Abstract: A lighting system includes a first elongate channel configured for mounting to a structure, a second elongate channel configured for being temporarily coupled to the first elongate channel and forming a substantially enclosed elongate space between the first and second elongate channels. A plurality of led lights, each having a translucent watertight housing, at least one led and a integrated circuit within the translucent housing, are coupled to the second elongate channel with each of the translucent watertight housings exposed through the second elongate channel. A controller is electrically connected to a plurality of segments of wire to communicate with each of the plurality of integrated circuits and has a plurality of programmable functions, each function providing at least one of a desired light color for each of the plurality of led lights, duration of illumination and timing of illumination.
