CAR DRIVER CAN NOW FLASH SIGN FOR HELP (Oct, 1934)
CAR DRIVER CAN NOW FLASH SIGN FOR HELP
Attacked by hold-up men or kidnapers while in his car, a driver using a Detroit inventor’s new alarm signal may appeal to police or passing motorists for help. The signal is lettered with the word “Help.” When not required, it folds up out of sight. When danger threatens, the driver pushes a button and the signal drops down into plain view.
