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.

Video Transcript for Roadmaster Tow Bar Wiring - Bypasses Vehicle Wiring - RM-2120 Review

Today we're going to take a look at the Road Master Standard Magnetic Tow Lights. Now the law does require that all tow cars will have functional signal and brake lights in sync with the RV that's towing them, but most wiring kits will require to splice into your vehicle's electrical system, but doing this could void the manufacturer's warranty on the vehicle. Now these magnetic tow lights like these will avoid this problem by having the wiring run underneath your car and plug into your power source. There's no splicing required. This will basically allow you to legally tow your car without having to tap into it's wiring. It does eliminate the risk of any electrical damage to the towed car.

It does attach securely with these large polished magnets on the bottom here that hold the lights better than the competitors. It will connect directly to the motor home wiring, bypassing your tow vehicle completely. It does have a heavy duty vinyl casing for superior protection of the wiring, and this kit does meet the DOT or Department of Transportation standards. It does fit all vehicles. It includes the two lights and the wiring harness with the four pole flat trailer connector right here on it. It also comes with the four splice connectors that you'll use to attach to your RV's wiring, and a nice set of detailed instructions on how to install everything.

Now the length of wire on this, the wire that connects the lights, another words this wire here between lights is about 53 1/2 inches. This length of wire that extends out the back of the light is about 20 feet. It allows you to plug into the RV and run it to the back of the vehicle. Then the wire right here that's on the four pole connector harness is about 35 1/2 inches long. I just want to show you I got a piece of metal here but I'll show you how strong it is.

You can see it does attach very securely, and to get it off it does require some good strength to pull it off. They are a strong powerful magnet. That should do it for the review on the Road Master Standard Magnetic Tow Lights.

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. 715183

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. 414364


Comments

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.

Ask the Experts about this Roadmaster Tow Bar Wiring

Do you have a question about this Tow Bar Wiring?


  • Should 2005 Mini Cooper with Manual Transmission be in Gear or Neutral for Towing Behind Motorhome
  • According to page 137 of the owner's manual it looks like you can only use a tow dolly to tow your 2005 Mini Cooper if it has an automatic transmission. Since you have a manual transmission you need to flat tow it otherwise you will damage the transmission. The manual doesn't say anything about what gear to put your vehicle in but I would imagine it is neutral. You will want to confirm this with your local Mini dealer. For a complete flat towing setup you will need a base plate kit,...

I've provided you a diagram from the installation instructions that will show you exactly how the whole towbar/base plate connection comes together. If you're missing the quick disconnect portion, you can obtain a replacement using part # 910021-00. Keep in mind that the Falcon 2 towbar is only directly compatible with Roadmaster base plates.

  • To use the Roadmaster Even Brake Braking System, # RM-9400, in your 2011 HHR, you will simply install the braking system using the installation instructions that came with the Even Brake system. The only difference in the installation is that you will use the 2nd Vehicle Kit, # RM-98400, instead of the parts that were included with the Even Brake system. The first step to install this kit is to find a suitable location for the breakaway switch and the ICX transmitter. The breakaway switch...

  • Recommended Components Needed For Flat-Towing 2016 Ram 2500 4x4 Diesel
  • I called my contact at Roadmaster and there are no base plates designed to work with your StowMaster tow bar available. The weight capacity of the StowMaster is just too low to use with your truck. In order to flat-tow your Ram 2500, you would need the Roadmaster MS Base Plate Kit, part # RM-296-2. You would then need to upgrade your tow bar to the RoadMaster Blackhawk 2 All Terrain Tow Bar, part # RM-422. This tow bar will work with the base plates I mentioned and it has a 10,000-lb...

  • I confirmed with Blue Ox that the Blue Ox Base Plate Kit, # BX1633, will fit on your 2002 Chevrolet 2500 HD and it will support the weight of your truck. Our website separates the vehicle fits for base plates because there are some base plates that will not fit the HD models, but this base plate will fit. Before you attempt to flat tow your truck, I recommend checking your owners manual for any flat towing limitations or restrictions that GM may have for your truck. If you determine...

  • Flat Towing Wiring Harness Options for 2012 Fiat 500
  • There are two ways you could wire your Fiat 500 for flat towing. In scenario # 1, you could use a 4 diode kit like # RM-15247 which would use your tail lights as stop/turn/brake lamps. Your lights would work normally when actually driving the Fiat, but when you're flat towing, you'd only use the red bulb on the back of the Fiat for all the taillight functions. Scenario # 2, if you wanted the taillights on the Fiat to operate 'normally', that is to have the turn signals use the amber...

You'll also need two brackets for the lamps, part # BK70BB.

You should know that Honda states in their owner's manual that the Civic shouldn't be towed behind a motorhome.

  • Because the Chevrolet Avalanche vehicles have so much body trim that is plastic, like on the top of the rear bumper and the top of the bedsides, you would need to use the Standard Magnetic Tow Lights, # RM-2120, on the sides of the vehicle near the rear taillights.
