Abstract
Official abstract text for this publication.
A vehicular headlamp has a projection lens, a light source disposed behind a rear focal point of the projection lens, and a reflector that reflects light from the light source forward. The vehicular headlamp forms a forward light distribution pattern. The vehicular headlamp includes a plate-like shade having a front-end portion positioned in the vicinity of the rear focal point of the projection lens to form a cut-off line of the forward light distribution pattern. The shade extends rearward and obliquely downward from the front-end portion. An overhead sign reflective surface is provided on a lower surface of the shade. The overhead sign reflective surface reflects light from the reflector toward the projection lens to form a part of an overhead sign distribution pattern. A dark portion forming portion is formed on the overhead sign reflective surface.
