Abstract
Emergency deceleration warning devices which may also be manually activated to provide a warning in situations where abnormal deceleration is not involved. The disclosed devices are self-contained units which include: (1) a flasher which is highly visible, even in bright daylight; (2) a circuit for turning the flasher on and off; and (3) a simple, enclosed decelerometer for enabling the flasher-operating circuit when a vehicle equipped with the warning device is decelerated at an abnormal rate.
