lasers shooting into your eyes at night.
I mean, being uncomfortably blinded creates the risk of being dead already. I believe I made it clear that it's dangerous.
jonasdegendt
It's much worse in America, in my experience. Much more deviation in cars/sedans/trucks on the road, with different road heights each, and MUCH more custom stuff on top.
I'm in Belgium and headlights don't generally bother me too much, but a month in California recently had me going "no wonder everyone has tints here."
englishrookie
I'm in the Netherlands and I DO find it bad. Probably also has to do with my age (early fifties) - your eyes adjust with more difficulty the older you get, it seems.
phito
I do find it bad in Belgium, mostly on big cars like SUVs. Another reason for me to dislike them. Unfortunately they are getting more and more common.
jghn
There are regulations. The problem is they're easy to game. [1][2]

In the UK it's exacerbated by our narrow roads, constant drizzle, disrepair of our streets and highways and by the fact that it gets dark by 4PM.
nikanj
Usually in USA regulations apply to cars, but everyone drives a light truck that's exempt from regulations ranging from emission to pedestrian safety
daemonologist
I find this problem to be most severe as a pedestrian - when my eyes have adjusted to the darkness (even if I'm carrying a flashlight, it pales in comparison) and a modern car is oncoming, I cannot see _anything_. Out here in the sticks where there are no sidewalks I can either take it on blind faith that the driver has seen and will avoid me, or I can step way off into the ditch (but not everyone has that option).
touristtam
Ooooh so I am not the only one to swear at those blinding headlights? Interestingly (or not), I think there should be a regulated height for the headlights all private cars; I drive a B-segment type of car, and I find all those European SUVs have their headlights right at my shoulder level meaning I will always be subject to be blinded by this type of vehicle vs a similar lower car. That goes for the vans as well.
oldjim798
Desperately we need to reign in car "style" choices like this. Beyond headlights being too bright, lift kits should be banned and tint regulations should be enforced. Same with sound regulations.
Public roads are not race tracks; they are for people.
lan321
What bothers you about tints? I've never bothered to get one since it's illegal where I'm at but the new ones seem pretty cool for cave dwellers who fear the light. They tint well during the day but you can still see at night from what I've seen on friends cars.
ghusto
It's like driving behind a truck or van, you can't see past the (tinted) car in front.
The solution would be to overtake people with tinted windows. Unfortunately, the type of people with tinted windows are exactly the type you shouldn't overtake.
okdood64
> Unfortunately, the type of people with tinted windows are exactly the type you shouldn't overtake.
So every soccer mom SUV?
mtoner23
most aftermarket tints are too dark and dont allow pedestrians to see into the car to see if they going to be hit by the driver. its illegal in most places but cops dont do anything about it.
globular-toast
I could talk about eye contact and how using the road only works if we cooperate but, more than anything, I just find a heavily tinted windscreen to be antisocial. It's like the ultimate form of bullying. Driving around in a killing machine without your victims even being able to see you.
MarcScott
I think this is an area where stricter regulation would be appreciated. Just needs an additional checkbox on the regular MOT forms, and all cars would be compliant within a year.
Additionally, car designers should leave headlights and indicators alone, unless they are making the vehicles safer. The first time I encountered an oncoming car with a horizontal LED strip between the lights, I had no idea what style of vehicle was oncoming.
varispeed
It was a monobrow car.
HPsquared
A lot of this is due to differing heights. There are more tall vehicles with headlights that are high off the ground, which dazzle drivers of regular cars.
Even if the dip angle is the same (1% gradient or so), this can still dazzle most people nearby.
Aachen
Vans and other bigger vehicles, that have the lights mounted higher than usual, are indeed particularly bad, but I don't really want to get into an arms race of taller and taller vehicles just to be able to see at night. Better that the manufacturers just angle it down a bit more if they want to put the lights up that high
lonelyasacloud
Empirically on UK roads it's as much about the car industry getting away with selling vehicles that are too large for our roads i.e. oversized SUV's and trucks, as anything else. The combination of driver's side closer to crown, and higher mounting, mean the light's from these behemoths tend to cast more of their beams into the eye line of anyone coming the other way, particularly in smaller, lower to the ground vehicles.
alias_neo
> tend to cast more of their beams into the eye line of anyone coming the other way, particularly in smaller, lower to the ground vehicles
I don't think this is the main issue.
I drive a compact SUV, it has perfectly reasonable headlights, pointed downwards like you'd expect, with more of a dip towards oncoming traffic, like headlights have been for decades.
Despite being in a somewhat high-ish vehicle, I'm constantly blinded when driving at night by what is typically, low sports cars with headlights that are indistinguishable from high-beams.
I have no idea how manufacturers got away with this, and I hope something is done soon to make sure a mandate for them being fixed comes in new vehicles, and as part of MOT for existing ones.
I'm in my 30s, with perfect eye sight, and typically have no trouble driving at night or low light, or even low visibility, but it terrifies me that one day I might hit someone after being blinded by these idiotically bright head lights.
globular-toast
> I drive a compact SUV, it has perfectly reasonable headlights
How would you know?
xzjis
There are two situations where I have problems with being dazzled by headlights: - low beams on roads that aren't flat, because they shine right into my eyes - the high beams of cars behind me (sometimes close), which reflect in my mirrors but also off my ceiling, my dashboard, etc.
But I don't necessarily have a problem with the headlights just because they're too powerful.
helle253
For the longest time, i thought random drivers were flashing their brights at me all over chicago
only recently did i realize, it was the regular headlight LEDs being shined directly at me as they went over a speedbump
icetank
Have to remind myself every time that the bright headlights would actually make me blind instead of flashing for a second.
I was at a junction the other day, there was some new Audi EV at the other side of the junction and I couldn't see a damn thing. I've got perfect 20/20 vision, never had any form of eye problem ever in my life, and I was completely blinded. I'm convinced if they'd turned the full beams on, I'd have disintegrated.
