Magnetic LED Tow Lights

A towed vehicle is required by law to have functional brake and signal lights that illuminate at the same time as the brake and signal lights on the motorhome or RV that is towing it. These removable tow lights make it easy to add running lights, brake lights, and turn signals to your towed car or trailer.


Simply mount the lights on your vehicle's trunk or roof with the heavy-duty magnetic bases. A 63" long section of wiring connects the tow lights, giving you enough slack to position the lights where you want them. Then run the 245" long wiring harness up to the front of your towed vehicle and across your tow bar and connect it to the 4-way flat on your RV.


If your RV doesn't have a trailer connector, then you can wire the extra 35" long 4-way harness that comes with this kit to your RV. And if your RV has a 6-way or 7-way trailer connector, an adapter (sold separately) will be required to connect the tow lights to your RV.


Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

The wiring length should be increased by at least five feet. We have a small vehicle and still needed to use an extension. Otherwise it is a terrific solution.

Have not used yet but I think it will be great



by:

Bought these magnetic trailer lights for my hitch-mounted e-bike rack. With two bikes on the rack, the rear car lights are partly obscured. These lights attach firmly to the rack with the magnets but I will secure them with straps as the rack surface is rounded. Plenty bright. Haven’t gone any distance yet, but I will drive reassured that the cars behind will better see my braking and turning.

These work fine and are bright. I plant them behind my toad's roof rack and add a little duck tape for security. I have lost other ones before. It may be overkill on these as magnet is good.

I've seen magnetic tow lights before but not like these LED's. As soon as they arrived I opened them up, checked them out and they are very well built,the magnets seem very firm and they are BRIGHT. The video on the ETrailer site does no represent how bright these light are in my opinion. Very pleased with the quality and how visible these lights are.



by:

Great product, just as described. I am using it on my kayak trailer to replace the original incadescent lights.

  • What Lighting Requirements Are Needed When Dolly towing a 2013 Acura TL?
    I recommend first checking with the local laws where you will be towing your 2013 Acura TL. The tail lights on a Tow Dolly # DM9713045 are often the only lights which are required. If this is the case you will only need an Adapter # 337TC2074P to go from the 7-way on the motorhome to the 4-way flat on the trailer. If you require additional lighting I recommend adding the Magnetic LED Tow Light Kit # TLL21RK. This is a great option as you do not have to wire anything with your lights....

  • Recommended Components For Flat-Towing 2003 Honda Odyssey
    For your 2003 Honda Odyssey, I recommend the Roadmaster Base Plates, part # 521551-1. These base plates will fit your Odyssey whether it has the tow package transmission cooler or not. Some trimming of the spoiler or fascia may be required when installing these base plates. The tow bar you asked about, part # RM-501, will work well with the # 521551-1 base plates. I have attached a link to a product review video for this tow bar you can check out. Along with the base plates and tow...

  • Portable LED Lights with 4-Pole Connection
    Optronics LED Combination Tail Light Kit # TLL9RK has lights that use a separate white ground wire that normally would ground to the trailer. Then the trailer 4-pole wiring would in turn carry that ground back to the tow vehicle via its 4-pole wiring. One way or another these lights' ground must connect to the vehicle's ground. There is an easier solution for temporary lighting, a portable LED light kit like # TLL21RK. This kit includes two magnetic-base lights with a prewired 4-pole with...

  • Will RoadMaster StowMaster Car-Mounted Tow Bar # RM-501 Fit 2000 Toyota Echo
    The RoadMaster StowMaster Car-Mounted Tow Bar # RM-501 will work on your 2000 Toyota Echo if it is equipped with a compatible set of Roadmaster base plates such as their # 521156-1. These EZ-series base plates will work fine with the StowMaster tow bar and they install without welding using included hardware. Safe and legal flat towing requires some additional components to go along with the base plates and tow bar, as outlined in the linked article. Safety cables are required but these...

  • Availability of Base Plates for Flat Towing 2004 Honda Civic Hybrid Sedan
    Roadmaster and Blue Ox both offer base plates for the 2004 Honda Civic Hybrid Sedan and these can be seen on the link provided. Both feature twist-lock removable draw bars and both will require some trimming of the bumper fascia and other components. The Roadmaster kit is part # 521537-1 and the Blue Ox kit is part # BX2236. The Roadmaster Tracker tow bar # RM-020 that you referenced is compatible with these Roadmaster base plates so I suggest these for your application. Flat towing also...

  • Both Turn Signals Blink on MaxxTow Tow Lights # MT70097 When Tow Vehicle Signals Are On
    If both the left and right turn signals on your MaxxTow Tow Lights MT70097 blink when either turn signal is activated on the tow vehicle the first thing to check is the condition of both connectors. Since the left- and right-turn signal circuits on a 4-pole are adjacent to each other (green and yellow wires), it is possible that corrosion in the connector can cause these two separate circuits to become bridged together. This condition could also explain the dim light output, since two...

    To flat-tow your Hyundai Santa Fe you need 5 items. You will need base plates, a tow bar, safety cables, lighting for the towed vehicle, and most states now require supplemental brake systems.

  • Parts Needed to Flat Tow a 2006 Chevrolet Aveo
    Based on your previous questions, I believe you are looking for a base plate kit and tow bar to flat tow your 2006 Chevrolet Aveo behind a motorhome or another vehicle. If this is the case, then you will want a base plate kit like part # BX1658 and a tow bar like part # BX7380. Unfortunately a tow bar cannot be connected directly to the bumper because the bumper is not strong enough to pull the weight of the Aveo. A few other components that you will need to flat tow your Aveo are a...

  • Base Plates for 2010 Honda Element EX That Are Compatible with Ready Brute Elite Tow Bar
    The base plate I recommend for your 2010 Honda Element EX is the Blue Ox # BX2232. Our installers tend to prefer Blue Ox for their user-friendly features. Installation on a 2010 Element will require removal/replacement of the bumper fascia, some trimming of the bumper and minor drilling. You can use your Ready Brute Elite tow bar with these base plates by using the Blue Ox Base Plate Adapter Brackets for Ready Brute Elite Tow Bars, part # BX88297.

  • Which Type of Flat Towing Lighting Set-Up to Use for 2011 GMC Terrain
    The easiest type of flat towing lighting kit is the magnetic type like the Optronics # TLL21RK. These take only moments to install and are easily removed and stored when you're not flat towing. They require no alterations to your vehicle. A more permanent installation is a bulb-and-socket kit like # RM-155 from Roadmaster. This kit includes new wiring and separate bulbs that install inside the vehicle taillight assemblies. These remain electrically separate from the vehicle's internal...

    In order to flat tow your 2007 Ford Explorer behind an RV you will need a base plate kit, a tow bar, safety cables, a lighting solution, and a supplemental braking system. The most economical base plate kit we have available for your Explorer is the Roadmaster XL Base Plate Kit # 4405-1.

  • Recommendation for Flat Towing a 2013 Chevy Spark with Manual Transmission
    First let's get you set up with a base plate kit. The Blue Ox # BX1722 is the custom fit base plate kit for your 2013 Chevrolet Spark with a manual transmission. Next we will need a tow bar. I recommend the # BX7420, because it's easy to use and comes with the safety cables. Supplemental Braking Systems are required in most states and Canadian provinces, so you will want to look up your state and see what towing laws they enforce. Surge brakes operate by using a mechanical braking...

If you have a Roadmaster StowMaster Tow Bar like part # RM-501, it will attach to the base plates with the plate on the towbar crossbar. If you need the Quick Disconnect Kit for your StowMaster tow bar the part you need is part # RM-201. If you have the Edge model, the base plates would...

I have linked for you the written installation instructions and also a video showing an application in a 2014 Equinox. A fully-compatible and popular tow bar for use with these plates is the Blue Ox Alpha, part # BX7380, which is a motor home-mount tow bar that includes the required safety cables. This spares...

  • Magnetic Versus Wired Magnetic Towing Lights For Long Road Trips
    If you were to go with the either the Custer Wireless LED Tow Bar Light 4-Way # LIW-LDTL or 7-Way # LIW-LDTL-7B I recommend getting 2 of these. That will allow you to have one in the cab charging while using the other one. As they have an expected battery life of 6-8hours per charge this will allow you to switch them out as you stop for gas or food. Otherwise the Magnetic LED Tow Light Kit # TLL21RK will provide you with 20' of wiring to use hard wired lights. These lights uses LED's...

If you are looking to add the cargo box lights as supplements to your standard flat tow lighting you will want to consider a few things. First, additional lights will demand more power and so I suggest using high-efficiency LED type lights that will be...

You will need base plates, a tow bar, a wiring kit, safety cables and a supplemental braking system.

To determine this, I recommend checking your owners manual under the recreational towing section. From my research, I could not find any information that showed...

    I certainly understand your desire to keep the cost to flat tow your 2004 Honda CRV as low as possible.

What I am recommending is not the most inexpensive way to flat tow but it is the most effective at a reasonable price. To flat tow your 2004 Honda CRV, you will need base plates, a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For base...

    If you have anti-sway on your 2015 F-250, adding weight to the rear of the truck may not keep the system from becoming activated. The best solution would be to go slower when driving on roads with uneven surfaces. The # RP66022 you came from is a weight distribution system that is intended to be used with trailer towing and is not designed to flat-tow a vehicle. There are 5 items needed when you flat-tow a vehicle. If you do not have all the items needed I will make some recommendations...
