Hold your horses, don't pop any champagne corks yet.
First of all, "adaptive headlights" have been legal here for years. What's under discussion right now (legal in Europe/rest of world for ten years, legal in Canada since 2019, still not legal in the USA) is
adaptive driving beam headlamps, which aren't the same as "adaptive headlights".
Second, no, ADB has not been "approved for the US". That's not an accurate headline or accurate understanding of what has happened. The infrastructure bill (now law) requires NHTSA to amend FMVSS 108 within two years to allow ADB as per SAE J3069. That's nice if it ever actually happens (let alone within the two years), but if you'll look at
this and
this and
this, you'll see the odds and track-record are against it.
