LMT Mercer had the consumer in mind when they designed their lighting components! These no-hassle harnesses quickly connect LED lights to the dimmer, transfomer, a splitter, or T-connector. Choose from 2 ft, 5 ft, 7 ft or 9 ft harnesses, each sold individually. Each extension cable has one male fitting and one female fitting to take the guesswork out of LED lighting installation. Be sure to firmly connect each fitting (a gap should not be visible between the connector ends). Harnesses can be installed beneath the deck or can be run inside post sleeves or rails.
