Abstract
An automotive light is provided having a substantially tub-shaped rear casing designed to fit to the vehicle body and a front lenticular half-shell which closes the opening of the rear casing and has at least one portion of transparent or semi-transparent material. The front lenticular half-shell includes a rear portion substantially aligned with the rear of the vehicle body, and a lateral portion substantially aligned with the side of the vehicle body. The automotive light also includes a strip light source designed to emit light when powered electrically and a light guide plate of photoconductive material shaped to substantially match the profile of the strip light source and housed inside the rear casing in a position substantially perpendicular to the rear portion of the front lenticular half-shell. A first side of the plate conducts light from the strip light source into the body of the light guide plate, and a second side of the plate directs light propagating in the light guide plate onto the lenticular half-shell. A transverse light-extracting band is provided to locally extract light onto a lateral portion of the front lenticular half-shell.
