Question:

Im looking for Wireless Magnetic Trailer Lights to use in case of emergency. On a recent trip...I had to leave after the sun came up because my clearance lights had a short that I could not find. My question is...is there some sort of temporary/emergency clearance lights I can buy along with the Wireless Magnetic LED Trailer Lights

Hey Mark, thanks for reaching out. We do have wireless taillights, but no clearance lights. I do have a few options for you to look at.

First, we have the Universal Magnetic Tow Lights # C6304. These use a wireless transmitter that plugs into the vehicles 4-flat plug, then the lights themselves are battery powered. They are technically wireless although you do have wires on the transmitter, and wires connecting the tow lights together.

If you want something that is more truly wireless, take a look at the Wireless LED Tow Light Bar # LIW-LDTL-7B. This has a transmitter that plugs into the vehicles 7-way, then the light bar itself has a rechargeable battery. The cord plugs into a 12v cigarette lighter outlet so it would be easy to keep it in your vehicle and keep it charged in case of an emergency.

Both of these are more geared towards a towed vehicle, but they can be used on trailer as well as long as you have a good steel mounting location.

Do you think either of these would work for you?

What kind of trailer do you have?

17 foot enclosed trailer...Covered Wagon CW7X16TA2 ...both will work...I think the one with the two separate lights will be sufficient. I also need to chase down the short....can you help with that too? What's available to test the trailer lights? Don't want to have to have my truck hooked up to the trailer the whole time.

@MarkC Tracking down a short in an enclosed trailer really comes down to isolating the circuit and working your way through it step by step. Start at the 7-way and check each function individually, then move into the junction box if you have one and make sure all your connections are clean and tight. From there, unplug or disconnect sections of the trailer one at a time, like the running lights, left/right turn, etc., and see when the problem goes away. That’s the quickest way to narrow it down without chasing the entire harness at once. Once you’ve got it isolated, you’re usually looking for something simple like a pinched wire, rubbed-through insulation on the frame, or a bad light housing letting moisture in. Enclosed trailers are especially prone to issues where the wiring runs along sharp edges or through holes without grommets. Take your time following the wire path, flex it a bit, and look for spots where it could be grounding out. Nine times out of ten, it’s something physical you can see once you’re in the right area.

Is the Tekonsha trailer wiring circuit tester worth it? I already know i have a short. I know it's the running / marker lights. Will it tell me anything else? Do you have a less expensive model?

@MarkC Its definitely worth it if you are trying to narrow down the source of a wiring issue, or if you like work at a shop and do a lot of trailer wiring repair. If you already know you have a short, and already know which circuit it's on, I can see how the Tekonsha Trailer Wiring Circuit Tester # 8010 might not be worth investing in. We do sell less expansive testers but they are all simple plug-in testers or wire probes like part # F4CT or # PTW2993.
