Is there a reason why only 4 out of the 6 lights are lit in the airlock room when it's depressurized?
The difference in color and light level, compared to how they look like (all 6 of them) when the airlock is pressurized seems to hint at that they may be in a lower power mode, so turning 2 of them off on top of that feels a bit unnecessary.
And if it is the reason, I think the pattern is not the best, since the middle and one of the side pairs are lit. If the two side pairs were lit instead, they'd better illuminate the equipment lockers along the sides of the room, or if only the center pair would be lit, it would save even more power and provide even lighting to the whole room.
(In case they are different, I noticed this at the South-West habitat location.)
