Abstract
An automobile signalling system includes a programmable processing unit or computer mounted in the vehicle near the driver's station. The unit has a key board and a pre-edit screen for displaying an input from the key board. An output from the processing unit is passed to a light emitting diode display unit mounted in the rear window of the vehicle to cause the LED display unit to produce an illuminated representation of the matter appearing on the screen of the processing unit. Output from the processing unit to the display unit is controlled by the braking system of the vehicle so that a message may be displayed on the display unit only when the brakes of the vehicle are activated.
