<p>PROBLEM TO BE SOLVED: To provide a constant irradiation range in a horizontal direction for securing a wide visual field necessary for safe driving by turning an inner lens in a headlamp. SOLUTION: An inclination of a two-wheeler body to the right and the left is detected by a gyro-sensor 1. A signal from the gyro-sensor 1 flows to a processing circuit 5 to supply a signal to actuate a servo motor 4. The servo motor 4 turns a lens 3 to a position of a direction and an angle by the signal. Light flux from a light source 11 and a reflection mirror 10 is bent in a cut direction of the turned lens, thereby light is projected in a horizontal and constant range to a road surface.</p> |
