The present invention relates to a lighting module for a vehicle headlight which produces a lighting beam of the type having a cut-off, and which is particularly well adapted for use with light emitting diodes. The module has a first reflector which includes an elliptical surface for reflecting light rays and having an elliptical generatrix, together with at least one first light source which is arranged in the vicinity of the first focus of the said first reflector. The module also includes: a second reflector, for producing a first portion of the cut-off beam and having an optical axis, which passes through the second focus of the first reflector and at right angles to the optical axis of the said first reflector; a third reflector producing a second portion of the cut-off beam and having an optical axis passing through the second focus of the said first reflector and at right angles to the optical axis of the said first reflector; and a fourth reflector or bender, which is arranged between the said second reflector and the said third reflector. The bender has an edge referred to as a cut-off edge, which is arranged close to the said focus of the said first reflector, in such a way as to form the cut-off in the lighting beam, together with a reflective top face which contains the said optical axes of the second and third reflectors respectively.
