A headlamp assembly for illuminating surroundings of a vehicle, including at least one headlamp, a temperature sensor, and a control device. The at least one headlamp comprising a multiplicity of light sources, the multiplicity of light sources (being divided into a first group and at least one second group. The temperature sensor being configured to detect a temperature in the at least one headlamp. The light sources of the multiplicity of light sources being thermally coupled. The control device being configured to ascertain a current temperature ascertained by the temperature sensor in the at least one headlamp and, in the case that the current temperature in the at least one headlamp exceeds a predefined temperature threshold value, to select the first group or the at least one second group for a power reduction, depending on an operating situation of the vehicle and to reduce the power of the selected group.
