1. A method for installing at least one light emitting diode light comprising; (a) providing a sign assembly having at least one translucent plate, a frame structure securing a perimeter of the at least one translucent side plate, the frame structure having an interior surface having at least two opposite sides spaced from each other, at least two electrical sockets, each for receiving connectors (b) providing at least one light emitting diode light device having a passageway extending longitudinally therethrough and a first end and a second end, and a plurality of light emitting diodes mounted on an exterior surface of the device, the first end and second end including a connector adapted for engaging with the at least two electrical sockets; (c) opening the sign assembly so as to access the at least two electrical sockets; (d) disconnecting wiring extending between the electrical sockets on either side of the fluorescent tubes and removing the fluorescent tube (e) optionally rotating at least one electrical socket cap so that the plurality of light emitting diodes will face the at least one translucent side plate; and (f) installing the at least one light emitting diode light device so that the connectors are positioned in electrical communication with the electrical sockets.
