Abstract
A vehicle headlamp includes a first light source configured to emit first light that is projected to form a first irradiation region, a second light source configured to emit second light that is projected to form a second irradiation region joined to the first irradiation region to extend in a transverse direction with respect to an optical axis, a movable shade configured to move between a position at which light irradiation to a joined region of the first irradiation region and the second irradiation region is shielded, and a position at which the light irradiation to the joined region is permitted, and a controller configured to select one of light distribution patterns that are determined by combinations of turning on and off of the first light source, turning on and off of the second light source, and the positions of the movable shade.
