Abstract: A traffic sign having one or more easily replaceable LED assemblies that can easily be removed or replaced and that make reliable water resistant electrical connection with one or more suitably-designed LED holders, which are installed in various locations as desired on the traffic sign or structure, is disclosed. A control circuit that supplies direct current at suitable levels of DC voltage and DC current to the one or more LED holders that are connected together using series, parallel or combination series and parallel wiring connections in order to provide electrical power to the one or more LED assemblies is provided. Wherein the one or more LED holders also include compensation circuits that enable any failed LED assembly to be electrically bypassed so that the control circuit then automatically adjusts the DC current or DC voltage levels supplied to the remaining traffic sign LEDs so that the remaining LED Assemblies continue to operate properly.
