Method and advice for adjusting the light output of at least one headlamp of a vehicle

The method involves recognizing an unstable vehicle driving state representing a direction which is different from a specific driving direction of a vehicle (100). A drive signal (135) for changing the light emission of a headlight (130a) of the vehicle is provided based on the detected unstable driving state of the vehicle. The light radiation characteristic of the headlight of the vehicle is adjusted according to the drive signal. The driving state of the vehicle is detected using image data of a camera (160). Independent claims are included for the following: (1) a device for adjusting light emission of headlight of vehicle; and (2) a computer program product for adjusting light emission of headlight of vehicle.
