I have a 2005 16' cruiser, purchased new in september, with a perko red/green deckmounted navigation light. It quit functioning within a month after we bought the boat. The wiring and switch all seem to be hot which leads me to suspect the bulb. The light is a Perko 1167. It has a black plastic base, secured to the deck with two small screws. I have taken the screws out but the wiring is so tight I can't get the fixture raised enough to look under it to see how to access the bulb. Anyone have any ideas? I have sent several e-mails to the dealer on other subjects and on this subject and they have not responded, neither has the factory responded to previous e-mails so I am counting on someone here to steer me in the right direction. I don't want to unscrew several feet of wiring to get free-play in this fixture unless I absolutely have to. Hope someone has been there before me.
