PROBLEM TO BE SOLVED: To improve visibility in the front of a head lamp by shading a light going toward the display part lower region of a front lens by a shade as an automobile marker lamp. SOLUTION: The upper edge part of a shade 40 extended left and light in the front side of a bulb 34 as a light source is positioned on an optical axis L and a light emitted from the filament of the bulb 34, reflected by a reflector 32 and sent toward the lower region 12b2 of a display part center O3 when the shade 40 is not provided and a vertical light sent from the filament of the bulb 34 to the lower region 12b2 are shaded. Accordingly, the amount of emitted light is reduced in the lens lower region 12b2 , thus illumination by a signal lamp 30 on a road surface C in the car body side is reduced more than the limit P1 of an illuminating region A by a head lamp 18 in the vicinity of the car body and therefore, no relative darkening of a region A1 in the vicinity of the car body on the road surface illuminated by the head lamp is felt by a driver. That is, the display center O3 of the signal lamp 30 becomes a position O'3 by providing the shade 40, this part is not illuminated by the lamp 30 in the side C in the vicinity of the car body and thus the region A illuminated by the head lamp 18 becomes brighter. |
