It is starting to dawn on me that the lack of answer had to do with "what is he talking about". lol Sorry.
Headlamp - Wikipedia
The top picture is asymmetrical low beams. All high beams are symmetrical. The advantage is that the light on the right side of the road lights up further forward to see pedestrians, or whatever else is on the edge of the road, animals not looking at you, or an obstacle. On the left side of the road the low beams have a much shorter beam not to blind oncoming traffic.
A lot of people are afraid that such headlights will blind oncoming traffic, but headlamp lenses are shaped so they have far less stray light upward than the ones you are used to here, even if the bulbs have more watts. Gives better light, and safer driving.
