Willie Althammer found this little gem.
I offer this as info only for the modification inclined….
Reference F4U Corsair in Detail & Scale, part 1 (XF4U through F2G, copyright 1998), page 42…. All Corsairs thru -1A and early -1D’s (up to BuNo F4U-1D BuNo 57483 and FG-1D up to 87987) had a white teardrop shaped recognition light on top of the right wing only. Same fabric panel as blue formation light (just forward of aileron) and at the forward edge of that panel just as it ends before the metal leading edge.
Tamiya made no provision for it IIRC.
