Roadmaster Flat Tow Wiring Harness

  • Removable Tail Light Kit
  • Bypasses Vehicle Wiring
  • Magnetic Mount
  • Universal
  • Roadmaster
  • 20 Foot Long Harness

Avoid tapping into your towed vehicle's electrical system by using these self-contained tow lights. Heavy-duty magnets keep lights securely in place on your towed car.


Features:

  • Allows you to legally tow your car without having to tap into its wiring
  • Eliminates risk of electrical damage to towed car
  • Attaches securely with magnets
  • Connects directly to motor home wiring, bypassing towed vehicle completely
  • Has heavy-duty vinyl casing for superior protection of wiring
  • Meets Department of Transportation standards
  • Fits all vehicles
  • Includes 2 lights and wiring harness with 4-pole flat trailer connector
  • Length of wire:
    • Wire that connects the lights: 53-1/2"
    • Wire that extends out the back of the light: 243"
    • Wire with 4-pole connector: 35-1/2"
  • Limited Lifetime Warranty


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 void your manufacturer's warranty. Magnetic tow lights avoid this problem by having the wiring run underneath your car and plug into your power source.

These lights have worked flawlessly for the whole 2023 camping season on my RV towed vehicle. I mount them on the rear of the roof so they are nice and high above bicycles on a hitch mounted rack.



by:
Jeep

They were shipped fast and arrived quickly. These are quality lights with very strong magnets. I installed them on my Jeep in no time after making some steel brackets for the tubular aluminum bumper. Would be nice to have 5 or 6 magnetic clips to place along the wire to secure it to the vehicle. I highly recommend these lights.

Extremely happy with the tow bar wiring. Not one problem for the year!

Timely receipt. have not installed yet. but the instructions seem simple enough.

2005 Subaru Forester

I like these lights, nice strong magets hold them securely to car roof. I use them because my bikes in bags cover my tail lights. I added LED bulbs because when I tow the car with my RV these additional lights put to much load causing voltage drop and dim lights.

These lights are still working well only improvement I could suggest is if they could somehow maybe put up plastic layer between the magnets and the roof because they’re taking paint off, if they could still make the magnet is strong.

Jeep Wrangler

I purchased the Curt Tow Bar with Adjustable-Width Arms - Car Mount - 2" Ball - 5,000 lbs. initially I was Leary of the product because of its low price compared to other tow bars. I now can say my concerns were needless because after flat towing my Wrangler over 5,000 trouble-free miles I have nothing negative but only positives to report. The best thing I like about the tow At is that it only takes 5 minutes to attach and unhook.



by:

Fast delivery. Did a test as soon as I received the light kit. Flawless. Magnets very strong but safe for car finish.



by:
2010 Chevrolet Silverado

Everything was delivered on time and worked perfectly. This solved my concerns about towing my car with my RV with a car dolly.



by:

I did a mock-up set-up and this kit works as advertised.
Magnetic bases are strong, it should fit my needs perfectly.

Good light set. Works perfectly and has held up well.

Heavy duty magnets gave me the security of knowing they wouldn’t come off. Very easy to install!

easy hitch
is far better than I expected....very nice. I should have gotten this sooner!!!



by:

Very simple product. Exactly what I wanted. I need to do something more permanent but this worked for our trip. The most important thing was I needed it fast and I got it in time.
Friendly and informative people on the phone were knowledgeable and new their product. I will shop here again.

These are the products that we needed and you were able to provide them.



by:

Very strong magnets and plenty of length on the cord for a car in tow.

Thanks

I looked everywhere for these lights. Lots of cheep ones out there for 2-2X $$ but these are the real deal and a great price. Shipment was early and response was great. Thank you for the quality product.

    In regards to a 2021 Lincoln Corsair, only the PHEV models with 2.5L engine can be flat-towed.

  • Recommended Baseplate For A 2008 Mini 2-Door Hardtop
    Hey John, If you have a 2008 Mini Cooper hardtop S-model or 2008 Mini Clubman hardtop then you'll need the Roadmaster # 521877-1. This will work with Aerodynamic Package, but not with Sport suspension. If you have a 2008 Mini Cooper hardtop base model then you'll need the Roadmaster # 521878-1. This does not fit models with Aerodynamic Package or Sport suspension. If you haven't picked out the rest of your flat towing setup then I have the following recommendations for you: Tow Bar:...

  • Which Base Plates For Towing Will Fit A 2010 Jeep Wrangler Unlimited
    Both the Roadmaster EZ4 Base Plate Kit # RM-521448-4 and the Roadmaster EZ5 Base Plate Kit # RM-521448-5 will fit your 2010 Jeep Wrangler Unlimited if it does not have an aftermarket bumper, winch, or guards. I recommend the Roadmaster EZ4 Base Plate Kit # RM-521448-4. The Roadmaster EZ series base plates are our most popular base plates. They will fit all the Roadmaster tow bars and they have the hidden bracket design. The EZ5 series base plates will not work with tow bars that require...

    The RoadMaster Blackhawk 2 All Terrain Tow Bar # RM-422, is a bolt on application designed to bolt onto a vehicle that is equipped with Blue Ox base plates. But first, you would need the base plates. For base plates, you can use Roadmaster MX base plates, # 492-3. To install the base plates, trimming of spoiler, air dam, grille or plastic fascia may be required on some models of the 2004 Ford Heritage F-150. Base plate installation requires a good amount of mechanical experience and skill...

You mentioned that you have a tow bar and all of the accessories. I wouldn't be doing my job if I didn't make sure you had everything you are going to need. Flat towing requires 5 main components: base plates, tow bar, safety cables, lighting, and supplemental braking. We have the base plates and tow bar covered so if you need...

  • Tow Bar Wiring For 2021 GMC Sierra
    They do not; for tow bar wiring on your 2021 GMC Sierra 1500 you will need a splice in kit, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. If you do not want to splice your only other option are magnetic tow lights, the Roadmaster Standard Magnetic Tow Lights # RM-2120.

    To flat-tow your 1990 Mazda Miata MX-5 behind your 2001 Winnebago Brave, you will need base plates, tow bar, safety cables, vehicle wiring or lights, and a supplemental braking system. For a base plate kit, you will need Roadmaster XL Base Plate Kit, part # 711-4. The XL Base Plate Kit features removable draw bars, so when you are not towing your Miata, the base plate brackets are less visible. For a tow bar, I would recommend the Roadmaster Falcon 2 Tow Bar, part # RM-520. The Falcon...

  • Can Magnetic Light Kit # RM-2120 Wiring Be Attached Directly to the 7-Way Connector of a Tow Dolly
    You could potentially install the magnetic light kit # RM-2120 in the manner you have described. However, you would need to make sure the magnetic lights wiring is connected on the tow dolly side connector for easy installation and removal. Adding more wires to the 7-Way can increase the chances of a short circuit and there may not even be room depending on the gauge of wire used on the tow dolly. If there is no room or it looks like the wires for adjacent circuits could touch, I recommend...

The base plates provide an attachment point for the quick disconnect bracket on the Tow Bar. For the wiring, there are three different methods that can be used. The simplest way to go would be to use the magnetic mount light kit, part # RM-2120. This kit has the benefit of...

    Curt front mount hitch # C31063 will fit 2-wheel drive models of the 2008 Ford Ranger unless manufactured in a Canadian assembly plant. A front mount trailer hitch does not replace the need for base plates to flat tow a vehicle. Flat towing requires 2 attachment points on the vehicle, not a single one like a hitch would offer. For base plates, if you have a Sport model use # 477-1. For an XL or XLT 2-wheel drive, use # 477-5. For a compatible tow bar you can use any Roadmaster tow bar,...

While you could do some cutting and splicing to get it to work, the much easier option is to go with a magnetic light set with a 4-flat, the Roadmaster Standard Magnetic Tow Lights # RM-2120.

For base plates, you can use # 1541-1 if your CR-V does NOT have a brushguard. If it does have a brushguard use # 1541-3.

First, if you will not be towing the truck very often, I recommend using a magnetic light kit like # RM-2120. If you will be towing the truck frequently, I recommend a diode kit, # RM-154.

    The difference between the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 and Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 is how tow bars attach. As the name suggests, you will connect your tow bar straight to the direct-connect base plates while the crossbar style will require you use your tow bar's crossbar or quick-disconnect. This makes the direct-connect the easiest base plate to connect to and disconnect from. Because of that, for your 2018 Jeep JL Wrangler Unlimited...
