ABSTRACT:
An electric power driven sign raiser mounted inside a vehicle bvelow and inside a rear window. The unit is electrically conneced to be activated when the brake light come on with actuation of the brakes. Upon actuation an electromagnet and an electric motor are energized with the electric motor driving a sign lever up to the raised state with the sign showing through the rear window to a position where a switch is thrown cutting off power to the electric motor. The electromagnet holds the sign in the raised position for following drivers to see through the rear window and then when the vehicle brake pedal is released the electromagnet is de-energized and the sign falls back down to its lowered out of sight state ready for reactivation raising with the next application of the vehicle brakes.
