A vehicular lamp including a resin-made plain outer cover that covers the lamp
body. The plain outer cover has an interior lens step (cylindrical step) formed
in a region that faces a gap between an extension element (or a reflector) installed
in the lamp body and the inner surface of a leg portion of the outer cover. The
lens step optically reduces the gap between the leg portion and the extension element
(or a reflector) and thus optically magnifies the leg portion of the outer cover,
allowing the lamp to have a sense of stateliness and a sense of luxury seen in
the lamp that uses a glass-made outer cover.
