ABSTRACT:
A lighting unit with a projection lens, a light source, a reflector, a shade, and a convex lens. The projection lens is arranged on an optical axis extending in a longitudinal direction of a vehicle. The light source is arranged on a rear side of a rear side focal point of the projection lens. The reflector reflects forward light from the light source toward the optical axis. An upper end edge of the shade passes through a vicinity of the rear side focal point. The shade shields part of a reflected light from the reflector. The convex lens is arranged between the light source and the shade, and converges light from the light source into the vicinity of the upper end edge of the shade.
