Matrix headlights on motorways

[El-Cap]

With the darker nights I am getting used to the matrix headlights which seem to have three settings main beam, auto, and dipped. The main beam(blue light) seems to self dip, the auto (head lamp with A symbol) is automatic and finally dipped (no symbol)
- as far as I can work it out!

I am finding the auto lights fine on A and B roads. However on motorways when I tried them there were a couple of people flashing in the other carriageway (this was in low traffic volumes so it was surely for my benefit!)

Anyone got any advice for motorway use of these lights?

So are you keeping the high beam assist on?
I personally keep lights on auto but high beam assist on only when I'm on dark country lanes etc

Essentially where I would be usually pulling on the high beam stalk, those areas I keep the high beam assist on to avoid having to pull the stalk and then I switch it off once it is more lit
stops the lights going into beam mode on motorways etc

unless I've read your thread wrong...

I don't think you have read it wrong - particularly when I don't really know what I am talking about!!

I think would have had high beam assist on on as I hadn't appreciated there is a difference between the two. So I take it that if I have the auto on (the one with an A symbol) that will work OK on dual carriage roads then?

I have a similar problem with my leds, they don't dip on the motorways or dip early enough and I keep getting flashed

They don't dip brilliantly, where there is an obstruction between you and oncoming traffic, such as motorway barriers, armco, or even a load of taller weeds.

The technology isn't good enough for those situations sadly.
Just the way it is..

Yep, I reckon it's the High Beam Assist bit which is rubbish, as it is on most cars with any sort of headlight. I leave it off on Motorways.

However, the "matrix" function works almost impeccably on A and B roads.

I didn't think there was a High Beam Assist on Matrix lights?

You push the stalk away once, and A appears...
In town and lit areas (known by gps location) it dips.
Leave town and full beam comes on.
The matrix system will then dim areas when required, either behind cars, or oncoming.
How do you make High Beam Assist kick in? (I read this as it swapping between full and dipped when other cars are detected, but not partial dimming ala-matrix)

I think the problem is the detection distance... Even on long straight A roads I sometimes get flashed and then the lights dim.
A slight annoyance to oncoming cars, but maybe they are too eager to tell you that you are still on full beam.
The whole system tends to see other objects well, even if a second or two too late.

Definitely high beam assist on matrix lights. Push once get the high beam symbol and the a in bulb as high beam assist. Push forward again, get blue high beam, no high beam assist and see how often you get flashed. Got to remember can track 9 cars, or light objects. If lit motorway/ dual carriageway, cars in front of you, street lighting, reflective signs, oncoming cars, central reservations etc it doesn't stand a chance, as will overload the inputs.

I think the problem maybe predictive flashing by some oncoming drivers who are not actually dazzled themselves but believe you have lights on full beam because they can see the indirect light spread. I don't know where max 9 light objects comes from as each LED within the matrix lamp has its own sensor and will react accordingly.

I read somewhere that Wipac developed the system originally for racing with each LED shining down a small tube that is also fitted with a sensor. They don't actually "track" at all but rather sense a light source in each LED (or group of LEDs) direct path and then dims that LED/group. This is completely different from the non matrix lamps that use a camera as the sensor for "active" control


hope this helps

Not sure about this thread. Is it about Matrix lights or LED lights? The Matrix lights have an individually-adddressable array of about 25 or more LEDs in each lamp, which are controlled by the camera. The LED lights are - as far as I am aware, either on full beam or dipped; not sure if they are camera or light-sensor controlled. Which system is being discussed here?

BTW: I have done 23,000 miles (only some of it at night!) on Matrix lights and only been flashed once or twice. Although I am never flashed on motorways with them on high beam, I turn them off because they occasionally miss an oncoming car because of the crash barrier.
