Name for light?

[Sue and Henry]

This bulb is about 1 1/2 inches long and came out of the exterior rear light that helps you see the jack on the casita. There are no markings on it at all. I've never seen anything like it (it may be an extraterrestrial bulb from Mars). Does anyone know what it is called and where I can get another?

It's an automotive LED bulb

No idea what your bulb number is, but here is a similar bulb

I'd clean contacts before replacing the bulb. LED bulbs last a long, long time.

It is an "aftermarket" LED light made to fit into a standard bayonet base socket. Often used as a replacement for the old filament bulbs.

It looks like the LED lamps I have in my Casita
It's a rather common lamp .
Check LED trailer lights out of Washington State
Cost about $13
I've had them in both my Scamp and Casita , never had one failure.

That's the same style of LED bulb I put in my Amerigo, bought 10 of them for right @ $10.00 off of ebay. They are a replacement for the 1156 automotive and are polarity sensitive, if it has never worked for you try switching the + and - wires to the lamp.
I would test it with a couple of test leads & a battery first.

You guys are all awesome. Thank you for making the electricity in my life so easy! Sue

If this LED came from the fixture over the propane tanks on the front of a Casita, it is probably still good. With the cover off the fixture, spray a little WD-40 on the switch and operate it a few times. That switch apparently gets water in it and doesn't swap sometimes. You can also pull a bulb or LED out of another light in the camper and see if it works there.

I have 2 or 3 of those sitting in my drawer.

LEDs often only work one way in the socket. If yours has 2 contacts on the bottom, you may have to flip it over and reinsert it.

I find this stuff solves most of my electrical issues.
Leaves no residue, unlike WD40, and it doesn't stink.
