ABSTRACT:
A vehicular headlamp which radiates a beam forward in a predetermined low-beam light distribution pattern using a projection-type lamp unit and with which visibility to the sides of a vehicle is improved without having a significant effect on the formation of the low-beam light distribution pattern. A first additional reflector for reflecting light from a discharge light source of a discharge bulb forward is disposed below a discharge bulb of the projection-type lamp unit. A second additional reflector for reflecting reflected light from the first additional reflector to one side is provided in front of the first additional reflector. An additional light distribution pattern that partially overlaps a side portion of the low-beam light distribution pattern is formed, thereby providing improved illumination of road zones to the sides of the vehicle. Although a lower portion of a reflector is cut away in order to receive both additional reflectors, this does not significantly affect formation of the low-beam light distribution pattern.
