As it says in the title.
The Physical switches within the cockpit in regards to external lighting do not appear to work correctly. The Fuselage Dim/Bright switch controls the tail light and the Wing/Tail light controls the Fuselage lights. It is impossible to change the lights on the wingtips without turning all external lights off. Anti collision lights seem to work as intended in that it does change blinks and can be turned off properly. Formation light brightness has no functionality and there are no formation lights. (This might not be implemented yet). When setting the aircraft to formation lights instead the wings blink white along with the anti-collision lights. When set to A-C, and all other lights off, the formation knob will adjust color strength on the wingtips.
I honestly can't imagine that this is how the lights work on the actual F-16, there's no internal consistently at all.
