So, if I understand you correctly:
The Nav-lights consist of:
1 fwd, 1 aft wing tip in fixed white (for redundancy)
(or did you mean that each "light" has two bulbs?)
So say the port wing tip to down view:
W---------------
R-
-
w
-
-
w
s--------------------
W = A White Strobe, R = Red Position Light
w = A white fixed nav light
s = stab logo light illuminating the stab
Are the strobes co-located with the red/green pos lights red & green? or just white strobes too?
Thanks for your input.
