  • Patent number: 4825191
    Abstract: An auxiliary multi-purpose signaling indicator for a vehicle is constructed of three elongate sections which include a central section which lights when the brake of the car is depressed and left and right sections which flash for indicating left and right turns. Normally the three sections are arranged along a straight line and operate in a mode which is conventional for brake and turn indicators. In case of an emergency, the left and right turn sections of the signaling device may be bent toward each other to configure the device into a triangular shape. Each side of the triangle contains one of the indicators. The distal ends of the left and right sections are linked mechanically and electrically such that activation of the emergency flasher of the vehicle provides a triangularly shaped flashing light beam.
