Submarines only use very few lights:
1. Bow and Stern (rudder) lights - the Bow light is contained withing the jackstaff, and is only used in port while moored or anchored. The Rudder light is used while underway surfaced, along with the Port/Starboard lights.l
2. Port and Starboard Navigation lights - like all vessels, submarines use Port (Red) and Starboard (Green) navigation lights, which are located on the submarine's sail/fairwater.
3. Yellow Flashing Light - Submarines traveling on the surface at night use a raised mast with a flashing yellow beacon. The beacon, along with the other navigation lights, tell other ships that the vessel is a submarine, and which direction it's headed.
4. Security lights - Mounted on the sail in port, they are used as safety/security lights while moored or anchored.
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
Fog Lights only, Low Beam only or Fog Lights + Low Beams.
It sounds as if you are looking for submarines.
submarines and bats both use sonar. Calvin was here
No - most modern submarines, depending on type, have between 15 and 25 torpedoes aboard.

oceanographers use submarines to take pictures of sea life and things that have been found or things that they are looking for.
The marines do not use submarines. Only the Navy does.
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
Type A midget submarines. (It's a funny name but that's what they're called.)
