the inner one-color light source and the inner other-color light source being arranged one above the other in an inward position in the vehicle width direction, the outer other-color light source and the outer one-color light source being arranged one above the other in an outward position in the vehicle width direction; and at least two light guide members (111, 121) each guiding light of each of the respective light sources (90, 91, 100, 101) from one end toward the other end, the light being launched into a light entrance (112, 122, 114, 124) at the respective one end, wherein the light guide members (111, 121) are provided in at least two rows in a vehicle up-down direction, the light guide members (111, 121) comprising an upper light guide member and a lower light guide member, the upper light guide member being placed to provide a connection between the inner one-color light source and the outer other-color light source, such that: - when the upper light guide member is used for light emission in one color, the inner one-color light source emits light, - when the upper light guide member is used for light emission in the other color, the outer other-color light source emits light, the lower light guide member being placed to provide a connection between the inner other-color light source and the outer one-color light source, such that: - when the lower light guide member is used for one-color light emission, the outer one-color light source emits light, and - when the lower light guide member is used for light emission in the other color, the inner other-color light source emits light; characterized in that the light sources (90, 91, 100, 101) enabling launch of respectively different color lights defined by the one-color light and the other-color light are mounted at both ends of the light guide members (111, 121), and in that, when the light sources (90, 100) emitting the light of one color are lit, the light sources (91, 101) emitting the light of the other color are extinguished. light sources (90, 91, 100, 101) including semiconductor devices;
