The mark consists of the configuration of the side window of a stretched automobile with coach lights mounted on the inside of the window, rather than on the outside of the automobile, and with the window comprising a single piece of glass supported by external structures on each end and having three areas, one on each end and one in the middle, on which the interior surface of the glass is covered with an opaque black covering broken by apertures that allow the lights to shine through to the outside of the automobile. The dotted outlines are not part of the mark but are merely intended to show the position of the mark and features that are not otherwise used as part of the mark.
