X2. True, the fixture you have has an on/off switch on the light, but.
If neither light is working, this may also be controlled by an on/off switch (or two)somewhere else in the camper. Look for rocker switches at your entry door down low, or at the main control panel where the A/C, water heater, etc. switches are located. The switch at the entry is to allow you to turn on an interior light when entering. This may also be a 3-way switch controlled at two points plus the light fixture. Reminder, if the fixture switch is in the off position, the light will not come on when the rocker switch is activated, so you have to flip the fixture switch when testing. If that doesn't work, you may have to remove the fixture and check for continuity.

As for the bulb, this is a T10 base light bulb. They can gently be rocked from side-to-side while firmly pulling out. As others suggest, it is a great idea to replace standard filament bulbs with LED bulbs such as the GRR T10 921. These come in a variety of brightness and from "daylight" to "soft" yellow hughes. The GRR series bulbs are shaped like a ping pong paddle and have a collar at the base of the LED disc. I use a kitchen spatula against the collar to seat the bulbs. I tried using the discs at first, but, they bend easily, but did not damage the bulb.

This, by a long shot, is not a dumb question. I have had considerable experience with electrical circuits and those in our unit had me baffled for spell. Changing out to LEDs is an excellent suggestion. They operate cooler, use minimal current, are brighter and will probably last for the life of the camper. The cost for changing out all of the fixtures to LEDs, including the bay lights, was $40 with a couple of spare bulbs if ever needed.

I too had to learn the trick, starting with getting the light cover off. Then, what part is the bulb and what part us the socket? Pull on the glass part while holding the plastic part steady with the other hand. Try switching bulbs with others in your camper you know are good. If the light come on you've got part of your questions answered. Take the burned out bulb to an automotive store (remember it is 12 volt like a car) for a matching replacement. They are cheap.
Now, if you want to go with LED bulbs, check on Amazon for the best prices. I just replaced all of ours this spring and thought there were some bad ones in my package until I read on this forum that LED bulbs have polarity and must be inserted correctly. That meant flipping about half of mine over when I reinstalled them. They work great now. Can't wait to go camping and actually use them.
Good luck

A problem with removing one of these bulbs is you have to jiggle it side to side to break it loose. Doing that will cause the socket to move at the attaching rivet and nothing happens. To prevent that grab the base part where the bulb slides in with some needle nose pliers while you jiggle the bulb.
