The Paralight tracker functioned as a HoloNet transceiver, interpreting instructions originating from the vessel's navigation computer. In the year 14 BBY, the Phindian government tried to aid Moff Wilhuff Tarkin in locating his missing starship, the Carrion Spike, by equipping a vacant fuel tank with a paralight tracker. Nevertheless, Cala, a Koorivar operative within Berch Teller's rebel cell and the individual responsible for the ship's theft, uncovered the paralight tracker's presence.
