Expert Answers about Kia Work Lights

• Trailer Running Lights Not Working Only When Starting Volvo XC90 Engine
• I honestly haven't heard of this type of issue before. Just to be clear, when you just have the light on in your Volvo the trailer lights work perfectly but when you actually start the vehicle the running lights stop working? If this is the case then the best thing I can recommend trying is testing the wires that are going to the black converter box on the Tekonsha T-One # 118411 with the vehicle running with a circuit tester like # PTW2992. Check to see if you are getting power on the...

• Troubleshooting Left Side Running Light Problem on a Boat Trailer after Installing a New Tail Light
• It sounds as if you either have a weak ground at the first light on the left side of the trailer that is not working or you have a broken or pinched wire on the left side after the light that is working. You have effectively eliminated the vehicle and trailer connectors by observing the fact that the first running light inline on the left side of the trailer is functioning properly and that all of the other trailer lighting is working. Start, by making sure the lights that are not working...

• Trailer Brake Lights Not Working, All Other Lights Work
• it sounds like you have a blown stop light or trailer brake light fuse. The tow package wiring on a vehicle is separate from the tail light wiring so it makes sense that the truck brake lights are working. Since you have isolated the issue as being on the truck side a blown fuse is the likely culprit.

• Snowmobile Tilt Trailer has Some Running Lights/Marker and Clearance Lights Not Working
• Running lights, side marker lights, and clearance lights all run off of the same circuit (the running light circuit). Since some of the lights are working that circuit is getting power so the issue must be with the lights themselves, a ground issue, or damage to the wiring. Since you have a tilt trailer it could be a weak ground issue. Running a jumper ground wire from the affected lights to the main trailer connector ground or axle will help. It will also help if the trailer is aluminum....

• What Do Each of the Lights on Adapter 7 Pole to 4 Pole with Tester and Cover # 47345 Indicate
• The test lights on the 7 to 4-Way Adapter # 47345 will illuminate when there is a signal showing that the circuits are working (on the vehicle side). The bottom one will light up when the running lights are working. The center light will illuminate when the left turn signal and brake lights are working. And the top light will illuminate when the right turn and brake lights are working.

• Troubleshooting Third Brake Light on Truck Camper Shell Not Working
• It sounds like you have tested the brake light circuit on the truck that you are connecting to for the third brake light. You also tested the light itself separately so you know it isn't simply a case of a bad bulb. If the circuit is good and the light is good but it isn't working only when the two are connected, it might be that the light is drawing too much power for the brake light circuit to handle. I recommend checking to see how much power the third brake light draws to ensure this...

• Troubleshooting Some Trailer Marker Lights Not Working While Others Work
• With you only having individual lights not working you will need to test the wiring and light bulbs at the lights themselves. You could have a damaged connection if the wiring off the main wiring which would be the reason only certain lights are working. You will need a Test Light # PTW2993 to check the wires going into the lamp are getting the power they need. You can also use it as a jumper to confirm the ground wire has a good connection. By connecting to the ground at the light you...

• Troubleshooting Clearance Lights on Trailer that Work but No Rear Running Lights
• The marker light circuit is the same as the running light circuit. So if you have clearance/marker lights that are working currently but the running lights of the taillights at the rear of your vehicle aren't currently working then that would indicate that the running light circuit of the trailer is somehow making it to your clearance lights but not to the rear taillights. This is most likely due to a cut wire so I would recommend checking the condition of the circuit from the clearance...

• Troubleshooting Trailer Lights Not Working Towing With Mazda CX-5
• There can be issues like this on some trailers using LED lights where they don't work at all. More than likely your LED lights aren't drawing enough power and this is the reason the tester works but not the lights on the actual trailer. This also varies between vehicles which would explain why it works on the truck and not your CX-5. In order to simulate more current draw, you can use load resistors like the # DI34ZR. You will need one per circuit so in this case 3 for the right turn/stop,...

• After Adding Side Marker Lights to Snowmobile Trailer, Some Work and Some Do Not Work
• Adding the additional lights might be overloading the trailer wiring on the vehicle side. Any given wiring set up is rated for a certain amount of amperage draw. If you try disconnecting the lights that do work and the other ones light up then you know this is probably the problem. There could also be an insufficient ground at the lights that are not working or at the main trailer connector since there is now more current running through the running light circuit. Since a test light ground...

• Troubleshooting Rear Running Lights on Re-Wired Utility Trailer
• In standard trailer wiring all clearance lights and running lights operate from the same circuit. This means that if some of the lights are working but a few do not, then those non-functioning lights may have a ground issue or other wiring problem isolated just to them. Different lights can use different ways of grounding. For example, if your side clearance lights that do work use a wired ground, but the rear lights use the light mounting studs or posts to make the ground then it is possible...

• One Running Light On Trailer is Not Working, All Other Lights Working Fine
• If just one running light is not working that indicates a ground problem. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. But they can show up any time. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The...

• Troubleshooting Left Side Trailer Running Lights Not Working
• If just the left side trailer running lights aren't working then the issue is almost certainly on the trailer side, as the running light circuit isn't side-specific on the tow vehicle end (if one side is working on the trailer you know you're getting appropriate power from the tow vehicle). So you can start at the trailer side connector and just visually inspect it for any corrosion or debris that might be built up inside the pins, cleaning out if needed. It could be something as simple...

• Trailer Left Side Running Lights Not Working All Other Lights Work
• On many trailers the running light wires are jumped from one side to the other on the trailer. This is because there is a single running light wire only ran on one side. A wire would have to be spliced in on the one side, ran to the other side of the trailer, and connected to the running lights. If using a junction box, the one running light wire from the trailer connector can go to a single terminal and from there you can run separate wires for the running lights on each side of the trailer....

• Troubleshooting Brake Lights Not Working on Tow Vehicle
• Sounds like you have a blown third brake light fuse on your tow vehicle if you can get all of the other functions to work but not the brake lights. Check out the fuse box of the vehicle and replace that fuse and you should see the lights work like they should.

• Select Clearance Lights and Marker Lights Are Not Working
• The marker lights and clearance lights on your trailer should all be tied into the same circuit with a jumper wire ran to each of them. Therefore, if there are some working but some that are not then this leads me to believe that there is either a short in the running light wire or burnt out bulbs. The bulbs are easy to check, just pry off the cover and inspect the filament. If you need any replacement bulbs let me know the number on the base and I will see if we have any options. If the...

• Troubleshooting Trailer LEDs that Don't Work that Are Replacing Incandescent Bulbs
• If you tested the LEDs and they work when they have power and ground the problem has to be the wiring of the trailer. Since previous lights worked there it would seem that the problem may be somehow ground related. Some assemblies ground through their hardware and other ground through a wire. I attached a couple help articles that might be informative as well.

• Trailer Clearance Lights Show Power but Some Will Not Light Up
• It is possible that the clearance lights are not working if you have a lot of clearance lights. This can overload the trailer wiring on the vehicle side and cause some of the lights not to work. You can check the amperage draw per clearance light by testing one at a time using a multimeter such as # PT89ZR. Switching everything over to LEDs will be much better because they draw only a fraction of the power compared to incandescents. Another possibility is a poor ground connection. All...

• Trailer Flasher Lights Do Not Work When Running Lights Are On
• It does sound like a classic ground issue you are having on the trailer since the flashers do not work when the running lights are on but work when they are off. The running lights have a bigger draw on the wiring and if the ground is not sufficient the other lights will not operate properly. I recommend to make sure all of the grounds on your vehicle trailer connector and your trailer are properly grounded to a clean bare metal surface. Running a ground jumper wire from each light to...
