I need to replace incandescent bulbs in my cabin overhead lights. They are 12V and there is no markings on the bulbs I have looked at. Is this a T5 bulb? Picture shows it next to a 22mag round for size.

If it's larger than the standard 194 it may be a 906 or a 921.

If the contact wires are "bent around the glass base, they are 921's. You can buy LED replacement "multiple LED array" units that are cheaper than the actual incandescent bulbs and they use less energy.

Maybe just replace the fixture.

That looks like a 921 bulb. I replaced all of mine with 921 T10 LED bulbs. Much, much more efficient and cooler. Something like these -

They come in different levels of brightness so you would have to pick how bright, or not, you want them to be. They are a huge improvement over the type in your picture.

I am not interested in LED at this time; only need one bulb. Not interested in changing my fixtures. Just have one burnt out bulb. Haven't a clue what 194, 906 or 921 bulbs are. The size is similar in length to a 22mag round.

You have a 921 bulb. Most are now led type but here is a link to a package of 10. You may be able to buy a single one somewhere if you look around at an RV store, or even an auto store might have one.

The 194 bulb is typically what you find in the clearance lights on the outside and the "pancake" ceiling lights on the inside. The 921 is the same shape only larger and brighter.

Quick search shows Oreillys auto parts has 2 packs.

The photo I posted is available in the Auto Supply section at WalMart. They are also available at any hardware store, auto parts store and even at most Dollar General stores.

I live quite away from any of the stores mentioned so bought a 10 of them for under $10 on eBay (free ship). Thanks to all who answered. We don't use the cabin lights in our camper to the extent there is a lot of energy use and I suspect that buying the more expensive LED lights or even light fixtures wouldn't balance the books. This is the first of the 921 type lights I have had to replace in almost 3 years.
