Claims

[Scope of utility model registration request]

A light source is arranged 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 a circumferential side part at one end of the periphery, and a side part of the light source corresponding to the circumferential side part. A side lens is provided which is appropriately inclined outward with respect to the optical axis, and the side lens is provided with a prism portion that controls the light from the light source to be light in a direction substantially perpendicular to the side lens,
and reflecting the light from the side lenses to the peripheral side part,
A vehicular lamp characterized in that a total reflection lens is provided on the housing side, the total reflection lens comprising a total reflection surface part provided so as to reflect the light source, and a reflection part that reflects light emitted rearward from the light source to the center part of the lens.
