Overall rating
Distance at which headlights provide at least 5 lux illumination:

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

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
