Open automotive door alert

摘要

An open door alert system for a vehicle causes an exterior light of the vehicle to flash if one or more vehicle doors are open. A sensor determines if the door, such as a sliding door of a van or minivan, is open. If the door is open, the exterior light flashes on and off to alert drivers of other vehicles that passengers may be entering or exiting the vehicle. Additionally, an interior vehicle light flashes concurrently with the exterior light to alert the driver that the door is open.
