Wireless Towing Lights That Can Be Used On A Trailer

Updated 03/11/2026 | Published 02/10/2026

Question:

Do you carry a magnetic wireless trailer light system for a flat 4-pin connector. This is for a small 4 x 8 flat camping trailer. If so, please send me links or SKUs or part numbers. Thank you.

Hi Dick!

We do have an option for you, but these kinds of things are listed under flat towing lights, which is why you weren't having luck finding them on our site. So with that said, check out the following option:

Optronics Wireless Magnetic LED Trailer Lights Battery Powered Stop/Turn/Tail Kit with Transmitter # OPT88UB

This has magnetic bases and is technically wireless. However, the lights are wired together and cannot be completely "separated". So you would end up needing to run the wire that connects the lights either over or under your trailer/cargo. To my knowledge, there aren't any fully wireless (like each light has its own transmitter) options available.

What kind of trailer is it? And out of curiosity, why not just run wires for lights? It would likely be less expensive.

Thank you for the answer. I might end up rewiring the trailer conventionally. It's just that I have to flip it over and do the necessary work to wire it. I have to wait for a while as we still have over 1' of snow on the ground so I can't flip it over.

@DickZ I hear that. We are finally warming up here in Missouri so we can go outside to do things again. If you want to make it easier to do in the future, you could run some 1/2" piping where the wires are being run. The wires would be protected and it does make it easier to replace when needed. They just pull right through. Just a thought. : ) Anyway, let me know if there is anything else I can help with when you get to it!

Thank you. The piping is a good idea. I’ll have to flip it over to see how I’ll be able to mount it. My trailer has two small lights on the side near the front. Will one of your wiring harness kits be able to hook up to these as well as the two main lights on the sides toward the rear?

@DickZ We don't have a specific kit for that, unfortunately. The best way to get wire to those is to tie the wires together that are going into the butt connector. So two in one end and one in the other end. There are other connectors that make that a little easier, but they are not as reliable or secure as a heat shrink butt connector. At least that I have seen.

Hi, Lazer. One last question I hope. I bought butt connectors (DW05744-5) for the wiring harness. My question is after I put the wires into the two ends, do I need to crimp the middle part of it before I heat shrink the ends of the connector? Thank you for your help.

@DickZ Once you crimp the ends, you should be perfectly fine. I have seen people crimp down the center as well, but I don't thinks it's really necessary. It wouldn't hurt anything if you did though.
