I hate these new lights on cars so so much, instant flash bangs. : memes

[–] DeceasedPassenger@lemmy.world 21 points 6 days ago* (last edited 6 days ago)

I relate so hard. Honestly LED's are nothing compared to the fucking laser headlights that now exist in Volvo models and others. Yes, you read that right, actual lasers.

I've been on the receiving end and actually had to pull over for a minute just to survive (ie not crash due to complete blindness from being flasbanged). Laser headlights should be illegal yesterday. The permanent damage from exposure again and again over time is going to cause long-term and slowly emerging vision problems theoughout the population. Seriously.

Its a lot of the lighting going up on buildings next to roadways that are starting to get under my skin. If you're going to use a 300000000000 lumen LED, can you at least not point it directly at an oncoming lane of traffic? Thanks.

Likewise some emergency vehicles have made it difficult to get around an accident safely since you can't see shit.

[–] Xiisadaddy@lemmygrad.ml 13 points 6 days ago (2 children)

I remember reading about how cars in other countries like China, and Europe have LED headlights that will detect where other cars windshields are and turn the LEDs that would shine in that direction off re-actively. But that it was illegal in the US for some reason.

[–] Evil_Shrubbery@lemm.ee 5 points 6 days ago* (last edited 6 days ago) (1 children)

My 10 year old car has that. Just adaptive headlights.

USA legalised them only recently - that's why ("expensive") European cars in Murikan movies always had the shitty incandescent headlights that in most markets weren't even available.

None of us noticed what headlights were used in a movie because we aren't serial killers :(

[–] Xiisadaddy@lemmygrad.ml 4 points 6 days ago (1 children)

This sounds like something a serial killer would say...

Shit you caught me

Hold on I gotta clean the wood chipper

[–] MeThisGuy@feddit.nl 1 points 6 days ago (1 children)

Oh hidy-ho officer, we've had a doozy of a day. There we were minding our own business, just doing chores around the house, when kids started killing themselves all over my property.

[–] easily3667@lemmus.org 1 points 5 days ago

Really very frustrating, I was just trying to clean and they kept throwing their blood and random body parts everywhere. It was impossible to keep up.

[–] TheTurner@lemm.ee 5 points 6 days ago

Yes, you are correct. It's because of the slow acceptance of new technologies by the NHSTA.

[–] Frederic@beehaw.org 11 points 6 days ago

In Canada we have mandatory DRL (Daytime Running Lights) and often, cars use high beam with a low voltage or PWM. When people replace their standard bulbs with LED bulb, it means during the day you are flashed by high beam in your eyes, even in full summer at noon you can be completely blinded by cars coming towards you, it's fucking annoying!

[–] Rob1992@lemmy.world 3 points 5 days ago (1 children)

Its not the headlights, it's fuckera messing with their car or bribing the inspector to not fail them on broken auto adjust systems, or (for a while) people putting shitty aliexpres lights in halogen projectors

[–] Hansae@lemmy.dbzer0.com 4 points 5 days ago

It is the headlights, the UK has the MOT which is very harsh in testing and you cant just bribe your way through it (massive legal penalties for the garage performing the check). And if these lights are that bad while maladjusted then they're still a issue, malajusted bulb headlights are just slightly annoying not totally blinding.

[–] monotremata@lemmy.ca 3 points 6 days ago

HID headlights were just as bad, and those go back to the 90's.

[–] Evil_Shrubbery@lemm.ee -3 points 6 days ago* (last edited 6 days ago) (2 children)

What deregulation-used brain that that doesn't demand safe legal infrastructure for their roads made this meme?
(LEDs are the way safer tech, if they aren't used wrong)

Brighter headlights than incandescent bulbs provided is a safety feature - legislation needs to make you safe by insuring irl that it's not directed to other drivers (various countries also set max candles at various distances too, but that's not even the issue).

A yearly mandatory roadworthiness test & legislation about what the max distance from road headlights can even be positioned solves all problems (apart from deliberate long-beaming peoples peepers - which should be solved by fees/cops).

Not to mention nowdays few cars don't have auto-leveling or adaptive headlights. So it feels like a half-solved perform.
And again, like automatic emergency braking, govs could just demand auto-headlight-leveling as minimal equipment from some production date onwards.

[–] SparroHawc@lemm.ee 8 points 6 days ago* (last edited 6 days ago) (1 children)

The problem is that incandescent lights are 1) warmer in tone, which is less harsh for the same candle ratings, 2) have a more gradual boundary than LED projector-style headlights, which means you aren't suddenly blinded when the car coming towards you goes over a minor bump, and 3) aren't a point light-source with the reflector design they have unlike LEDs, and thus are less painful. NONE of these issues are dealt with in a vast majority of new cars (adaptive-angle headlamps would do a lot to help, but would only fix one of the three issues - and only when the camera can actually figure out when they should be lowering the angle, which is far from foolproof).

If I could easily replace the LED headlamp in my new car with an incandescent lamp, I would - because I could still see decently with my old car's headlights, and I wasn't at risk of blinding everyone in the oncoming lane next to me.

[–] Evil_Shrubbery@lemm.ee 2 points 6 days ago (1 children)

Oh, thx for the description, I'm starting to understand now.

There isn't any inherent reason why we couldn't use reflector tech with LEDs - there wouldn't even be anything wrong of you would exchange an incandescent bulb with LED if it was certified correctly (by the manufacturer, which actually exist), by which I mean with the right power & with full round and equal light emissions (for the reflector to pick up correctly). The LED emissions needn't be harsher (tho the cheaper ones def are, low cri led are more power efficient too, but project a diminished spectrum) tho I def understand you.

The projector style headlamps also come (came?) with incandescent (instead of xenon or led) bulbs which still had the issue you point out at your 2). It's not a bulb thing, it's a light casting thing.
And projectors (incandescent, xenon, or led) are indeed used exactly bcs of what bothers you - they bleed less light around their target angles so they are legally allowed to be brighter (since at level they can emit more light without it crossing the threshold of for much of it bleeds higher than allowed). Yes, this doesn't account for actual daily life, just a sterile average (which positively def affects safety too - ofc besides the issue is blinded drives you pointed out). But road infrastructure is a giant factor here. Cars shouldn't jump up and down due to road quality.

To points 2) & 3) I would add that it makes an enormous difference if you suffer from the slightest astigmatism - for me that was what caused the diminished vision when someone slightly blinded me (the pain is considerably less to in road situations).

It's what makes "single bright points" tolerable for short durations & it makes easier for the brains to compute around it (with astigmatism points become more like lines & brains now have to interpret/check those + lines are bigger than precise dots & it takes more info to process them). This isn't noticeable during the day & it doesn't necessarily mean your vision is below average.

[–] SparroHawc@lemm.ee 2 points 5 days ago

Cars shouldn’t jump up and down due to road quality.

I live in a hilly area. Any time someone with projector headlights is on even a slight downward curve that I'm facing, it's the equivalent of brights in my eyes. Even with adaptive headlights, cresting a ridge would still blast anyone on the other side for the short amount of time it takes for your car to realize there's someone there.

For point 3... You're right, and you're wrong. Light from point sources instead of diffuse sources is worse for your retina. The light gets focused by your eye's lenses onto a much smaller area, which can potentially damage the sensitive photoreceptor cells. Ideally, there would be regulations that limit a headlight's candles per mm^2 rather than just overall candles. Astigmatism makes it so the light glares across half your vision, which makes it worse for seeing other things on the road besides the headlight glare, but conversely makes it better for not murdering your retina because the light is spread across a wider area.

[–] synestia@lemmy.ml 6 points 6 days ago (1 children)

And yet I get blinded every single day

[–] Evil_Shrubbery@lemm.ee 2 points 6 days ago (1 children)

Seems country dependent. Maybe even mean purchasing-power related.

But it's a people problem, they either use illegal (for their vehicle) bulbs or the infrastructure doesn't demand better.

[–] Hansae@lemmy.dbzer0.com 5 points 6 days ago (1 children)

I live somewhere with mandatory intensive yearly inspections, still a issue and is even a issue on new cars (can tell via the numberplates here) which have just rolled off the lot. Fuck these shitty headlights.

[–] Evil_Shrubbery@lemm.ee 3 points 6 days ago (1 children)

Wait, the new cars are not law compliant?

[–] Hansae@lemmy.dbzer0.com 3 points 6 days ago (1 children)

They nominally are, I still get blinded by them. These are 25 plate fords, VW group, landrovers etc.

[–] Evil_Shrubbery@lemm.ee 3 points 6 days ago* (last edited 6 days ago) (1 children)

Can I ask in what situations?

Like on even, level road when they are facing you?
Or like a hilly road?

And we arent talking high beams or fog lamps (some people just drive with them constantly)?

Or are the cars loaded at the back which makes their headlights point to high up?
And people don't use this thing:
(This is what I mean by auto-leveling & that the govs should mandate it - people aren't doing it manually & don't know what this switch does ... or don't notice their headlamps are illuminating peoples faces in other cars.)

[–] Hansae@lemmy.dbzer0.com 3 points 6 days ago* (last edited 6 days ago) (1 children)

On a straight fairly flat A road, no clue if they've adjusted them properly or not thats besides the point, they're extremely blinding very consistently. The car I drive is very small and quite low to the ground. And these are absolutely not high beams, I've flashed a few coming the opposite direction because I thought they had high beams on, I am then blinded even further when they return the favour.

[–] Evil_Shrubbery@lemm.ee 2 points 6 days ago* (last edited 6 days ago) (1 children)

And also it's not this-ish (the angle depending on each person)?

[–] Hansae@lemmy.dbzer0.com 2 points 5 days ago (1 children)

Uh no its like a flashbang wherein my eyes literally have black spots after.

[–] Evil_Shrubbery@lemm.ee 2 points 5 days ago* (last edited 5 days ago) (1 children)

Wow, that sounds ... undrivable.
Especially if you say it's a regular occurrence.

Like, you wouldn't/are unable to see any pedestrians or cars in front of you. That is really not ok.

Stay safe somehow.

[–] Hansae@lemmy.dbzer0.com 3 points 5 days ago (1 children)

Ive had to pull over a few times, luckily the EU seems to be looking into it.

[–] Evil_Shrubbery@lemm.ee 2 points 5 days ago* (last edited 5 days ago)

That's good, I don't think we have much common legislation (delegated acts) for headlights.
(Oh, there is something, but it's way too short)

And I'm really proud of EU legislation, it has procedures that get shit done and in a predictable manner.

[–] Semi_Hemi_Demigod@lemmy.world 72 points 1 week ago (12 children)

If you focus the light correctly they’re not bad.

The problem is folks put new LED bulbs in old fixtures designed for non-led bulbs. These scatter light everywhere and annoy people. Plus they have to be even brighter because the light isn’t focused where it needs to go.

[–] DacoTaco@lemmy.world 10 points 6 days ago

Also just cars being too high/big. My car gives no issues to others, but fuck me those bigger cars...

[–] potoo22@programming.dev 39 points 1 week ago

Also, the newer massive trucks that are so high they blind anyone lower than them regardless of how properly it's configured.

i'm still amazed how these fucking lights got through regulation in germany. 'everything' is regulated here. but these blinding pieces of shit got through. i know the answer: money. as in cars, the crown jewel of the german economy. i hate them sooooooo much.
