Beschreibung
Zusammenfassung:	A projector type lighting device (1) includes a shading plate (4) having an asymmetrical portion formed on one side of the shading plate depending on the given light distributing propertoes of the lighting device to prevent a driver from being unpleasantly irradiated with dazzling light emitted from a vehicle running in the opposite direction, and the asymmetrical portion is fully covered with the shading portion of an auxiliary shutter (6). When a road sign or the like standing upright on a road shoulder is visually recognized by the driver, the auxiliary shutter (6) is linearly displaced in the downward direction to reach the lowermost position so as to allow the asymmetrical portion to become operative. Alternatively, a substantially circular auxiliary shutter including a shading portion having a sector-shaped countour may turnably be displaced in one of the clockwise and anticlockwise directions. Otherwise, the shading plate (4) itself may serve as an auxiliary shutter in such a manner as to turn about a center axis of the lighting device (1) in one of the clockwise and anticlockwise directions.
