    Does anyone know what bulb goes in the 1980-1990 vintage navigation / all around light with the round circular base? Would like to have to climb up onto the hardtop only once to replace the forward bulb (preferably with an LED).

    Thanks - Greg

    No Guarantee the socket isn’t damaged or hasn’t been changed... you really better off climbing up and pulling the bulb

    At my age I'll gamble on the cost of a bulb and hope for getting by with one trip.

    Come on Greg. I'm almost 71, just finished staining 2 decks, taking down half a tree and mowing 2 acres. Seriously speaking though you should have someone on board who can do these things. God forbid you're running at night sometime and it needs to be changed. Waiting to do it when you get to shore could get you killed when another boat can't tell what direction you're traveling. I hear kids are good for this sort of thing. Maybe you can borrow one if you don't have one of your own. Have you checked your spares drawer? Hopefully you have some there. If not 2 trips up still beats potentially 2 trips up plus 2 trip to the store.

    This is funny and not meant to be dis-respectful;
    With this idea and not knowing the mfg of the socket, plan on at least $225 of lamps in your pocket when you climb up for a one visit repair.
    There are just to many bayonet designs that go up there.
    AND, please consider a LED replacement that will help you not to go back up there anytime soon.
    Pull the bulb and then go shopping.
    Please be careful. We want to hear back from you.

    From the lens shape and since it's the same generation as my Viking with a similar layout lens, it is most likely a Perko. I found a marine light models bulb table which shows that model/style Perko as 31mm festoon, so I have a 31mm LED on it's way. If my guessing is correct I should be able to get it in one pass. If not I've wasted $10 for a bulb and will find out what I should have bought when I do go up.

    Bring a small stainless steel brush, contact cleaner and a couple of shop towels. Also a needle nose pliers. Leave the light switch on too. I think we should bet a bottle of rum on the number of trips up with no helper. What do you guy's think? 1,2,3,4 or 5 trips up.

    I can get my wife to turn the switch on and off for me, but not to climb on the top. My daughter is in NY so a little far to come help.

    It’s a good quality led? Just asking because typically nothing in the led world that is true marine quality that will last more than a season is $10... hopefully it’s not a “bestsuperextraled” type brand.

    (and this is coming from the guy with the $20 Rubbermaid steps.. but sometimes there are areas where you just shouldn’t ever skimp.)

    LED bulbs are hot or miss. I ve had some of cheap ones fail quickly and others from Amazon that lasted for years.

    Not only are LED hit and miss, the fixture requires a very specific bulb and wattage for visibility per regulation for the size of the boat. Need to match or exceed wattage/lumen. That's a tricky conversion to LED. Wouldn't want a clever insurance adjuster to pin the blame on your bulb and deny your coverage...just sayin'. Don't mess with the ability for others to see you at night and for the insurance to actually, you know, insure.

    In the end I ran this gauntlet, weighed it out, made the change to modern fixtures.

    Yes for nav lights I use marine LEDs bulbs certified for that purpose. I prefer LED bulbs to LED fixtures as the bulbs can be replaced in minutes. Over the last few years I ve had two LED nav fixture fail forgot the brand, perko and hella maybe.

    Guessed right on bulb size but fixture heavily corroded. Aft bulb works, but fwd doesn't. Surprised given condition that the aft one works. Will replace the fixture and make a second trip up on the top.
