Abstract
The present invention relates to an automobile headlight comprising a parabolic reflector, a front glass and a twin-filament lamp for far-beam and dipped-beam located on the optical axis of the reflector on either side of the focus thereof, said headlight being characterized in that a screen located in the front and in the upper part of the lamp defines on the reflector a zone which is struck only by the rays issuing from the far-beam filament. The corresponding zone of the front glass is also determined solely as a function of the far-beam filament.
