That must have been what it had because when a vehicle approached the light cut down and went back up afterwards but no dazzling in my mirrors.I had a lift from someone in a top end BMW and it had what he called adaptive lights. They cut areas of the beam out around other vehicles. Amazing technology to watch in real time and nobody flashed us so I guess it was effective from the other direction as well
This explains itI hate to think how expensive it will be to maintain for future owners
