Headlight's too bright

The problem is exacerbated due to the prevalence of SUVs which have a higher headlight position than a typical hatch, or saloon.

How often do you clean the inside of your windscreen? I've recently had to do a few runs on dark roads and the 1st few times it was OK, last time it was bad as the inside of my windscreen was dirty and I had a lot of issues with dazzle. Are you using AC or the fans to keep the windows clear?

When was your last eye test and have you been tested for astigmatism? Astigmatism causes you to see dazzle

Car lights are getting brighter but people have been complaining about fog lights being terrible for years yet I've never had an issue with fog lights or the current lights on cars.

What is an issue is the amount of people who don't turn off high beams, usually on dual carriageways/motorways, but that's not an issue with the vehicle.

UK drivers say the same

There was nothing wrong with halogen bulbs. Better for human vision too because they have yellow tint. But no, LED are fancy and look shiny in a show room. Perceived distance vision is longer with halogens too because there is no sharp edge where brightly lit area stops and darkness starts, as is the case with LEDs. With LEDs you see very bright area and then it’s pitch black and your eye cannot adapt to recognise any object in darkness.

Think the US never allowed LEDs on the roads?

I used to enjoy driving country side here with so many cars still on halogens because they are older but they are disappearing now with people changing to newer cars.

I agree with the above poster, it's not just the increase in light intensity in lumens that's the issue it's a combination of that, the colour temperature and the sharp beam cutoff.

I'd say the same for street lighting too. In my mind the old orange sodium lighting was much better.

In my opinion it's the sharp cutoff of the beam pattern that's the main issue, and that was and is an issue with conventional halogens and HIDs that use projector setups instead of the older reflector setups.

With the older reflector headlights the edge of the beam not only faded away gradually for the part of the beam that illuminated the road, but also the upper part that would be visible to an oncoming driver. If the road surface is uneven or the oncoming car is coming up a slope towards you, with conventional lights you'd get some light shining into your eyes, but it would be much less than the full power of the headlight. But with high power LEDs you get the full force if the beam in your eyes.

Complain to MEPs - it is not a problem that can be solved in Ireland, it needs EU wide regs realistically.

Arguably the max height needs to be changed. The existing height specs seem to have allowed for diminishing throw of halogens that's gone out the window. So the directional of the LED should be lowered.

Would require non led and led testing in the likes of NCT centres to be different.

I can just about put up with the glare BUT what really p!sses me off is SUV's and vans that light the whole of a normal cars interior up like a solar flare when they come up behind you at night.

Yes, I remember when I first had a car with LED headlights, I was driving along behind someone I knew, and they actually stopped and got out to ask me what was up, as they assumed I was flashing them! This was on a relatively smooth R road in Wicklow, not some pot holed boreen.

I was blinded by a Tesla jeep driving behind me recently driving round the Ring of Kerry (Killorglin to Cahirciveen). It was pitch dark but the road is too twisty to overtake, so he sat on my bumper for 40 mins. I could barely see as his lights were hitting all my mirrors at just the wrong height! It really was awful. He was so close and the roads are so narrow I couldn't even find somewhere to pull in and let him past.

You could adjust the dial downwards slightly brings the beam closer towards your car.

I find Tesla's in particular are very bad. I think that their strategy is to aim the lights as high as possible so as to help out their camera systems, as they have no radar.

As for having 20:20 vision and still being blinded, your eyes can be perfectly in focus, but still suffer from glare at night, it's not necessarily the same issue. Also, do the following.

1. Make sure the inside of your windscreen is clean
2. Use A/C to prevent even light fogging in winter
3. Make sure your wipers are good and use good screenwash

All unreasonable things to expect from every vehicle at all times on the road.

Reasonable would be EU legislation to Combat the source of the issue. Poor design manufacture and implementation of lights.

and tractors, full beam specialists that shower

I thought this was just me getting older and crankier. Teslas are by far the worst offenders, absolutely blinding at most angles.

..

LEDs themselves are not the problem, it's the system they're use with. They can be pretty poor alright when static, but when they're used by those automatic/self levelling systems with adjust the beam depending on the ambient lighting and road traffic they work great.

Auto dips are fantastic for the person driving, but they arent great for other drivers. Especially if you're going around corners the tech just isn't up to it - it just doesn't dip.

You'd think so yet they are still blinding oncoming drivers which would solely indicate default settings are above what should be acceptable. In this scenarios it's worse as they don't have the excuse of halogen in their lineup at all. Just really poor design and testing.

The lighting system will be designed and provided to Tesla by a major Tier 1 supplier, using components almost certainly used in other vehicles.

Failing EU standards due to design would be a catastrophic warranty issue for the supplier, so they won't sell something that isn't compliant. (By this I mean NCT)

I firmly believe it's a choice by Tesla to aim their lights high to aid their Vision Only ADAS.

The other side of it is, it could just be poor suspension components which causes the lights to aim high (a little slop on a ride height sensor will cause a big angular error), and Tesla have also had documentated issues where they Zero'd the ride height sensors during a software update, which if done on a hill would cause an error.

I've recently moved to the US, and my 2021 car buad matrix lights which do a little show when I turn on the car, but are actually disabled when driving. I must see if I can get a dealer upgrade, as the car is under warranty and I'd be hesitant to mess with it myself.

It's not the M11 is one of the newest roads in the country. Absolutely blinded from behind in rear view and over the central divider by these LEDs, the problem is most definitely not our roads. The complaints about this are pretty ubiquitous regardless of country.
