Steve is right, illuminated ship is a feature of GWX.

This is a passage from GWX Manual:

Illuminated Ships

Historical background
Germany discussed treating well-lighted merchant ships as neutrals during its World War I unrestricted submarine warfare campaign, as belligerent merchant ships turned their lights off to avoid giving away their location, but this was only an informal convention. Neutral ships usually used red, green, and white navigation lights to reduce the danger of collisions at sea, but the masters of neutral merchant ships sailing alone during World War II would sail darkened if they felt U-boats would attack anyways.

Illuminated ships in GWX
Illuminated ships in GWX represent some (but not all) shipping of currently neutral countries; merchant ships from countries currently at war or allied with Germany will always sail under blackout conditions, while Red Cross hospital ships always sail under illumination. Note: Illuminated ships of neutral that leave port before their nations join the war are legitimate targets once war begins, but will remain lit until they reach port.
