Abstract: A lamp unit for illuminating a front through an outer lens includes a first light source disposed on a back side of the outer lens, a second light source disposed on the back side of the outer lens, a first light guide body configured to guide light from the first light source to the outer lens, and a second light guide body configured to guide light from the second light source to the outer lens. The second light guide body overlaps the first light guide body from a front side in a front view. The first light guide body protrudes outward from the second light guide body. A part of light from the first light guide body is transmitted through the second light guide body and guided to the outer lens.

Abstract: A lamp unit in which an opening of a unit case is covered with an outer lens is provided. The lamp unit includes a first inner lens provided inside the outer lens, a second inner lens provided inside the outer lens, a first light source facing an incident surface of the first inner lens, and a second light source facing an incident surface of the second inner lens. A space inside the first inner lens and a space inside the second inner lens are continuous. At least a part of the incident surface of the second inner lens is disposed in an irradiation range of the first light source.
