The rotatable lens is configured such that a light output from the light source is incident via an inner circumferential surface and is output via an outer circumferential surface as an irradiating beam, and a predetermined irradiated area is formed by scanning a space in front with the irradiating beam according to a periodical movement of the rotatable lens.

Abstract: A first lamp unit and a second lamp unit arranged in a given direction are provided, luminous intensity of the second lamp unit in a lamp forward direction is set to be higher than luminous intensity of the first lamp unit in the lamp forward direction, and the first lamp unit and the second lamp unit are turned on sequentially with time difference. Thus, since the first lamp unit and the second lamp unit having different luminous intensity and being arranged in the given direction are turned on sequentially with time difference, it is visually recognized that emitted light flows from one side to the other, and the light is emitted from both the first lamp unit and the second lamp unit that has higher luminous intensity than that of the first lamp unit. Thus, it is possible to ensure high conspicuity in addition to improvement of functionality.
