What I mean is The sub hatch the one where you get in and out from is red underwater at night in external view.

install the mod "Dark Interior" and you will not have a red hatch anymore

Dumb Question::

Why did they even need a red lighting on a sub anyway? I understand while surfaced, a red light in the conning tower, maybe. But why the rest of the sub?

Wouldn't it have been easier on everybody to have good lighting for battle conditions?

If you would climb out the hatch at night from a lit interior you would not see a thing until your eyes would have adjusted to the darkness.

The red light accustomes your eyes easier to darkness (pupils don't contract as much as with normal light)
(I have heard that in real life troops also read maps with a red light, but can't confirm this...)

Ooh! Ooh! I know sir! Ask me! I know!

The rod cells in your eyes (used for night vision) are most sensitive to blue and green light. These higher frequencies cause the night vision system to shut down to avoid being overloaded, and it takes a long time for them to return to full capacity if you look at white light.

I also read somewhere that it's for orientation - when most of the crew rarely see daylight, it provides a psychological way to keep track of the days passing by.

Besides, it's spookier (and therefore cooler) this way.
