Headlight system for a vehicle

A front-lighting system for a vehicle, comprising:

• a first light source, a second light source, a transparent shutter, and a secondary optics,
• a first primary optics arranged to receive light from the first light source and project it onto the transparent shutter and the secondary optics, the secondary optics arranged to receive light from the first primary optics and the transparent shutter and project it onto a road in front of the vehicle, and
• a second primary optics arranged to receive light from the second light source and project it onto the transparent shutter, the transparent shutter arranged to receive light from the first light source via the first primary optics and prevent a lower part of it from entering the secondary optics, the transparent shutter further arranged to receive light from the second light source via the second primary optics and project it onto the secondary optics, the transparent shutter comprising:
• a flat or freeform light out-coupling surface, and
• one surface that comprises micro-optical structures, borders the light out-coupling surface, and is arranged to refract towards the secondary optics at least part of the light received by the transparent shutter from one or both of the first light source and the second light source which part of the light otherwise without the micro-optical structures would be totally internally reflected by a corresponding flat surface bordering the light out-coupling surface and would not reach the secondary optics.
