The light for a vehicle, particularly a flash warning light for an aircraft, is provided with at least one LED (10) bearing a semiconductor chip (14) emitting electromagnetic radiation. The semiconductor chip (14) emits blue or UV light.

The cooling surface (36) extends between upstream and downstream end portions (40,42) spaced apart in the flow direction and means for generating a pressure difference between the upstream and downstream end portions (40,42) of the cooling surface. Due to the pressure difference, a cooling airstream (52) flowing along the cooling surface (36) is created.
