An airport inset light overlay protection plate apparatus, comprises (a) a light fixture support for placement as a partially embedded support for a light fixture in an airport runway, taxiway, or other aircraft ground traffic area; (b) an overlay protection plate for protecting against paving material entering said light fixture support during airport paving operations; (c) plate locating means for locating the position of the overlay protection plate after the airport paving operations have covered over the overlay protection plate. The plate locating means comprises i) a ferrous center point rod having a threaded bottom end connected to the overlay protection plate through a threaded center hole at about the plate center point and a threaded top end capable of being positioned to set a rod height of about one-half inch (1.3 centimeters) below the final pavement surface; (ii) a magnetic detecting device for locating the center point rod when buried in pavement. The plate withdrawal means removes the covered overlay protection plate, wherein the plate withdrawal means is capable of removing the pavement cover in substantially one piece over the overlay protection plate. The plate withdrawal means comprises (i) a threaded top end on the center point rod; and (ii) a threaded eyebolt or coupling for attachment to the threaded top end.
