ABSTRACT:
A vehicle warning and help apparatus and method comprising a light box electrically and removably connected to a control panel. The light box comprises a red light, yellow light, transceiver, power supply, inertial switch, and momentary contact switch. The control panel comprises a continuous yellow switch backlit when ON by a continuous yellow switch light, a three-flash yellow switch backlit when ON by a three-flash yellow switch light, a red switch backlit when ON by a red switch light, and a horn. In operation, a transmitting vehicle warning and help apparatus sends a signal on a red frequency, a yellow frequency, or both. The transmissions are received by a receiving vehicle warning and help apparatus, and the receiving vehicle warning and help apparatus sounds its horn and illuminates a combination of its continuous yellow switch light, three-flash yellow switch light and red switch light, thus communicating a condition of maximum alert, minimum alert, momentary warning, or official alert. In addition, the momentary contact switch may be used to transmit Morse code messages. The light box is removable from the control panel to permit a distressed motorist to carry the light box with him when seeking help, while the light box continues to transmit help requests and/or Morse code messages, and visual signals.
