• Troubleshooting Burned Out LED Bulb in Gustafson RV Reading Light # 277-000334
• The Gustafson RV Reading Light - Satin Nickel - LED - 3.24 Watt # 277-000334 does not have removable LED bulbs. They are integrated into the light and to replace the burned out LED, you would need to replace the entire fixture, which for the price point, isn't bad at all.

• Troubleshooting a Right Turn/Brake Signal on a Pop-Up Camper Trailer
• It sounds like the problem is in the way the your right turn/brake light is grounded. You said that there is power to the fixture which would mean that either the fixture/bulb is faulty or the ground is bad. Try finding a grounding point that is closer to the fixture and attach it there. Any paint-free metal surface that is clean should work well, you might try taking some sandpaper to the area to really clean it up and allow for the best possible contact. It sounds like you already...

• Troubleshooting Passenger Side Running Light On Tail Light Not Working
• Thanks for the picture! Based on the color of the wiring used on the light your red wire should be the turn signal and brake light wire, the black wire should be the running light wire, and the white wire should be the ground. You can confirm this by using a circuit tester like # PTW2993 to test the wires while a friend turns on the running lights, and hits the brakes and turn signals. Now since wire nuts were used, it is possible that the connections are not secure as they can come...

• Troubleshooting Enclosed Trailer Dome Lights That Are Not Working
• If the dome lights are wired to the 7 way connector on the back your 2017 Ram 1500, then start by taking a circuit tester # PTW2979 to check if you have 12v at the 12v output wire on your truck's 7 way trailer connector (this is the pin in the 1 O'clock position). If you do not have 12v here, then look in the truck's fuse box and see if there is a blown fuse or a bad connection somewhere along the wire. Worst case scenario you could rewire that 12v circuit using 10 Gauge Primary Wire #...

• Troubleshooting the Gustafson RV Wall Sconce
• The Gustafson RV Wall Sconce, # 277-000255 is a 12V light fixture that uses a 912 or 921 bulb. Ensure you are using the correct bulb is my first thought past ensuring that voltage is not excessive or that you have a short in the connected wiring. Please check bulb types and use a multimeter to verify correct voltage and perform a continuity check. Replacement bulbs are 921 LED Bulbs - 360 Degree - Wedge Base - 600 Lumens - White - Qty 2 Item # ARC48FR.

• Can LED Dome Light Bulbs Be Replaced?
• If you have the LED RV Dome Light with Switch # 328-K-1020BLSM2, there is no bulb to replace and you would need to replace the entire light. LED lights are generally designed to last exponentially longer than a standard light bulb but in some instances these lights do not come with replaceable light bulbs and instead have diodes. If this is a fairly new light or camper, there may just be a wiring issue that you can resolve by removing the light fixture and checking the wires for secure...

• Troubleshooting Trailer Lights Not Working With Power Verified at 7-Way Connector On 2019 Ford F-150
• It sounds like you have a ground connection issue either on your trailer or the trailer connector for your 2019 Ford F-150. Since you have already verified you have power going to the terminals on your trailer connector a ground issue is the most likely solution. Do be sure to check your light bulbs and fixtures for any damage which may have damaged the lights. The simplest way to do this is using a Test Light # PTW2993 to test for power at the light fixture itself. If you determine you...

• Can The Gustafson 12V RV LED Pendant Light Be Taken Apart
• I went out to the warehouse to take a look at the Gustafson 12V RV LED Pendant Light w/ Light Shade # 277-000456 and tried to disassemble it but they glued the screws in place on it so I wasn't able to take it apart without damaging the light. Most likely the stem either threads into the housing and you can try to unscrew it or you'll have to unscrew the LED portion from the housing to access anything. Worst case scenario if you can't get it off you can just glue the screws into place to...

• Troubleshooting Individual Brake/Turn Signal Light Not Working On Command Triple Trailer Taillight
• It sounds to me like one of the wires pulled out of the connector for the Triple LED Trailer Tail Light # CE44VR. There are 2 red wires that control the brake lights and turn signals on the taillight. One for the top light and one for the bottom. The simplest fix if you can not access the wiring connectors would be to use a Quick Splice # SWC502905-1 to connect the loose wire to the other red wire. If neither wire is loose either there is a break in the wiring or the LED's in the top...

• Grounding Problem on RV Towed by 2004 GMC Sierra
• The fact that everything pretty much works fine until the headlights are switched on tells the story. What you are experiencing is the classic symptoms of an insufficient ground connection. When the headlights are switched on, the wiring system of the trailer is drawing full amperage, which is when a problem will manifest itself. Make sure that the ground connection on the RV is securely connected to clean metal on the trailer frame. You can find this connection by tracing the white...

• Troubleshooting LED Tail Lights Not Working on Trailer
• The first thing you should do is trace the wiring from your tail lights to ensure there are no crimped, damaged or broken wires that are causing interference with the circuit. If you do that and find the wires are fine then I do recommend using Load Resistors # DI34ZR as this should allow the harness to "recognize" the low power draw from the LED lights # TLL9RK you purchased from us (thank you!)

• Fix for Loud Squeaky RV Faucet
• The first thing to check is that the O-rings inside the valve might need lubrication. If you do a youtube search on 'squeaky RV faucet', you can see a video showing how to fix it. Secondly, it's possible that the faucet is just plain worn out. Unlike residential fixtures, RV fixtures are designed to be lightweight and are designed for occasional, not constant use so they'll be primarily constructed of plastic rather than metal. Because of that, RV fixtures just aren't typically going to...

• Junction Box to Allow Re-Wiring Camper Trailer Lights
• In your camper's 7-way wiring the tail light circuit is separate from the brake light circuit. Each is carried on different pins/wires in the 7-way. If you refer to the linked image you'll see the function-to-pin assignments for a trailer-side 7-way plug. What they have in common is their ground and this is what I suspect is the issue. Some lights will used a wired ground while others will use the lights mounting hardware to make the ground connection. If I correctly understand the testing...

• Troubleshooting An Antenna That Only Works When The Lights Are Off
• The Gustafson 12V RV LED Reading Light # 277-000494 should only pull around 0.25 amps so it's unlikely that you're dealing with a power draw issue, but it wouldn't hurt to check anyway. With a multimeter # PT89ZR test the power at the antenna with the lights off and on. If you're receiving less than 12 volts at the antenna when the lights are on but getting a full 12 volts when the lights are off then they're just drawing too much for the circuit to fully power the antenna. This could...

• Running Lights Dim When Brake is Applied
• Three possible culprits come immediately to mind. First, the trailer might possibly be wired incorrectly. Try swapping the running light and the turn/brake light wire on one of the fixtures, and see if this cures the problem. Another possibility is that the light bulbs might be not be installed correctly. Examine them and make sure they are properly installed. Finally, check the grounding point on the trailer, make sure this connection is secure, and not corroded. If the light fixtures...

• No Left Turn Signal on Light
• Thank you for your purchase directly from etrailer of your trailer light. If you have no left turn signal the first thing to do is make sure your ground good as that is the issue with the vast majority of trailer lighting problems. Then you will want to check your trailer connectors for corrosion, which can be green or white in color. A build-up of corrosion can interfere with the signals getting through the connectors so if it is present you are going to need to replace the trailer plug...

• Troubleshooting Running Lights on 2010 Palomino Sabre 5th Wheel Trailer
• There are several potential causes for the lighting malfunction on your trailer, ranging from bad bulbs in the specific fixtures to damaged wiring within the trailer frame to a weak ground wire connection. You can do some simple tests to determine where the issue may be. If you have a spare 12V battery you can try applying power directly from the battery to the problem lights' contacts. If they work when powered directly then you know the issue is somewhere upstream within the trailer...

• Trailer Right Tail Light Keeps Blowing on a 2005 Vintage Trailer
• The light blowing not once but twice indicates to me that there is a short circuit that is overloading the right side. First, you will need to isolate the short or this will just keep happening. Start with the vehicle side and trailer side connectors. You will need to make sure that they are clean and corrosion-free. Then make sure each is properly grounded to clean and corrosion free bare metal surfaces. Check the wiring leading back to the right side. You will be looking for any breaks...
