Low beams
On the straightaway, visibility was good on the left side of the road and fair on the right side. On curves, visibility was inadequate in all 4 tests.

The low beams created some glare.

High beams
On the straightaway, visibility was fair on the right side of the road and inadequate on the left side. On curves, visibility was inadequate in all 4 tests.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway, on both left curves and on both right curves.
