ABSTRACT:
Illuminated message displays improve improving traffic safety by notifying drivers of the turning characteristics of semi trailers. Lamps mounted on the front of a circuit board and controlled by a microprocessor display a pattern of messages to warn motorists of the need to not be adjacent to a semi trailer when it makes a right hand turn, to notify motorists when a right hand turn is imminent, and to thank motorists for their cooperation. A wire connects the microprocessor and circuit board to the taillights of a semi trailer so that they are powered when the taillights are turned on. Circuit board holders releasably attach the circuit board to the rear door of a semi trailer. A pair of brackets with end caps are attached to the bottom of the rear bumper of a semi trailer to hold the circuit board and plates safely out of the way when the rear door of the semi trailer is opened.
