Claims

[Scope of utility model registration request]

This is a lamp in which 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 outer peripheral parts on both sides of the central part, and the front lens has a central part facing the light source and an outer peripheral part on both sides of the central part. A side lens is provided on the side, which forms a prism that is inclined outward with respect to the optical axis and controls the side light from the light source into substantially parallel light, and the light that has passed through the side lens is converted into a lens. The side lens is surrounded by a total reflection lens having a total reflection surface portion that totally reflects the light toward the outer periphery on both sides of the lens, and a total reflection surface that completely reflects the rear light from the light source toward the center portion of the lens. A vehicle lamp characterized by being installed as follows.
