Abstract: A motor vehicle headlight comprising a light source, a reflector, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on the reflector in a plane which is essentially vertical and parallel to the optical axis defined by the reflector, the spirit level being in a predetermined angular relationship with the optical axis. The spirit level is mounted on a hollow support having an end edge suitable for bearing against the rear face of the reflector around a lamp mounted in the reflector.

Abstract: A motor vehicle headlight comprising a light source, a reflector, a housing, and a front glass, and also comprising an indicator device for indicating the elevation direction of the reflector, the indicator device being of the type comprising a spirit level mounted on the reflector in a plane which is essentially vertical and parallel to the optical axis defined by the reflector, and the spirit level occupying a predetermined angular relationship with the optical axis. The spirit level is mounted on a support suitable for being removably and temporarily installed in a lamp hole provided in the reflector, with the support then replacing the lamp.

Abstract: A motor vehicle headlight of the type suitable for emitting at least one beam that is delimited by a top cut-off and that includes an approximately central concentration spot, the headlight comprising: a filament lamp (100); a reflector (200); and a closure glass (300); the headlight including the improvements whereby said reflector comprises: at least two lateral zones (202, 202') that form small images of the filament defining said concentration spot and forming said cut-off; and a central zone (201, 201, 203, 203') which reflects the light rays emitted by the filament to cause them to converge in a region at a substantial distance from the closure glass while simultaneously forming large filament images which are spread out below said cut-off; with said lateral zones and said central zone joining one another with second order continuity in two essentially vertical planes that are parallel to a central optical axis of the headlight and are disposed on either side thereof.

Abstract: A dipped headlight for a motor vehicle, capable of generating a dipped beam situated beneath a generally horizontal cutoff, the headlight being of the type comprising a lamp having an axial filament (100) emitting light freely in all directions thereabout, a reflector (200) having an axis (Ox) extending beneath the axis of the filament and parallel thereto, said reflector also including a surface without discontinuity, and said headlight further including a closure glass placed in front of the reflector and suitable for spreading said beam in a horizontal direction, said headlight including the improvement whereby the reflector includes two diametrically opposite first quadrants (201, 202) whose surfaces are at least approximately two portions of paraboloids having focuses situated in the vicinity of respective axial ends of the filament in order to generate filament images which provide light concentration situated beneath the cutoff and offset sideways relative to the headlight axis, with the other two quad
