Always high "projector" headlights have been common for a decade[1]. They use a flap to block the top half of the beam, creating a strong line below which the headlights are always full power. When a car with these headlights goes over a bump or is on a strong incline, other drivers are exposed to the full high beams. The height of the line is also adjustable, and it is often adjusted to always be too high.
