Abstract

The enhanced auxiliary signaling device of the present invention includes a housing mounted on the rear of a vehicle with a control unit electrically connected to the vehicle electrical system and to a display panel on the housing to display various alphanumeric and graphic messages in response to activation of signals in the vehicle electrical system. The activation of a vehicle turn signal will cause a first alphanumeric message to be displayed along with a first graphic display. The second turn signal will display the first alphanumeric message along with a second graphic display. Activation of both turn signals will activate a second alphanumeric message, simultaneous with the first and second graphic displays. The activation of the vehicle brakes will activate a second alphanumeric message and a third graphic display. The control unit includes a microprocessor which prioritizes message displays, such that only a signal alphanumeric message display is displayed simultaneous with one or more graphic displays.

Claims

1. An auxiliary signaling device for electrical connection to a vehicle'"'"'s electrical system, comprising:

a housing with means for attaching the housing to the rear of the vehicle;

a control unit within said housing having means for electrically connecting the unit to the electrical system of the vehicle;

said housing including a display panel with visual display means responsive to electrical signals from said control unit;

said control unit responsive to signals from said vehicle electrical system to activate visual message displays on said display panel;

said visual message displays including;

a first alphanumeric message displayed in response to a signal caused by the activation of one of two vehicle turn signals; and

a second alphanumeric message displayed in response to a signal caused by the activation of vehicle brakes;

said control unit including a microprocessor programmed to prioritize said alphanumeric messages, to display only one of said alphanumeric messages in the event that more than one signal is received from the vehicle electrical system;

said visual message displays further including a first graphic displayed in response to a signal caused by the activation of a first of two vehicle turn signals, said first graphic displayed independently of the display of any of said alphanumeric messages.

2. The device of claim 1, further comprising a third alphanumeric message displayed in response to the activation of vehicle hazard lights.

3. The device of claim 2, further comprising a fourth alphanumeric message displayed in response to the activation of a reverse gear of the vehicle.

4. The device of claim 1, further comprising a second graphic display displayed in response to a signal caused by the activation of a second of two vehicle turn signals, said second graphic display displayed independently of the display of any of said alphanumeric messages.

5. The device of claim 4, wherein said first and second graphic displays are both displayed in response to the activation of vehicle hazard lights.

6. The device of claim 5, further comprising a third graphic display displayed in response to a signal caused by the activation of the vehicle brakes, said third graphic display displayed independently of the display of any of said alphanumeric messages and independently of the display of any other of said graphic displays.
