my 1981 33 has Aqua Signal bow and stern lights, but I can't decipher the model numbers; were these "standard issue" on the Cherubini Hunters? if so, what are the model numbers? I plan to replace the bulbs with LEDs. . . also, the steaming light on my mast is a Perko with what appears to be a 10 watt festoon bulb; would it make sense to replace the bulb with an LED, or replace the whole fixture? are steaming lights subject to the 2 nautical mile rule? last, but not least, I plan to replace the masthead light - I saw one made by Sea Dog on sale for $32, it states it complies with USCG regulations, anyone see problems with this?
