Fixing Interior Lights
There are a few reasons why your interior lights of your RV might not be working. These include damaged wires, issues with switches, and issues with power supply. Let’s take a closer look at each one of these below.
Burnt Out Bulbs
The first, and easiest thing to check, is the bulbs. If most of the lights are working, check the bulbs in the ones that are not. If they are burnt out, replace them with new ones. If they come on, then you’ve fixed your issue. If not, then you’ll want to move on to check for damaged wires within the socket itself.
Damaged Wires
If most of the lights of your RV are working properly, but a few of them are not, it could be due to damaged wires. At this point, you can be sure that it’s not the power supply that is the problem. The power supply is obviously doing it’s job.

If you suspect that it’s broken wires that are causing the issue, then recommended to contact a professional Auto Electrician to inspect and repair faulty equipment.
Check Switches
Another common reason for interior lights in your RV not working is defective switches. Depending on the type of lights installed in your RV, you need to make sure the switches are working properly.
If your interior light has buttons installed in the light frame, you’ll need to remove the cover and inspect the button. After some time, dirt begins to gather behind the button. Therefore, you need to take the time to clean it properly and check the bulb under the cover. If everything looks good, simply put the light cover back and that should fix the issue.
Check Power Supply
If you’ve checked the bulbs and switches and have not gotten results, chances are the power supply is the issue. This will be especially obvious if you’re having issues with all of your interior lights.

This can be confirmed by connecting your RV to shore power. If the interior lights work, you need to have your batteries checked.
In addition to the battery connection, you need to inspect the breaker connections and the fuse box. Recommended to contact a professional Auto Electrician to inspect and repair equipment issue.
Of course, the reason this is the last thing on the list is because replacing the battery is the most expensive option. You’ll want to rule out the other options first- but if you can’t resolve the issue of interior lights not working through those methods, replacing your batteries is your final option.
Conclusion
Before you head out in your RV for an excursion, you need to take the time to inspect it and make sure that everything is working properly, including your interior lights. If there are some issues, these tips should help you resolve the issue. Hopefully, replacing the bulbs will fix the issue- if not, you may end up having to escalate to having your RV batteries be replaced.
