ABSTRACT:
An automotive marker lamp has a lens on which there are formed both convex and concave semicylindrical steps, all extending parallel to each other. Each convex step creates the real image of the light source outside lens whereas each concave step creates the virtual of the light source inside the lens. Thus the lamp gains a depth image when glowing.
