RV lights not working when plugged in can be an incredibly frustrating problem. Often, RV owners have no idea what’s wrong or how to fix the issue, leading to long hours spent trying to troubleshoot. In this article we’ll provide you with some helpful tips and advice on what to do if your RV lights don’t work when plugged in.
How Do RV Ceiling Lights Work?
Before we discuss what to do when your RV lights don’t work, it’s important to understand how they work. RV ceiling lights are typically powered by a 12-volt DC power source.
Why Do You Have to Plug In RV Ceiling Lights?
Most RVs are designed to use 12V DC (direct current) lighting fixtures, which means they require a power source from the RV’s battery system. Installing light fixtures that work on mains AC (alternating current) is not practical for most RVs due to the limited space and weight limitation of the vehicle. Thus, RV ceilings lights are typically connected to the 12V DC power source via a plug and socket system.
When plugged in, the RV’s batteries supply power for indoor lighting needs as well as other electrical accessories like fans and TVs. The light fixtures also draw power from the battery when they’re switched off; this is known as “phantom load”. To reduce the amount of power being consumed when not in use, it’s important to turn off the light fixtures before unplugging them. 
Problem: The Gfi Is Tripped.
If the lights in your RV aren’t working when plugged in, it could be because the GFI (ground fault interrupter) has been tripped. This is a device that senses an imbalance of electricity passing through two wires, which usually occurs when there’s a short circuit. It automatically “trips” and breaks the circuit, preventing potentially dangerous electrical shocks. 
Solution: Reset It Or Call An Electrician To Do It.
If your RV lights are not working when plugged in, the first thing to do is reset it. You can usually do this by switching off the breaker and turning it on again after a few seconds. If resetting doesn’t work, then you should call an electrician to take a look at the wiring. An electrician will be able to diagnose the root of your problem and repair it accordingly.
If you’re not sure how to reset a breaker, refer to your RV’s user manual or contact the manufacturer for guidance. It’s always better to be safe than sorry when it comes to electricity and wiring, so calling a professional is often the best option. 
Problem: The Gfi Still Doesn’t Work.
If your GFI (ground fault interrupt) circuit isn’t working, it may be malfunctioning. Check to see if the reset button is popped out and if so, press it firmly until you hear a click. If this does not solve the problem, then you’ll need to replace the GFI outlet entirely. It’s important to have a qualified electrician do this, since the wiring for a GFI must be done carefully. Additionally, you may need to install a new circuit breaker if the current one is not functioning correctly. 
Solution: Get A New One.
If the GFI and circuit breaker are both functioning correctly, but the RV lights still aren’t working when plugged in, you may need to get a new one. Make sure to get one that is rated for use as an RV light and compatible with your specific RV model. You should also make sure that it has enough wattage to provide the appropriate level of light in your RV. Finally, you should make sure that the new RV light is properly wired and connected to its power source before using it. 
Problem: The Circuit Breaker Is Tripped.
If the circuit breaker is tripped, it’s likely that your RV lights won’t work. In this case, you’ll need to locate the circuit breaker and reset it. 
Solution: Reset The Breaker And Discover The Cause Of The Trip.
If the circuit breaker is tripped, you’ll want to take a few steps before resetting it. First, turn off all devices and appliances in the RV that are connected to the same circuit so that they don’t cause any additional overloads when you turn them back on. Then, check your wiring to make sure that nothing is shorting out. If necessary, replace any damaged wires and inspect all connections to make sure they are secure.
Once you’ve determined that there is no wiring fault, reset the circuit breaker by turning it off and then back on. You may want to switch it off for a few seconds before switching it back on just to be sure that everything. 
Problem: Your Ceiling Light Ballast Is Faulty.
If your RV lights are not working when plugged in, the issue may be a faulty ballast. The ballast is what regulates the electrical current for lighting fixtures and ensures that it does not exceed safe levels. If you have checked all of the connections and replaced any burned-out bulbs to no avail, this might be the problem. 
Solution: Replace The Ballast.
The most likely solution for RV lights not working when plugged in is to replace the ballast.
If your RV contains multiple lighting fixtures, check each one and determine which has a faulty ballast. Disconnect the power to that fixture before attempting any repair. Consult your owner’s manual or contact an electrician to properly replace the ballast with a compatible one for your specific model of RV. 
Problem: It’s Actually The Ceiling Light Fixture Itself That Has Gone Bad.
Sometimes, it’s not the wiring or plugging of your RV lights that is causing them to not work when plugged in. It could actually be the ceiling light fixture itself that has gone bad. To check if this is the case, you can carefully unscrew the light fixture and take a closer look inside. If you see any corrosion, electrical malfunctioning, or other signs of damage, then it’s likely that the fixture needs to be replaced. 
Solution: Check The Battery If Yours Has One. Otherwise, Repair Or Replace The Fixture.
If your RV lights still aren’t working after checking the wiring, it might be time to take a closer look at the battery, if your system has one. Check for any signs of corrosion or damage and make sure all connections are secure before proceeding with other troubleshooting steps. If that doesn’t do the trick, you may need to repair or replace the light fixture itself.
If repairing or replacing the fixture is necessary, it’s important to properly identify and remove damaged parts as needed. If you’re unfamiliar with this process, consider reaching out to an experienced electrician for a professional opinion. Be sure to check your RV manual for recommendations on any additional maintenance or repair work that might be needed. 
Problem: The Wiring Is In Terrible Shape.
If your RV lights are not working, it could be due to a number of issues. One potential issue is that the wiring of your RV is in terrible shape and needs to be replaced. This can be difficult because it requires you to access areas of your vehicle that may have been neglected for some time. 
Solution: Call An Electrician For New Wiring.
If it is determined that your RV lights aren’t working due to faulty wiring, then you should call an electrician. An experienced electrician will be able to inspect the wiring in your RV and replace any damaged or worn out wires. This is especially important if you’ve recently changed out fixtures or switches in your RV, as it may have caused the wiring to become damaged. If you’re not comfortable trying to repair or replace your RV’s wiring yourself, then calling an electrician is the safest course of action. Once the new wires are installed, your RV lights should work properly again. 
Problem: The On/Off Switch Works Sporadically, If At All.
If the on/off switch for your RV’s lights works sporadically, or not at all, it could be caused by a bad connection in the wiring. To fix this issue, make sure to check the wire connections and replace any corroded wire connectors. Additionally, if your on/off switch is flickering when you turn it on and off, it could be a sign of a faulty switch or wiring. You should have an electrician check the wiring to verify that everything is in good working order. 
Solution: Check The Switch And Consider Getting An Electrician To Install A New One.
If you have checked the circuit breaker and all lights are still not working, then you may need to check the switch. A faulty switch can prevent power from getting to the RV’s lighting system. If this is the case, then it is best to contact an electrician for help in replacing or repairing the switch.
It could also be a wiring issue, and having an electrician take a look at the RV’s lighting system will ensure that everything is properly connected. They may also suggest installing a new switch or replacing any parts that are not working correctly.
