PURPOSE: To improve visibility at curves. CONSTITUTION: Diffused light distribution pattern WP can be changed with respect to fixed standard light distribution patterns LP and HP, by rotating an upper reflector 1 with respect to a middle reflector 2. Converging light distribution pattern SP can be changed with respect to fixed standard light distribution patterns LP and HP by rotating a lower reflector 3 with respect to the middle reflector 2. As a consequence, visibility at curves is improved. |
