VEHICLE HEADLIGHT

A vehicle headlight (1) includes: a second light source unit (40) that includes second light emitting units (43); an actuator (50) that adjusts a direction of light emitted from the second light source unit (40); and a controller (CO), in which the controller (CO) switches the second light emitting unit (43) that emits the light having the highest intensity to another second light emitting unit (43), and controls the actuator (50) to change a direction of second light emitted from the second light source unit (40) in such a way that a region (110) where the intensity of the light is highest in a light distribution pattern (103) after the switching approaches a region (110) where the intensity of the light is highest in the light distribution pattern (103) before the switching.
