The benefit of adaptive light is that the curve and the edge of the road
are better illuminated ~ fig. 69. Dynamic adaptive light is controlled
automat ically, depending on vehicle speed and steering wheel angle.
When driving around bends, the headlights are controlled according
to steering wheel angle . So that there is no black hole ahead of the
