とを特徴とするプロジエクタ型前照灯。 A projector in which a light source bulb is installed near the focal point of a reflecting mirror, the light emitted from the light source bulb is reflected by the reflecting mirror and focused near a shade having a cut line, and the reflected light is projected forward by a convex lens. In this headlamp, a spheroidal auxiliary reflector with a second focal point located near the light source bulb is provided, and an auxiliary light source bulb is installed near the first focus of the auxiliary reflector. Features a projector type headlight.
