Abstract: A motor vehicle headlamp has a device for generating a headlamp beam, together with a cover glass. A series of projecting elements is provided in the vicinity of the cover glass for location of a beam adjusting apparatus. At least one of these projecting elements is constituted by a portion of a movable member which is displaceable between a first or retracted position and a second position, in which this portion of the movable member occupies a predetermined locating position with respect to the cover glass.

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.

Abstract: A motor vehicle headlamp of the type comprising a lamp, a reflector in which the lamp is mounted, and a glass suitable for being received in an opening in the bodywork of the vehicle, the headlamp being wherein the glass is fixed to the bodywork in the region of said bodywork adjacent to the opening. This serves to eliminate defects in mutual positioning between the glass and the bodywork due to manufacturing tolerances.
