Claims

[Scope of utility model registration request]

This is a lamp in which a light source is placed in a lamp chamber defined by a housing and a front lens, and the front lens has a central part facing the light source and outer peripheral parts on both sides of the central part, and the front lens has peripheral parts on both sides of the light source corresponding to the outer peripheral part. A side lens is arranged approximately parallel to the optical axis, and the side lens has an inner prism and an outer prism arranged so that the side light from the light source becomes a parallel beam in a direction approximately perpendicular to the side lens. and a total reflection surface portion configured to reflect the light that has passed through the side lenses to the outer peripheral portion of the front lens, and a total reflection surface portion configured to reflect the rear light from the light source to the center portion of the front lens. A vehicular lamp characterized in that a total reflection lens consisting of a reflective surface is disposed to surround the side lens.
