ABSTRACT:
A vehicular headlamp apparatus 1 is provided with a first and a second light-emitting portion including a common light source 3 or a plurality of light sources 3 and 3′. The first light-emitting portion 2_1 forms a base beam by normally lighting the light source 3 to use emission light from the light source. The second light-emitting portion 2_2 is caused to emit an auxiliary beam for supplementing the light distribution of the base beam made available by the first light-emitting portion 2_1. The distribution, the quantity of light or light color of the light emitted from the first light-emitting portion 2_1 is varied with the travel condition or travel environment of a vehicle.
