Claims

[Scope of Claim for Utility Model Registration] A lamp in which a light source is disposed within a lamp chamber defined by a housing and a front lens, wherein the front lens has a central portion facing the light source and a peripheral side portion at one end of the periphery; A side lens is arranged substantially parallel to the optical axis on the side of the light source so as to correspond to the peripheral side part, and a total reflection surface part so as to reflect the light from the side lens to the peripheral side part, and the light source. A total reflection lens is provided on the housing side, and the side lens has an optical axis and an inner surface that reflects the light from the light source toward the center of the lens. A vehicular lamp comprising: a direct-ray prism that controls light beams in a substantially perpendicular direction; and a prism portion on the outer surface of the prism that allows light to enter the entire area of the total reflection surface of the total reflection lens.
