I am in September 1939, patrolling off the Norwegian coast (AF87) and I encountered a Norwegian coastal tanker with no lights
![Hmmm](images/smilies/39.gif)
.From the first time i guessed it was an allied ship (not neutral) and i was prepared to attack it

but I confirmed its flag at a range of 900m
![gah! RT again!](images/smilies/bangrt2.gif)
.Is it possible for a neutral ship to travel without lights?
