Demco Flat Tow Wiring Harness - DM36MV

  • Removable Tail Light Kit
  • Bypasses Vehicle Wiring
  • Demco
  • Universal
  • Wireless

Get turn signals and brake lights on your towed vehicle without tapping into the wiring. Light bar plugs into the 12-volt port in your car, with a wireless transmitter that plugs into your 7-way. Keeps you safe and legal while flat or dolly towing.


Features:

  • Displays turn and brake signals on your towed car without tapping into the wiring
    • Transmitter sends signals to the light bar wirelessly
    • No risk of electrical damage to your car
  • Works for both flat towing and dolly towing
  • Mounts to your vehicle's rear window with a strong suction cup
    • Light bar plugs into 12-volt port in your car
    • Transmitter plugs into RV's 7-way
  • Includes light bar, transmitter and receiver kit, and mounting kit
  • Made in the USA


Specs:

  • Universal fit for all vehicles
    • Requires 12-volt power port
  • Cord length: 11-1/2'
  • Light bar length: 17"


Note: If you have to disconnect your vehicle's battery to flat tow, use DM83FR (sold separately) to get power to your 12-volt port.


The law requires that all towed cars have functional signal and brake lights in sync with the RV towing them. Most wiring kits require you to splice into your vehicle's electrical system, but doing this can both be a hassle and void your manufacturer's warranty. This light bar, on the other hand, is a super convenient plug-and-play option, with no splicing involved. The bar itself plugs into the 12-volt port in your car, while the wireless transmitter plugs into your 7-way and sends the RV's brake and turn signals to the light bar.

doesn't work without an adapter for sprinters... otherwise fine...

All of the parts came well packaged and protected.

Easy to set up. No need to splice into your tow vehicle’s wiring. Works like a charm



by:

Shipped quick and worked when plugged into the 7 pin plug on the RV. Would be 5 stars, but I tried to test it with it plugged into the 7 pin on a 2022 GMC but it didn’t recognize it was there. I know that plug works from other trailers, but it did not like the wireless plug.

On the RV, works flawlessly and from further distances than the towed will be behind it. Much easier and nicer than splicing into the wiring on a newer vehicle.

  • Plug And Play Taillight Wiring Harness For Flat Towing A 2021 Ford F-150
    To avoid splicing into your 2021 Ford F-150's wiring I recommend the Demco Wireless LED Light Bar for Towed Vehicles # DM36MV. This will allow you to simply plug into your RV and suction cup/strap down the tow lights to your vehicle and go. I recommend using some Dielectric Grease for Electrical Connectors, 2 oz. Item # 11755 on the 4 pole connectors to prevent corrosion.

  • Towing Lights that Bypass the Tow Vehicle's Wiring and Are NOT Magnetic
    If you don't want to tap into your 2018 Jeep JL Wrangler's wiring to tow and your top does not have any metal for our magnetic lights, then we have one other option available for you, the Demco LED Light Bar for Towed Vehicles w/ Wireless Transmitter # DM36MV. This light bar uses suction cup to attach to the roof or trunk and has a secondary connection by straps. This may work for your soft top, but I would suggest finding something with a suction cup on your roof first to test how well...

  • Why Wouldn't Demco Wireless LED Tow Bar Lighting Kit DM36MV Work with Mercedes Sprinter
    German vehicles like the Mercedes Sprinters have trailer wiring that just does not like to work with LED lighting like what the Demco part # DM36MV provides. But thankfully we have an adapter that was designed to solve this problem with the Curt 7-Way Adapter part # C57003. The error code you are seeing is for a "bulb out" or basically the vehicle thinks you have a blown taillight.

  • Is The Demco LED Light Bar For Towed Vehcles DOT Approved And Legal For Use
    Hi Chris, Yes, the Demco LED Light Bar for Towed Vehicles w/ Wireless Transmitter # DM36MV is approved and legal for flat towing your vehicle. It's designed to attach to the rear window with a suction cup and face rearward so that others on the road can clearly see your light signals. There could be separate laws depending on the area you're traveling through so you'll need to check with those municipalities but you really shouldn't have an issue unless your rear window is dirty and not...

  • Can the Demco LED Light Bar Be Connected to a Splitter
    Hey Steve, so in regards to your first question I don't see anything wrong with using a splitter and an extension cord with the Demco LED Light Bar for Towed Vehicles w/ Wireless Transmitter # DM36MV as long as it's getting 12V, and your cords are protected, it doesn't matter. For your second question, there is not really a way to tell but since your Jeep does not have to have it's battery disconnected to flat tow, you shouldn't end up with a dead battery. If it turns out you need to...

  • What Flat-Tow Setup do You Recommend for My 2017 Ford F-250?
    I have a great solution for you. Since you say that you are looking to flat-tow multiple vehicles, I strongly recommend the Blue Ox Patriot Portable Braking System # BLU37TR. This system is a much more reliable and higher-quality system than a Brake Buddy system. Also, with the Patriot, you do not need any additional extra vehicle wiring to use it in another vehicle. You simply remove the Patriot from the F-250 into the other vehicle. For the F-250, you need the Roadmaster Brake-Lite Relay...
