A lighting module able to give a light beam with cut-off line for a motor vehicle headlight, comprising a light source, a reflector, a dioptre serving as an exit lens or an exit lens, and a reflective folder. The light source is combined with a collimator in order to give a beam that can be assimilated to a parallel beam, substantially orthogonal to an exit plane of the collimator. The reflector and the dioptre or lens may be combined in a single piece made from transparent material, and the surface of the reflector and that of the folder means work in total reflection according to an air/transparent material interface.
