An aircraft light comprises a housing, at least one light source to be cooled, the at least one light source being arranged in the housing, a heat sink element thermally coupled to the at least one light source and defining a cooling surface exposable to a cooling airstream for the cooling airstream to flow along the cooling surface in a flow direction. The cooling surface extends between upstream and downstream end portions spaced apart in the flow direction and means for generating a pressure difference between the upstream and downstream end portions of the cooling surface. Due to the pressure difference, a cooling airstream flowing along the cooling surface is created.
