The present invention relates to a radar apparatus that forms multiple digital beams based on reflected waves of a transmitted radio wave. Hence, it is possible to reduce the size of the first pumping device and the second pumping device. The driver-side camera and the passenger-side camera are part of a multi-camera vision system of the vehicle, and the multi-camera vision system has a display device that is operable to display images for viewing by a driver of the vehicle. The air columns serve as resonators to muffle noise. The multi-plate lighting fixture may be manually controlled or automated.
