If you are joining multiple strips of tape lighting, you may need more wire than is included in the kits.
Four-conductor wire is required for connections involving color-controlled lighting, color-controller to lights and light to light.
Solid-core outdoor-rated wire is supplied in a 26.2' (8m) roll. The 20 gauge four-conductor wire may be preferred by those that choose to solder the connections between tape lighting and wire. Rated for indoor/outdoor application and direct burial.
