Lighting mount for interior-lighted signage and method of retrofitting a lighted sign

A method of retrofitting an internally-lighted sign that is fitted with one or more gas-discharge lamps, said method comprising:

• removing the one or more gas-discharge lamps from between one or more respective pairs of gas-discharge lamp couplings positioned directly opposite from one another along an interior of the sign;
• positioning and frictionally engaging respective end caps at opposite end portions of an elongate support member, wherein the end caps are made of electrically insulative material and do not retain any electrical conductors along or through said end caps for powering said plurality of electric lamp units;
• positioning one or more electric lamp units along the elongate support member;
• and
• engaging each of the end caps in a non-conductive manner with a respective one and only one of the gas-discharge couplings or with a respective one and only one replacement coupling to thereby position the end caps, the elongate support member, and the electric lamp units between the gas-discharge lamp couplings or replacement couplings that are positioned directly opposite from one another.

A retrofit kit for an internally-lit sign, the sign having a framework and at least one display sheet that is at least partially translucent, said kit comprising:

• an elongate support member for supporting a plurality of electric lamp units, said elongate support member having opposite end portions;
• a plurality of low-voltage lamp units for positioning along the elongate support member;
• a pair of end caps configured to frictionally engage the opposite end portions of the elongate support member, each of the end caps having one and only one mechanical coupling element at an outwardly-facing side thereof, wherein the end caps are made of electrically insulative material and do not retain any electrical conductors along or through said mechanical coupling element for powering said plurality of electric lamp units;
• and wherein respective mechanical coupling elements of the pair of end caps are configured to non-electrically engage respective individual standard mounts located directly opposite one another at the framework that are for supporting a single gas-discharge lamp at the framework.
