Abstract: An automotive light comprising a lighting assembly which is located inside the rear body, is adapted to backlight a corresponding transparent or semi-transparent sector of the front half-shell, and comprises: a pair of light-guide bars made of photoconductive material, which extend toward each other inside the rear body, while remaining both substantially grazing the front half-shell, and have their respective proximal ends adjacent and aligned to one another; and a pair of electrically-powered light sources that are located within the rear body each adjacent to the distal end of a respective light-guide bar, and are oriented so as to direct the light produced inside the body of the facing light-guide bar; the proximal ends of both light-guide bars being shaped so as to form respective plate-like heads that are locally substantially coplanar to each other and are arranged inside the rear body one spaced beside the other, so as to form/delimit therebetween a small transversal slot, which is substantially strai

Abstract: A system for determining the reflectance of a reflector of a lamp of a motor vehicle. The system comprises a light source designed to emit a predetermined light beam to illuminate the reflecting surface of the reflector, imaging capturing apparatus that is arranged so as to capture a series of images) containing the illuminated reflecting surface of the reflector, a processing device that is configured so as to digitally remove a first component (LS2) associated with a first photometric quantity of the light source from the images) so as to determine a second component (associated with the first actual photometric quantity of the reflector to determine the reflectance of the reflector based on second component.
