ABSTRACT:
A vehicular lamp which includes a lamp body having a front opening, a lens coupled to the front opening of the lamp body, a light source disposed within a lamp chamber defined by the lamp body and the lens, and convex and concave fish-eye lens steps arranged in a line direction thereof, wherein because step portions are formed at a boundary of the convex and concave lens steps and the convex lens steps and the concave lens steps are arranged to shift by half a pitch in a column direction thereof, optical images created by the convex and concave lens steps are focused on different points from each other in the front-rear direction of the lens or the lamp, to create an impression of the deep, three dimensional lamp inside.
