A control unit 20 controls a lighting state of each of radiating portions 11 to 13 in accordance with the determined light distribution pattern, based on data indicative of a state forward of a vehicle. When a light distribution pattern for ADB being selected, the control unit 20 controls a driving portion 15 based on data indicative of a state forward of the vehicle to adjust a rotation angle of the radiating portion 12 for a beam for ADB. In a case of determining to switch a light distribution pattern for ADB to a light distribution pattern for driving, the control unit 20 enables lighting of the radiating portion 13 for a beam for driving on the condition that a rotation angle of the radiating portion 12 for a beam for ADB is confined to an angle in a predetermined range from the front side of the vehicle.
