Abstract: A lighting module for a motor vehicle includes a first light source and a first collimator for generating a first light beam of “low beam” type in collaboration with a first projection lens. Also included are second and a third light sources, the second light source collaborating with a second collimator to generate a first beam complementing the first light beam in order to form a second light beam of “high beam” type. In order to reduce the visibility of a cut-off zone in the second beam, the third light source collaborates with a third collimator and/or a second projection lens in order to form a second complementary beam which at least partly overlaps the cut-off zone. A front headlight for a motor vehicle can include such a lighting module.
