Is it time to ban LED Headlights

Watched that the other day. Looks amazing!

Currently looking at Q7s with matrix LED and with Laserlight. They look immense but can’t help but think they’re complete overkill. those digital ones are something else though.

Yea if you have perfectly smooth and clean tarmac like in the video lol. It's so clean it's almost as if it's CGI or they had it scrubbed first...

Doesn’t look like CGI to me..

Projecting a guide to braking distance to the vehicle in front could be interesting :cry:

(I expect they'd get a lot taken back because the system was "faulty" though).

My matrix lights work amazingly.
Puts a dark box around any cars in front and moves with them.

Yeah same on my VW. Amazing tech. having full beam for the road and several black boxes surrounding vehicles around me is great.

It will be about 2 feet, in line with the Audi driver following distance.

It doesn't work over long enough range though. People still get dazzled on straight bits of road until they are close enough to get detected. Especially on motorways they will be annoying drivers in the distance.

Mine worked last night with a car coming over brow of wide country lanes easy a mile away, and it killed the segment to dark. This is where the pixel type are better as they have the segments with vertical resolution aswell. Could have blocked light to the high up car but left some light going to the road/verge.

So basically your point isn’t true.

can’t wait to try the new Range Rover version.

Bjorn has a few good videos of adaptive LEDs across a range of cars.

The EQC one looked like it worked great, as did the ID3/4 and Polestar.

And then have the Range Rover version replaced multiple times under warranty haha

I wouldn’t have it long enough Darling.

Good example there of how it is supposed to mask out a car ahead:

But that is not my experience when being followed by cars with this tech when in vans and pickups where despite the lights being dim in the rear view mirror or looking behind they are like small suns in the wing mirrors.

Hope it’s the Nasher segment that goes dark, problem is it would be so small no one would actually notice

It’s just highlighting your “car” isn’t really appropriate for the road. Stick to dragging wood around in the day.

I find some of the matrix systems struggle with motorcycles. With increasing frequency I am being illuminated by oncoming cars with matrix LED lights. Some of them catch up after a bit but some don’t.

Not sure the need to post that but whatever.

Watching a couple of the videos linked above it seems quick adapting to a pair of lights but struggles with single lights, reacting a bit later to street lights, etc. but quickly masking our a pair of lights above a garage.

Yep, exactly. They won't react to all the lights they see or it would be blocking out everything. So they sometimes other vehicles too. With automated systems there are always grey areas.

???? Mine works at massively long distances, further than I would have swapped to dipped if I was in control of the lights.

Indeed. Not just head on but when behind as well, my mirrors turn into laser beams… lol.

renewed my HGV licence recently...don't know if it's reactive (high beam assist?)/matrix lights or just people not switching them soon enough but noticed it quite a bit driving at night, the cab has high and low level light bars too so no shortage of light to detect! are the matrix lights so good they manage to switch off the sections that detect the light but still shine the full beam straight in to my retinas?

never driven a car with matrix lights but it must be hard to be sure that they're not causing problems for other drivers?

reactive/manual have no excuse!

In my car each section cuts off from the detected car upwards. So in essence it's not placing light above a section which is cut off.

Unsure about other implementations.
