Vehicle headlight

Abstract

A vehicle headlight (1) includes a lamp unit (10) capable of changing a light distribution pattern of emitted light, and a control unit (CO) that controls the lamp unit (10) based on information input from a detection device (120) that detects a predetermined object located in front of a vehicle (100). The control unit (CO) controls the lamp unit (10) to emit light having a light distribution pattern (PH) of a high beam including an additional light distribution pattern (PAH) in a case where the predetermined object is not detected, and in a case where the predetermined object is detected, controls the lamp unit (10) so that a light amount of a first region (91a, 91b, 91c) overlapping at least a part of the predetermined object in the additional light distribution pattern (PAH) decreases and a light amount of a second region (92) different from the first region (91a, 91b, 91c) increases at a predetermined magnification or by a predetermined amount, as compared with the case where the predetermined object is not detected.
