Abstract
A motor-bicycle head lamp includes a reflector formed in a spheroidal shape; a convex lens disposed in front of the reflector; and a shade disposed near a focal point of the convex lens substantially midway between the reflector and the convex lens. The shade is rotatable around the optical axis of the motor-bicycle head lamp in accordance with a slant angle of the body of the motor-bicycle. A slant angle sensor device is provided to rotatably drive the shade.
