HEADLIGHT FOR VEHICLE

A headlight () includes a lamp unit () including: light sources (R,G,B) that emit laser light; and phase modulation elements (R,G,B) that diffract the laser light emitted from the light sources (R,G,B) with a phase modulation pattern that is changeable, and emit light of a light distribution pattern based on the phase modulation pattern. The lamp unit () adjusts a total luminous flux amount of light emitted from the lamp unit () according to the light distribution pattern.
