funny how toyota was the first to push the agenda back in 2013 for these new headlights.

all EURO Toyotas have much better headlights than US models.
EU has always led in rules for headlights that excel at

(a) actually lighting up the road more than US spec (b) reducing glare while doing it

US has laws and rules for photometrics, but they are not as extensive as in EU

good that better OEM assemblies are coming

As mentioned in the article, this type of headlight has been legal in the US for going on half a decade. But finally the first vehicle whose manufacturer was willing to put theirs through the onerous process of getting approved is coming out 5 years later.

Given this, even if being cautiously optimistic, it seems like it will be a long time more before we really see this technology go mainstream here as it did in Europe. But fingers crossed.

Yep, often this was a hidden feature you could enable on your BMW, Mercedes, VW with a coding tool.

I converted my GTI and 340i to ECE pattern headlight beams, and enabled the anti-dazzle high beams.

Driving along at 62mph+ / 100km/h with the auto-high beam set to ON, you could see your high beams focus and divert around the cars in front of you or oncoming in the other lane.

Additionally, driving at low speeds with the wipers on turned on 'fog mode' where the beams would lower and go out to the sides. This better illuminated the edges of the road, and improved safety.

It is genuinely amazing how archaic the laws in the US are regarding headlamps and tail lamps.

yeah it 'would' be legal years ago, but it has to pass photometrics for every specific make/model/trim/ride height, to be certified and sellable...which takes a ton of testing with expensive equipment.

none of it is by guess 'oh it looks good to me'

it's very precision optics and measuring gear.

Wait. I already had this tech on my 2026 Maybach S680.

No — the US-market Maybach S680 didn't have functional adaptive driving beam, even though the hardware was capable of it.

The exact hardware depends on how the car was optioned. A US Maybach S680 could come with Multibeam LED headlights or the higher-end Digital Light system. With Digital Light you get the road-projection symbols in the US, but still not the driving adaptive beam.

There's an aftermarket workaround. Independent coders can activate "intelligent high beam plus" on North American cars fitted with multibeam headlights (option code 640), which lets the car dim individual LEDs around cars in front while leaving the high beam on elsewhere — effectively unlocking ADB-like behavior that Mercedes left off from the factory. That's a third-party modification, not a factory feature, so it carries the usual caveats around warranty and legality.

Well than that is exactly my Maybach was option with. Adaptive headlight. The Maybach was build completed in Stuttgard, Germany and ship over. This is a S680 V12 model

Yeah, _where_ it’s manufactured doesn’t matter. The OEMs disable the functionality that isn’t legal/certified for US roads on units that sell in the US.

I know how now. My car was build and sold to me as European buyer (Portugal to be exact). Than it shipped over via Portugal as personal vehicle. Custom did not even go thru detail about the specifics specs of the car when I picked up at the Port of Long Beach.

Check to see if it has the amber reflectors in the headlights. If it doesn't have them, you can confirm that it's a European model and SHOULD have the full adaptive glare-free headlight capability enabled.

On a side note, I hope this tech is retrofitable in our cars. I've coded the glare-free high beams on many US-spec BMWs (either with BMW Adaptive LED lights or BMW Laserlight). It's genuinely life changing how good these adaptive headlights are.

Confirmed. It doesn’t have amber reflector.
