an internal face of the screen, which face is situated facing said at least one lighting module, is equipped with a plurality of optical modules that scatter the light emitted by the at least one light source toward the outer lens,
the outer lens makes a first angle of 60° to 100° with the optical axis of said at least one lighting module,
the screen makes, with the optical axis of said at least one lighting module, a second angle such that part of the cone of light from the beam of light, which part is situated beneath the optical axis when the headlamp is in a position of use, is reflected by the screen toward said lighting module and above said lighting module.
