Abstract
A motor vehicle headlamp comprises a housing, having a cover glass defining, with the casing, an internal space of the headlamp in which the light source is mounted. The headlamp includes ventilating means for ventilating the internal space, this being associated with the housing. The ventilating means comprises two projecting portions of the housing, one projecting outwardly and one inwardly. Each projecting portion is closed at its free end by a cap. The outward projecting portion and its cap together define a first duct and a second duct, communicating with each other through a bend, while the inward projecting portion similarly defines a third duct and a fourth duct, again communicating with each other through a bend. The first and third ducts also communicate with each other, and the second and fourth ducts are open, respectively, downwardly to atmosphere and upwardly into the internal space of the headlamp.
