Ok.. Y'all got your lights all screwed up folks.. "Formation Lights", "Position Lights", "IFF Lights" and "Navigation Lights" are not the same thing, and are not to be used interchangably...
The wing-tip and tail lights are: Navigation Lights and are Port-Red, Starboard-Green, and Rear, White.
On the De Havilland Mosquito Recognition Lights (Sometimes called "Position Lights", and "IFF Lights" are, from nose to tail, White, Amber, and Red, with round, flat lenses, and located on the lower rear fueslage center-line...
Some aircraft have as few as one Recognition light (The Spitfire had a white one located in a teardrop fairing just behind the cockpit on to of the fuselage), some are bloody Christmas Trees..
One such "tree" is the TBF/TBM which has as follows:
'Supplement to Grumman TBF/ TBM "Avenger"
1. Left Wingtip Navigation Light (red) - port wing tip.
2. Tail Navigation Light (white) - trailing edge of rudder, above trim tab.
3. Right Wingtip Navigation Light (green) - starboard wing tip.
4. Recognition light (green) - aft of bomb bay, centre fueslage line, ahead of amber.
5. Recognition light (red) - aft of bomb bay, centre fueslage line, ahead of green.
6. Recognition light (amber) - aft of bomb bay, centre fueslage line, immediately ahead of ventral gun position.
7. Formation (or Recognition) Lights (blue) - port and starboard wings, near the tips, in line with outside edge of ailerons.
8. Approach Recognition Lights (green, amber, red) - inboard leading edge of folding part of port wing.
9. Section Light (blue) - along aircraft spine, before, and almost touching tail fillet.
Another was the B-25... Lights all over it..
