Abstract
A motor vehicle lighting system comprises a lighting switch having a daylight signaling position and two night driving illumination positions, with a running light (or headlight) having a discharge lamp cooperating with a reflector to produce a night driving beam essentially without any cut-off. The running light has a discharge lamp cooperating with a reflector to produce a night driving beam which essentially has no cut-off. The system includes a means such as an absorbent element which, when the lighting switch is put in its daylight signaling position, diverts a fraction of the light intensity of the emitted beam so as to produce a beam of reduced intensity as compared with the same lamp powered under the same conditions.
