A lighting track apparatus includes elongated colored tubes which are easily bent into stable curved shapes to custom shape and fit sections of the apparatus into a track lighting system. Plural elongated electrical conductors are mechanically flexible and able to support low voltage lighting currents without significant temperature rise. An elongated non-conducting mechanical support is highly flexible so as to accept the shape of the tubes when bent. It engages with the tubes and the electrical conductors, whereby, the apparatus is easily formed into a curved shape that retains a selected curvature. A lamp or other appliance can be mounted on the apparatus, electrically contacting the conductors for power. The mechanical support is transparent so that the tubes may be seen.
