Abstract
A set of left and right motor vehicle headlamps, each headlamp including a reflector associated with a light source and a closure front-glass. In accordance with the invention, the left and right headlamps are respectively adapted to generate horizontally spread left and right illumination beams, each beam having a fuzzy edge on the left and on the right, said edges being asymmetric relative to the axis of the road, the left edge of the left beam being offset angularly to the left relative to the left edge of the right beam, and the right edge of the right beam being offset angularly to the right relative to the right edge of the left beam. Applications include forming homogeneous beams with a wide spread.
