Abstract

A headlight includes light sources, and phase modulation elements that diffract lights incident from the light sources with changeable phase modulation patterns. The lights diffracted by the phase modulation elements are emitted with a low beam light distribution pattern that is a predetermined light distribution pattern based on the phase modulation patterns. A projection region on which zeroth order lights, that are emitted from the phase modulation elements without being diffracted by the phase modulation elements, among the lights incident on the phase modulation elements, are projected is located within a range where a driver's view of a vehicle is obstructed by the vehicle.
