Title: Vehicle headlight with polarized and non-polarized light emission

Abstract: In order to improve the near-field illumination provided by motor vehicle headlights having a polarized light output, the headlight is provided with mirrors which intercept non-polarized light from the parabolic reflector and direct it through diffuser plates for near-field illumination alongside the central polarized beam. The rear surface of mirrors already present for bending the central polarized beams is made reflective and a second set of plane parallel mirrors is provided for bending the light reflected from the rear surfaces of the first set of mirrors back into the direction of the optical axis.
