The Paralight tracker was a type of HoloNet transceiver that parsed commands from the ship's navigation computer. In 14 BBY, the Phindian authorities attempted to help Moff Wilhuff Tarkin track down his stolen starship Carrion Spike by fitting an empty fuel with a paralight tracker. However, the paralight tracker was discovered by the Koorivar Cala, a member of Berch Teller's rebel cell, who had stolen the ship.
