The present invention is concerned with a lighting module for a vehicle headlight for giving a light beam of the cut-off type, particularly one which is adapted to use with light-emitting diodes. The module has a second reflector having a substantially elliptical surface for reflecting light rays and at least one light source arranged close to the first focus of the first reflector. The module also includes a second reflector for producing the cut-off or dipped output beam, the focus of this reflector being arranged close to the second focus of the first reflector. The module further includes a third reflector or bender, having a reflective top face and being situated between the first and second reflectors. This third reflector has a cut-off edge arranged close to the second focus of the first reflector, whereby to form the cut-off within the light beam. The light source is a light-emitting diode.
