I call bollocks.
Not least because, if they're that close, they'd be in the fuselage, and so could see you anyway. Besides: you'd expect that to be a reason to keep the lights on.

EDIT: OK, having read emvee's reply, there might be something to it... though it doesn't seem like all that compelling a reason to me. Why worry about shining a light through the window (and from what distance is anyone's guess) when the perspex is reflective, and when, if the lights still work, that'd be better? (If they don't work, there's no point turning them off before landing...)
