The red lights were used also for the crews quarters. Remember unless you're at battle stations all berthing compartments were red to allow off duty sailors some sleep. The other compartments were lighted by time of day. If you're not part of the topside watch, i.e. lookouts and officer of the deck,you never get to see outside. The only way to tell if it was day or night was to check the lights and see what color they were. Being in a darkened submarine, and surfacing into daylight never had a profound effect on your eye adjustment, you would have to have ripped them off once you got topside because it would effect your ability to see long range....
