By inserting a light source bulb into a reflector from a side thereof at a position apart downwardly from an optical axis, it is made possible to use an area situated on a side of the optical axis effectively for controlling the light distribution of a vehicle headlamp. In addition, by providing an additional reflector between the light source bulb and a shade for reflecting light from a light source laterally outwardly and diagonally forward of a vehicle through a gap between the reflector and a projection lens, a diffused area of a low beam light-distribution pattern is illuminated brightly and the diffused area is expanded laterally outwardly of the vehicle.
