Abstract
A vehicular lamp includes a first light source that emits light for forming a first distribution pattern, a second light source that emits light for forming a second distribution pattern that is added to the first distribution pattern, and a light guide member disposed in front of the first light source. The light guide member includes a first incidence surface on which the light emitted from the first light source is incident, a total reflection surface by which a part of the light incident from the first incidence surface is totally reflected, and a first emission surface from which the light totally reflected by the total reflection surface is emitted toward the lamp front. A part of the light emitted from the second light source passes through the total reflection surface and the light guide member and is emitted from the first emission surface toward the lamp front.
