Submarines have 5 primary navigation lights, though not all are used on the surface while in open ocean. The 3 primary lights are the Rudder (white light), Port (Red) and Starboard (Green). Additionally, a flashing yellow light is set atop one of the primary masts - this is a known warning to other vessels that the vessel is a Submarine.
The yellow light is used because at night, submarines are nearly impossible to spot; it's even difficult to maintain good orientation if you're topside and on deck at night while underway. Submarines also are much lower in the water than a traditional ship. Since a submarine's hull above the water only represents a fraction of its true size, knowing the vessel is a submarine lets approaching vessels know to steer further clear of the submarine because it is much bigger than is seen. The other lights are traditional.
In port or at anchor offshore, a Bow light on the Bow mast is lit at night - it isn't used while underway.

What type of lights do submarines use?
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.
