So a friend of mine asked me this today and I didn't have a good answer.. I'm sure one day I will.

Why do submarines use red lights?

I understand surface ships use it for better night vision, and because it makes it much harder for enemy ships to spot the lights in the ship...

But submarines do not have windows. The light wouldn't really be escaping the sub..
