Navigation Lights Quiz

This quiz will help you study your ship navigation lights.

This is version 1, and does not record your score.

You will be presented with a randow ship light pattern, seen from either the bow, port or starboard (currently I need to make a change before I can show the stern view).

You will then be given 6 possible choices. If you answer incorrectly it will show you the correct description of the pattern chosen, plus show you the correct answer for the pattern shown.
