2004 Acura TL - Roadmaster Standard Magnetic Tow Lights

  • Removable Tail Light Kit
  • Bypasses Vehicle Wiring
  • Universal
  • Magnetic Mount
  • Roadmaster

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


  • 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.

Roadmaster Standard Magnetic Tow Lights - RM-2120

Average Customer Rating:  4.8 out of 5 stars   (26 Customer Reviews)

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.


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


Works as intended. No issues.

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.

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.


Have not hooked up yet. But ordering and delivery are great


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.


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


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.

2011 Mazda MX-5 Miata

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


Works great!!


lights look fine....

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


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


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

Everything delivered even faster than expected - Thank you.

  • Lighting Solution for Flat Towing a 2010 Volkswagen Passat Behind a Motor Home
    Your assumptions are correct, the Tekonsha wiring harness, # 118562, is designed for it you were to need to power trailer lights while towing with the 2010 Volkswagen Passat. It cannot be used to power the vehicle lights while it is being towed. What you can use is a magnetic kit like # RM-2120. This light kit will mount to any flat metal surface on the vehicle, like the trunk lid, and it connects to a 4-Way on the towing vehicle. The benefit is that you do not have to cut into the vehicle...

  • Can A Magnetic Light Kit be Used at the Same Time as a Tow Dolly Light Kit
    As long as the power draw from the lights on the tow dolly and the magnetic lights does not exceed the amperage rating of the tow package wiring on the RV then you can just tap the magnetic kit into the tow dolly wiring harness. What I recommend is to tap into the tow bar wiring using the short wiring harness in # RM-2120 that you referenced. That way when it is not needed you can just put the cap on it and secure it to the tow dolly or RV. But you must make sure that the combined power...

  • 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...

  • Wire Functions of a Pilot Automotive Magnetic Towing Light Kit
    There really is nothing to installation of the magnetic light kit you have. You place the lights on a metal surface at the back of the vehicle and plug the 4-Way connector into either a 4-Way on the tow vehicle wide or to and extension and then to the tow vehicle. The light with a yellow wire going to it is for the driver side and the one with a green wire is for the passenger side. It will be nearly identical to the videos I have linked to the right. The wire functions are white for...

  • What Type of 4-Way Connector is Attached to the RoadMaster Standard Magnetic Tow Light # RM-2120
    The 4-way that attaches to the RoadMaster Standard Magnetic Tow Lights # RM-2120 is a female connector. It also comes with an extension piece that has a male end as well that does have a protective cover.

  • Compatibility of Roadmaster # RM-2120 Magnetic Tow Lights with 2011 Cadillac SRX
    When the # RM-2120 lamps are installed on your vehicle, they will operate completely independently of the lights on the towed vehicle. As long as your RV has a properly installed 4-way trailer connector for the magnetic lamps to plug into, all should work just fine. You mentioned that the RV has a 'separate' lighting system, which would use an amber turn signal bulb or have an amber turn signal lens. A properly installed 4-way will be already converted so the turn signal and brake lamp...

    There is no custom tow bar wiring harness for your 2005 Toyota RAV4, however I do have a solution for you. For lighting you can use the Magnetic Towing Light Kit, part # RM-2120. This kit offers easy hook up and removal with the non-scratch magnetic base. A 20 foot cord is included.

  • Flat Tow Light Recommendation for a Jeep Wrangler
    For a Jeep Wrangler like yours there really isn't a good place to attach magnetic tow lights like the part # RM-2120. You will need to attach a metal flap for them to attach to.. Check out the install video I attached as well.

  • Wiring Harness and Light Kits for Flat Towing With a 2004 GMC Sonoma
    The Magnetic Tow Lights, # RM-2120, plug directly into a 4-Way flat connector on the tow vehicle. If your are towing the 2003 GMC Sonoma behind another vehicle, I would need to know what connector the truck has at the front and what type of connector the towing vehicle has at the back. Then you can get an adapter to match. If you are using the Sonoma to tow another vehicle, I would need to know what it has on the back and what the other vehicle has on the front. There are several different...

  • Wire Span on Magnetic RoadMaster Tow Lights RM-2120

  • Recommended Magnetic Tow Lights That Plug Into 7-Way or 4-Way
    There are absolutely magnetic lights that will allow you to connect to either a 4-way or a 7-way. As you will see in the install video of the Roadmaster Standard Magnetic Tow Lights # RM-2120, you will choose whether you will use this product will a 4-way or a 7 way and purchase the appropriate adapter. After this initial setup, these will simply plug in, run the wire to the back of the tow vehicle and attach them magnetically. Very easy.

  • Can the Roadmaster Magnetic Tow Lights #RM-2120 be Mounted on the Inside of a Towed Vehicle
    As long as you can find a way to secure the Roadmaster Magnetic Tow Lights RM-2120 so that they don't fall over you should be good to mount them on the rear deck of your towed vehicle. If your rear window is tinted though it would be a better idea to mount them on top of your vehicle to make sure they are visible.

  • Where is the Best Place for Magnetic Tow Lights on a 2010 Chevy Colorado
    Roadmaster Standard Tow Lights # RM-2120 will work best on the roof of your 2010 Chevy Colorado. That is where the most metal, flat surface area will be. The magnets on these lights are strong so provided the surface they are on is flat then they won't fall off.

  • Are magnetic Wireless Tow Lights Submersible When Used On Boat Trailer
    You are correct. The Roadmaster Wireless Tow Lights are weatherproof and can be used when driving through snow or rain, but they are not submersible. They should be removed before launching your boat and then remounted when you pull the boat back on the trailer and ready to tow it again.

  • Is Replacement Antenna or Connector For Pilot Magnetic Lights Available
    You certainly aren't alone with this having happened, and we have checked with Pilot, but unfortunately there is not a replacement antenna or connector available for the Pilot Magnetic Tow Lights - Red LEDs - 4-Way Flat and 7-Way RV Connector - Wireless # NV-5164. So you will need to get the whole kit in order to get the connector as well, so while I know it's not the best news, you will at least have some replacement lights available should anything happen to yours in the future.

We have not had a chance to install this kit in a Sonic yet, but I can give you some measurements to help you determine if you would like to install this kit.

  • Wiring Recommendations to Flat Tow a 2013 Buick Enclave Behind a Motor Home
    A magnetic kit like # RM-2120 would definitely work since they bypass the factory wiring. These kits are ideal if you will not be towing the vehicle very often. A more permanent alternative if you will be towing the Enclave frequently and that still bypasses the vehicle wiring is a bulb and socket kit, # RM-155. The only things to think about with this kit are the space needed for installation and the drilling required. You will need at least 1/4 inch of space between the top of the bulb...

    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...

  • Can the Roadmaster Invisibrake be Used with Magnetic Lights on a 1997 Jeep Wrangler
    You can use the Invisibrake, # RM-8700, with a magnetic lighting system by splicing into the 4 wires on the magnetic lighting system. The only difference from the instructions is that the magnetic light ground has to grounded to the Jeep chassis rather than through the 4-Way connector. The brake switch is located above the brake pedal. On a 1997 Jeep Wrangler the wire you need on the brake switch is a white/tan wire. The easiest way to get to it is the direct approach.
