Which cars have these?
Is it time to ban LED Headlights

Which cars have these?
Acura apparently are 11,000 lumens and even their DRL are 1000 lumens.
But my general point was perhaps there should be a maximum of say 3,000 lumens? Rather than leaving it open ended?

I should have clarified, which UK market cars have these? I don't think many if any UK cars have lights like this so not sure what value a 3000 limit would have. Presumably we've already reached the peak back when Xenon headlights were around because most cars since then no longer have headlight washers, indicating they are under 2000.

Actually that was a mistype. Was supposed to be around 25% for the RAC.
I haven't looked for the Gov figures - How does the 25% compare?
It's not so much the lumen output as where those lumens are directed. If all of them are focussed into your eye, you ain't seeing shot through that!
It looks to be about 0.3% of collisions in 2022.
The most common cause at 34% being failure to look properly.
I'm surprised it's as high as that
That was clearly nonsense, I expect barely 25% of accidents even happen in the dark given traffic patterns, nevermind be directly attributable to oncoming lightsWhat did you think of the idea that it was 25%
I'm not sure where you are getting this number from. You can find a recent RAC report here which I have to presume is the one referred to, it says this:
Road traffic accidents data up to 2021 does not show an increase in accidents caused by headlights
38. In the Department for Transport’s road collisions, vehicles and casualties statistical dataset, one of the contributing factors to accidents that is monitored is ‘dazzling headlights’. The latest collated statistics refer to 2021 and include 10 years of data (Exhibit 1). This does not appear to show any increase in accidents caused by collisions, although it must be borne in mind that the last two years were severely affected by Covid restrictions (March- June 2020, September– November 2020.January– July 2021).
39. In the USA, the number of traffic accidents caused by glare from the high-beam headlights of oncoming traffic at night accounts for 12 per cent to 15 per cent of all traffic accidents. (25)

That reference, (25) is to this paper from 1993 which, as far as I can tell, contains no such figure. Or indeed any figure on the number of traffic accidents caused by glare from high-beam headlights. Instead it is a paper on the development of a model for assessing visibility. Even if the figure were correct (which seems highly doubtful) it is a figure regarding people dazzled by high beams rather than people dazzled by overbright dipped headlights.

ROSPA reckons it's closer to 40% in the dark...That was clearly nonsense, I expect barely 25% of accidents even happen in the dark given traffic patterns, nevermind be directly attributable to oncoming lights
Trying to recall exact figures (it was definitely 20-something) from an RAC report, which I thought had already been posted. Might have been in another thread.
Did they ask the dead people whether they were dazzled?
Yea one article said it's likely to be higher numbers in reality. A lot of accidents just seem to be put down to speed by default.

Speed is always a factor when you think about it.

I think the rules should be updated to allow LED/xenon upgrades in cars that didn't originally have them, provided it can still pass an MOT beam pattern test.
Correct. I mean take an accident where two vehicles collide head on at 70mph. If both of them were doing 5mph then there would have been no injuries...............

You can to any car that is older than 1st April 1986.
Hence I am just abut to fit LED headlights to my 1967 MGB.

Guess an E marked H1/ H4 / H7 bulb would start to allow this. Could be a start, Night breakers etc are what ive been using the in the Insight for years.
But then i thought LED and Xenon were no better than Halogen?...

But why allow it for old cars and not modern ones? Doesn't make sense.You can to any car that is older than 1st April 1986.
I thought it was a no no to fit LED bulbs into reflector housings?You can to any car that is older than 1st April 1986.
Only in projector type housings were they any good.
