Red light in submarines
Hi there.
No, the red light is not referring to the sort of district where one can purchase company for the evening
I'm referring to some parts in the movie Das Boot where the captain of the submarine gives the order for all normal lights to be turned off, and in its place a dark, red light comes on.
I was just wondering what the purpose of that was. Was it to conserve electricity? or some other reason?

And if you view a lighted object with night vision eq you will loose your night vision. when we used that in my time in the military we observed only by one eye even with night visionAndy H wrote:It takes the human eye a full 40 minutes on average to be fully orientated to night vision.
Soldiers, snipers especially (if no night vision equipment is available) are taught to keep one eye closed/covered when viewing lighted objects at night

Also "war lamp" is used today on some vehicles, i guess that it has to do with avoiding detection. If the vehicle has normal white light inside and the door is opened, the white light goes off and a blue one goes on.
Same might be somewhat true of submarines. It would be much more comfortable if only red light would escape the sail hatch when some officer or lookout goes out, but this would only concern one hatch.

Hi Guys
In our boats Red/White lights also indicated day/night. Got a little confusing for crew after a few days without surfacing. Sunrise and sunset was worked out correctly for our position and lights switched on and
at the right time. Mostly for practice and I suppose habit.
Luckily Watchofficers got to use the periscope so we normally had a good idea if it was Day or Night .
We also used some red goggles before surfacing, to keep time to aquire night vision to the minimum.

No among you was a submariner, but I was... Very simple. An open outlet amid black ocean is a marker beacon visible from enormous distances. Better avoid it.Eden Zhang wrote:Hi there....I was just wondering what the purpose of that was. Was it to conserve electricity? or some other reason?
