Unlocking the full functions of the multi-beam LED headlights
So let's recognize good behavior and hope for the best.

It's a fabricated "issue" by a sponsor here with no morals to be used as fuel for fearmongering in a slimy attempt at self-promotion.
"Use me or you won't get the "real" thing and look at all the problems you will have! Only I can save you. Good luck... good luck."
Nothing but fear-based self-promotion.
Pfft.




I think the North American headlights don't have the hardware to support the blue light AFAIK.
The Best of Mercedes & AMG




If so, how exactly was it phrased to the service writer, or did they already know what to do?




My guess .. wait another 3 yrs before they will actually have it enabled right from the factory … but do note the US/Canadian version will still do not have 100% functionality when compared to the European version.

Re-certify!?!?!? Really!?!?! UFB!!!!
From what I've experienced, my lights function nearly identical to the embedded video from a previous post here.








I wonder for those folks in larger cities does the W213 ILS+ activate more frequently? As much as I hate having an un-activated feature as awesome as ILS+, I would only want it if I can actually notice the difference. Thanks in advance!
EDIT: Found another thread with very specific experience here. In well-lit city driving, apparently not a large difference vs. darker roads which makes sense.

For ILS, the other following functions are described:
- Active headlamps (already there on US stock cars)
- Cornering lights (already there on US stock cars)
- Traffic circle and intersection function: supposed to turn on both cornering lights at a traffic circle or intersection
- Highway mode function: Supposed to increase the range and brightness of the cone of light on highways
- Enhanced fog light function: Supposed to increase edge illumination when the rear fog light is turned on
- Bad weather light: reduces dazzling reflections in rainy conditions by selectively dimming individual LEDs
- City lighting function: Uses broad distribution of light to improve lighting in lit up urban areas and at low speeds
The active curve lights are also supposedly able to start curving the lights in advance of a curve depending on what equipment the car has, I have Driver's Assistance Package so I would assume the camera system would be able to see that. Has anyone noticed this?
Might just need to drive it for a longer time to notice those if they did get activated but wanted to check with folks here first.
Also wanted to chime in with another positive experience and recommendation for RJAutomotive: the dongle got here fast, and the coding was on time, convenient, and efficient. Professional and responsive to questions as well.

You can very clearly see the light curtain notching out the car in front while the rest of the roadway is nicely lit up.
I do see the lights brighten up when I activate the turn signal to the right. It might do it to the left too, but can't say I recall.
"Adaptive Highbeam Assist Plus" is the functionality where you can leave your high beams on all the time and the light curtain notches out cars and overly glaring signs in front of you while keeping the rest of the road lit up. This is what we enabled through remote coding in the US and it works beautifully, I notice it working pretty frequently.
"Intelligent Light System" is the suite of light features that I mentioned above, where the shape of the cone of light and brightness and such adapt to wherever you're driving, motorway, city, bad weather, etc. After the coding we have the toggle for it in the Settings -> Light menu. In the US, with the Lighting Package, by default we already get active curve illumination as well as the cornering lamps that turn on when you indicate at low speeds or turn the wheel either direction. It's the other modes that I'm wondering if we also got enabled when we did our remote codings or if that requires further coding.
I was able to confirm this via testing. I turned off ILS in the settings and kept the highbeams on and the notching out was still working, so AHA+ and ILS are separate functions. I then kept the highbeams turned off and went on a drive tonight and toggled the ILS setting on and off at various times and didn't see a difference in the light cone in the city and on the highways. I also didn't see the cornering lights both turning on through intersections and traffic circles and I didn't see any difference in light with the rear fog light turned on. And lastly, I didn't see the headlights "pre-curving" as I approached curves in the road. So I'm wondering what's going on there. RJA did say that all the features get enabled, so not sure if I'm not noticing or looking in the right places, if it needs further coding, it just doesn't work on US roads, etc. The two features working in conjunction would be headlight heaven.
