A method or system, and the appropriate structural components therefor to allow for readily identifying which particular coded load side conductors of a ballast feed which particular lamp sockets and thus lamps of an advertising sign illuminated by florescent lamps. Coded markers indicative of particular coded load side conductors of the ballast are placed on or adjacent each lamp socket within the open interior of the sign to allow for the quick identification of the sign wiring circuitry without the need to remove lamps or an excessive number of wire raceway covers. In a preferred embodiment, the coded markers are durable, inexpensive to manufacture, readily attachable, readily changeable yet cannot inadvertently be dislodged, and are viewable from generally any angle once a translucent display panel of the sign has been moved to expose the sockets, lamps and adjacent raceways within the interior of the sign.
In combination, an advertising sign having opaque wire raceways containing wiring connecting color-coded load side wires of a ballast within said sign to lamp sockets supported by said raceways, said lamp sockets having a single base each having a front surface for supporting florescent lamps within said sign, therebeing a plurality of generally flat panel color-coded markers each having a central opening, said color-coded markers being affixed one said color-coded marker adjacent the front of each of said lamp sockets, therebeing a single base of each of said lamp sockets inserted within said central opening of the adjacent said color-coded markers, said color-coded markers each being of a color equivalent to a particular color of said color-coded load side wires such that a particular color coded marker adjacent a particular one of said lamp sockets will allow visual detection of which said color-coded load side wires of said ballast feeds said particular one of said lamp sockets of said sign.
