The actuatorcontrols a light distribution of light that is illuminated from the light source. The lamp control device LC controls lighting-up of the light sourceand driving of the actuator. The lamp control device LC includes a current control deviceand an actuator control device. The current control deviceoutputs a constant current. The actuator control deviceconnects the actuatorto the light sourcein series based on a predetermined signal so that the constant current, which is output from the current control device, flows through the light sourceand the actuator
