Abstract
A vehicular vision system includes at least a sideward-viewing side camera at a side of a vehicle, a rearward-viewing rear backup camera, and a ground illumination light module disposed at the side of the vehicle and including at least one light emitting diode and a freeform optic. The vehicular ground illumination light module, when the light emitting diode is electrically powered so as to emit light through the freeform optic, illuminates a ground region at that side of the vehicle. The illuminated ground region includes an illuminated side ground region at least partially along the side of the vehicle and an illuminated rearward ground region rearward of a rear portion of the vehicle. The illuminated ground region is at least in part viewed by the sideward-viewing side camera and the rearward-viewing rear backup camera. A portion of the illuminated side ground region is illuminated with a luminance of at least 10 lux.
