ABSTRACT:
A rearwardly facing three-light display of a parked van to inform an approaching motorist if one, both or none of the rear doors are open, using to advantage lights that are illuminated in the display and also lights, although illuminated, that are not seen by the approaching motorist because of being masked from view by an open door, resulting in three possible light displays which, as a result of driver education, will inform the approaching motorist of the open and closed condition of the rear doors of the parked or stationary van.
