Abstract
A lighting device for a motor vehicle includes a light source for sending out a light beam. The lighting device also includes a lightguide of elongated shape made of a plastic, primarily transparent material for guiding the light beam, while a portion of a mantle of the lightguide forms an exit surface for emergence of rays of light of the light beam, wherein another portion of the mantle of the lightguide opposite the exit surface is at least partly provided with a diffuse means formed by a nontransparent coating or foil pressed against the mantle of the lightguide, or joined to a diffuse means of the plastic primarily nontransparent material in the process of injection molding of the plastic.
