Abstract
The present invention relates to a vehicle headlight that ensures maintaining usage efficiency of a light of the vehicle headlight while improving visibility of an irradiation target on a road by a headlight light from a host vehicle. A vehicle headlighthaving a headlight unitforming a light distribution pattern by projecting a light Bfrom a light sourceahead includes a polarized light generatora first headlight unitand a second type headlight unitThe polarized light generatorgenerates a first and a second polarized lights (BB) by the light Bfrom the light sourceThe first headlight unitindicates main light distribution patterns (LaLb) by a first polarized light Bahead. The second type headlight unitscans with a second polarized light Busing a scanning mechanismand indicates ahead auxiliary light distribution patterns (LaLb) irradiating a range narrower than the main light distribution patterns (LaLb).
