What are the rules for navigation lights on a boat?

WAY TOO many vessels to list. Depending on where you are located, will depend on your guidelines, except for International rules. For International Rules you can refer to a book that covers "The Convention on the International Regulations for preventing Collisions at Sea, 1972" which is referred to as "72 COLREGS". If you are in the US there is a slightly different set of rules of "Inland Waters".
