Abstract
A vehicle lighting device includes at least one headlight, a position and/or acceleration sensor, and a control unit for adjusting a light/dark boundary of the headlight. Pitch movements of the vehicle can be detected by the position and/or acceleration sensor, and a change in the light/dark boundary due to the respective pitch movement can be compensated for by the control unit. The position and/or acceleration sensor and the control unit are arranged in the headlight or directly on the headlight.
