Low beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good in all 4 tests.

The low beams created some glare.

High beams
On the straightaway, visibility was good on both sides of the road. On curves, visibility was good on the gradual right and gradual left curves and fair on the sharp right and sharp left curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the sharp left curve and on the sharp right curve.
