WTB gaskets and bulbs for masthead?

josrulz · #1 04-16-2009

Hi all,
This is probably going to turn out to be a dumb question, but I'll try anyway. The mast is out on our boat, and I figured I'd replace the masthead light bulb (and pick up a spare) and gasket. Also looks like there's a rubber ring/gasket for the wind machine that's dead. I have pics below--any ideas on where to get what?

First, the bulb and cork gasket for the masthead light:

Second, the rubber ring for the wind machine mount:

I appreciate any help you can provide!

You should be able to get those rubber grommets at a lot of electronic supply houses...

The bulb should be pretty easily available too... but I'd recommend cleaning the contacts and using a good dielectric grease when putting the new bulb in...it'll help prevent corrosion.

Thanks sailingdog. Any idea how you get the bulb out? I tried the push and rotate method, but I think I'm supposed to release it--maybe with a screwdriver on the side? Not sure if you're familiar with this fixture or not (new to me).

Also, do you think Defender would have the parts and grease? Just asking because my boat's not far from there.
Thanks!

That looks like a standard bayonet bulb fixture... chances are that the bulb isn't rotating since it may be stuck because of corrosion. PBlaster might help free the bulb.

Defender probably does have the parts...but I'd check with an electronics shop or hardware store on the grommet, dielectric grease and bulb, since they might be a good deal less expensive... and the grommet, dielectric grease and bulb probably aren't "marine".

I am doing the 28 year old wire and light thing right now do you self a favor and start buying new fixtures and wire as you can afford them because i had nothing but grief with the old stuff between the voltage drop in the wire and the foggy lenses there was no way they putting out a safe amount of light

Sailingdog, so you think it is the push and rotate type? If it is, I don't mind working it some, just didn't want to try to force it do something it wasn't meant to do.

Tommays, I agree with your line of thinking--I'd like to replace all the lights, but the boat's 350 miles away, so I really just need to get her home first. She'll be in the water in a few days, so I need to replace any bulbs and get spares, and worry about anything else once she's conveniently located 10 minutes from my house (assuming all goes well).

dont mean to but in but dog is right thats a push and rotate 1/4 turn actually - just changed my masthead bulb,same setup. Luckily for me the PO had used dialectic grease (36 yr old boat) I have no idea how long the bulb had been in there.

Yup... Pretty sure it's a bayonet mount... just replaced one like that last season on a friend's boat.

For future reference, I do like the Aqua Signal Series 32 LED navigation lights.

I like the Orca Green Marine Tri-Anchor even better...

dont bother changing bulbs put in a led light. the standard wattage is 20 watts, or in 10 hours about 18 amp hours of battery gone. if you go led it will be closer to 1/2 amp an hour or 5 amp hours a night

sailingdog · #10 04-16-2009

Really don't recommend this, since it is likely that the LED bulb and fixture will not be USCG certified. Currently, the only replacement LED bulb/fixture combination that is USCG certified is the Dr. LED White PolarStar 40 and the AquaSignal Series 40 anchor light.

If you get hit and you're using non-certified fixtures... the chances of getting into trouble in a civil suit is very high.
