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

The method involves reading a position signal which represents a position of an object (140) in front of or next to a vehicle (100). The light emission from the headlamp is changed on the object or in an environment (130) of the object using the position signal. The changing of a varying lighting pattern (190) on the object or in an environment of the object is broadcasted to change the light emission of the headlamp of the vehicle. Independent claims are included for the following: (1) a device for changing light emission of a headlamp of a vehicle; and (2) a computer program product with a program code.
