A vehicular ground illumination light module includes at least one light emitting diode and a freeform optic disposed in front of the emitting diode. The vehicular ground illumination light module, when disposed at a side of a vehicle, and 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 rearmost portion of the vehicle. The illuminated ground region is at least in part within the fields of view of a sideward-viewing side camera and a rearward-viewing rear backup camera disposed at the vehicle. A portion of the illuminated side ground region is illuminated with a luminance of at least 10 lux.
