Abstract
Herein disclosed is a vehicular headlamp. The headlamp comprises a concave light reflector which includes upper and lower light reflecting surfaces each being of a paraboloid of revolution. The upper and lower light reflecting surfaces have respective upper and lower rotation axes which extend forward in parallel with each other and have respective focuses on the axes. The respective focuses are located at respective positions where an imaginary line perpendicular to the rotation axes intersects the same. A lens covers an opening of the concave light reflector. A first light source is positioned at the focus of the lower light reflecting surface, and a second light source is positioned just above the focus of the upper light reflecting surface.
