Abstract: A communication system and a method for communicating simple coded messages from one vehicle to another are provided. The communication system includes a signaling module that includes a light source configured and placed so that the light source is visible to occupants of other vehicles. The system includes a control module in communication with the signaling module that is readily accessible to the driver or other occupant of a vehicle. Responsive to the selection of one of a series of possible messages by the driver or occupant, the control module causes the light source to turn on and off in a predetermined sequence of flashes. The predetermined sequence of flashes represents a code corresponding to the selected message. The messages associated with use of the communication system are selected for enhancement of safety and to avert the negative responses associated with road rage.
