Abstract: A method for regulating the light emission from a vehicle light, wherein a road user located in the light emission direction of the vehicle light is detected, and the light emission from the vehicle light is changed, whereupon response data on the response of the road user to the change in the light emission are acquired. Prediction data indicating the response expected from a road user located in the light emission direction of the vehicle light to the changed light emission are determined. The acquired response data are compared with the determined prediction data, if the prediction data deviate from the response data, the adjustment in the light emission from the vehicle light by which a reduction in the deviation is predicted is determined, and the light emission is regulated according to the determined adjustment. Further, the invention relates to a device for carrying out this method.
