Rope lights were typically sold in long lengths that could be cut to the required length in the field. This allowed an electrician to install long lengths quickly. Markings were provided along the length identifying the location of the end of the series circuit, indicating where the rope light may be cut and terminated. If the rope light was cut anywhere else along its length, an entire circuit of lamps would not light. An installation kit was provided with these products, consisting of connectors for termination and installation instructions.
Since these products were originally intended for installation by an electrician, field cutting and termination was allowed with the understanding that they would be installed in accordance with the applicable electrical installation codes , subject to verification by the regulatory authority. However, in the last decade, rope lights have become increasingly popular as seasonal decorations among consumers and do-it-yourselfers.
Because of the widespread use and installation of these products, the need to update the requirements for rope lights became apparent. UL convened an industry ad hoc committee to assist in the development of a completely new standard for flexible lighting products.
