Patent ID: 7696865

Claim:
An electronic message board for enabling a driver of an existing vehicle to convey a predetermined visual message to another driver of another existing vehicle during driving conditions, said electronic message board comprising: a housing removably affixed to an interior surface of a selected window of the vehicle; a light display removably interfitted within said housing; and means for selectively actuating said light display, said selective actuating means being located within an interior of the existing vehicle and in close proximity to the driver during driving conditions; wherein said housing comprises: a back wall having front and rear planar surfaces respectively; a first electrically conductive plate having a planar rear surface directly attached to said front surface of said back wall, said first conductive plate having a longitudinal length equal to a longitudinal length of said back wall; and a transparent front plate directly connected to a front surface of said first conductive plate along a major portion of an outer perimeter thereof such that a slot is formed between said front plate and said front surface of said first conductive plate, said front plate being coextensively shaped with said first conductive plate; wherein said first conductive plate comprises a plurality of electrically conductive detents directly connected to said front surface of said first conductive plate and protruding forwardly into said slot of said housing; a second electrically conductive plate having front and rear surfaces respectively, said rear surface of said first conductive plate being removably attached directly to said front surface of said first conductive plate; a light emitting diode array directly and permanently attached to said front surface of said second conductive plate, said light array being contiguously situated along said front surface of said second conductive plate; a first magnetic frame directly and permanently attached along said outer perimeter of said front surface of said second conductive plate such that said light array is disposed within said first magnetic frame, said magnetic frame having a centrally registered opening formed therein; a transparent faceplate having predetermined indicia formed in a front surface thereof; and a second magnetic frame directly and permanently attached to a rear surface of said faceplate and along an outer perimeter thereof, said second magnetic frame being coextensively shaped with said first magnetic frame; wherein said first magnetic frame and said second magnetic frame are removably mated together, said light array being intercalated between said second conductive plate and said faceplate when said first and second magnetic frames are mated together; wherein said light display is interfitted within said slot of said housing during operating conditions.
