Abstract: An optical system includes a light guide member and a prism. The light guide member has: an incident surface on which light is incident; and a first surface and a second surface facing each other. The second surface is a light emergent surface. The prism is provided for the first surface and reflects, toward the second surface, the light passing inside the light guide member. The light guide member includes a direct optical path, along which the light that has entered the light guide member through the incident surface is directly reflected from the prism and allowed to emerge from the second surface.

Abstract: An illumination device disposed on a moving body includes at least one main light source, and at least one auxiliary light source disposed in a periphery of the at least one main light source when seen along a traveling direction of the moving body. The illumination device further includes a first light guide disposed adjacent to the at least one main light source, that guides light transmitted from the at least one main light source, and a second light guide that is disposed adjacent to the at least one auxiliary light source, that guides light transmitted from the at least one auxiliary light source. The illumination device also includes an optical component that transmits the light from the first light guide and the light from the second light guide in the traveling direction of the moving body.
