Installed the four platenuts on the wing ribs. These will attach the landing light assembly to the wing. Located and drilled mounting holes in the mounting plate for the HID power ballast. Machine countersunk the platenut holes for the lightbulb ring attach points. Sanded and cleaned the mounting plate, then painted it with high-temperature gray enamel. Taped the Plexiglas light cover in place on the wing, marked it for trimming, then applied blue painter's tape to both sides so it won't get scratched when I cut it on the bandsaw.
