If that's a running light, keep in mind that in space, there's no atmosphere to refract or reflect the light back into those windows; if a direct line of sight can't be made between the light source and the window opening or frame, it shouldn't show up to the occupants.
Wouldn't those windows cut into the roof - which are beautiful - mean the running light was constantly irritatingly bleeding into the briefing room ?
And, hey, the windows may be polarized to block it, anyway .
I thought there was, just a line of sight as it's quite an erect
little niblet of a running light...
but I like the poloarsation explanation
