Claims

[Scope of utility model registration request]

A lamp in which a light source is arranged in a lamp chamber defined by a housing and a front lens, the front lens having a central part facing the light source and a peripheral side part at one end thereof, and a side of the light source corresponding to the peripheral side part. A side lens is provided which is inclined outward with respect to the optical axis, and the side lens has an inner surface so as to control the light emitted from the light source into a substantially flat beam shape in a direction perpendicular to the side lens. Alternatively, a prism portion is formed on the outer surface, and a total reflection lens or a reflective surface is provided on the outside of the side lens to reflect the light that has passed through the side lens toward the peripheral side portion approximately parallel to the side lens. A vehicle lamp characterized by the following:
