Adapt any Bi-Pin G4 LED bulb to a bayonet or screw-type Edison E26 / E27 or Mini E14 screw-type socket. Bayonets and screw types bulbs are common in older boats and RVs. Insert the adapter into your existing socket and convert to any bi-pin style G4 LED bulb.
Swiveling bayonets come in both standard types: BA15D (double contact base) and BA15S (single contact base).
E26 Edison - same screw base as used in household lamps.
12V or 24V use only.

Adapters work fantastically, so happy to finally get away from inefficient tungsten bulbs. My only advice is to make sure you have the space for the adapter + G4 LED bulb. If you're replacing a TS90 bulb (the short small bulb) you likely won't have room. I tried to use this adapter + micro G4 bulb-- even just adapter without LED was too big. All of my other bayonet applications worked great.
I was talking with a fellow offshore cruiser about wanting a Red/White fixture for over the chart table. I was holding out because I really liked the current fixture and also having all my fixtures match. He excitedly showed me the MarineBeam Red/White bulb that worked off a single on/off switch. Amazing! The only problem is I have old fixtures that use the older bayonet style bulb, not the newer 2 pin G4 bulb. Turns out not a problem at all, MarineBeam sells the adapters!
What a great solution. I was able to put Red/White in my 2 heads,, my cabin, the galley, over the dinette as well as over the chart table. I have been using them for a few months now and they are great. The only minor issue is they were crooked in the fixture, but my fancy glass diffuser on the fixtures made it not noticeable. I loved the solution so much when my cheaper Amazon LEDs started flickering I oredered some white only G4s from MarineBeam instead of using the spares I had on hand.
Upon ordering the next batch of bulbs, I noticed a YouTube video on the Bayonet G4 adapter. I wondered what is so special about the adapter to warrant a video? I had to watch it to find out and was very pleasantly surprised! The bayonet swivels to make sure the G4 bulb faces downwards! I went in and readjusted all my current installations and love them even more!
Easy install and much brighter that I expected. Works perfect for the archway lights
