This is the type bulb I have in all the fixtures in the trailer. Some have one, some have two.

They are in the cheap oval flush mount fixture with the pop off cover. Can't locate them on the web.
I've replace two of them with this style LED fixtures.

And now I've lost the link to the bulbs you found.
