A vehicular LED assembly is provided that includes a plurality of vehicular LED modules, each comprising: a lens with a canted input surface and an exit surface; a bezel surrounding the lens; and an LED light source positioned to direct incident light through the input surface. The input surface comprises a plurality of near-field lens elements for shaping the incident light into a collimated light pattern emanating from the exit surface. Further, the plurality of optical elements may be configured in a step-wise pattern defined by a sweep angle.
