Abstract
A headlight device for a vehicle has at least two headlights, each emitting a screened light beam with an upper bright-dark limit, which on a counter traffic side and on a traffic side has different portions. A portion on the counter traffic side is arranged deeper in a vertical direction than a portion on the traffic side, and the portion on the traffic side extends so as to ascend starting from the portion on the counter traffic side over a part of the extension of the portion on the traffic side. The headlights are formed so that the light bundles are emitted with different bright-dark limits. At least one headlight emits a first light bundle with a bright-dark limit, with the portion which on the traffic side is located higher in a vertical direction than the portion of the bright-dark limit at the traffic side of a second light bundle emitted by at least one second headlight. A direction of the second light bundle is changeable so that a position of its bright-dark limit is changed at least in a vertical direction.
