Abstract
A motor vehicle headlight reflector and a headlight constructed therefrom, wherein the reflector comprises a plurality of laterally juxtaposed zones bounding transition lines with a break of slope. Each zone has a smooth reflective surface and is adapted to spread light horizontally between two limits obtained in the immediate vicinity of the transition lines. The limits of horizontal spread in each zone varies progressively with displacement along the transition line concerned. The invention also includes a method of making the motor vehicle headlight reflector.
