Abstract

A motor vehicle lighting device has a housing and a cover plate covering a light exit hole in the housing, at least one ventilation intake opening and at least one air discharge opening, wherein an air guidance structure is disposed on the outside of the ventilation intake opening. The air guidance structure acts to deflect air that flows along the outside of the lighting device as a result of the effect of wind caused by driving, into an interior of the lighting device.
