A towed car 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 RV that is towing it. Most wiring kits require you to splice into your Chevrolet Suburban's electrical system to install diodes, but doing this can void your manufacturer's warranty. You also run the risk of making a mistake during installation that could result in potentially damaging electrical feedback. Magnetic tow lights eliminate this problem because they bypass your car's electrical system entirely and leave your wiring intact. Just mount the lights on your Chevrolet Suburban's trunk or roof with the heavy-duty magnetic bases. Then run the wiring harness up to the front of your towed car, across your tow bar, and then connect it to the 4-way flat on your motor home or tow vehicle. If your tow vehicle doesn't have a 4-way, an adapter is required.
This kit includes a 20' long wishbone-style wiring harness with a 4-way flat connector on the end. A separate 3' wiring harness with a 4-way plug can be used to install a 4-way on your tow vehicle or RV if it does not already have a trailer connector. Quick-splice connectors are included if needed. A 4-1/2' long harness connects both lights, giving you enough slack to position the lights where you want them.

Overall it worked fine. Easy to use. We did encounter some high winds that twisted the light sideways once. Magnet strength otherwise is strong enough.

A very easy way to light my jeep when towed without having to cut into the jeeps wiring system.

Thank you for the quick service. I appreciate that they were able to accommodate my need of replacing my wiring harness.

Haven’t used them yet but they look good and I’m sure they will do the job.

This didn't work out of the box! The passenger side would not function at all. No tail, brake, or turn signal. Etrailer is issuing a return for refund. I had to leave for a camping trip, so I went to Harbor Freight and purchased an LED set for a little over half of what these cost; and these aren't LED.

works great for towing my jeep. just plug the four flat into the factory trailer wiring on the tow vehicle, set the lights on the bumper and they work perfect. the magnets are strong but the thicker the metal they are on the better they hold. steel on my bumper is thick enough for a strong hold but I tried thinner metal and the hold is weaker so you may need to add some straps
by: Ed F06/09/2017
The product arrived quickly and was exactly as advertised. The light kit is the perfect solution for the car I tow behind my RV, but also use by itself. I like the fact that it is totally portable, mounts high up on the vehicle for good visibility and is quick and easy to install when needed.

Worked perfect. I have since gone to anew vehicle with integrated light wiring. I sold the lights to a friend and he has been happy since!

I am very happy with this purchase. The magnets in the base of the lights keep them connected to the roof of our towed car, no wobbling! The signal wire is long enough to run through our 2019 Honda Fit and connect with our tow vehicle. After getting wet several times, the protective sticker on the bottom of the lights wore off and now the lights have left slight scratches on the roof of the car, nothing major. On the roof of our towed car, they are seen from a distance and work with the tail lights of our motor home just fine.
On occasion, we have to wiggle the wire coming out of the light to get it to work, but this is after a year’s worth of intermittent towing and I’m pretty sure we bashed them around a little. Great product at a great price, professional installation is not necessary. A little better construction and this would be a 5 star rating.

I am using these for added visibility on the back of a large bike rack that pretty much stays on the car all the time. I do not suggest using the magnets as the only form of attachment as they are not strong enough to keep the lights attached when going over bumps. I zip-tied them to the frame of the bike rack. At first, I had them sticking out from the bottom of the rack, and they were fine until I went up a steep hill and one of the lights got knocked off on the road. These lights are extremely well-built because instead of snapping the light, the rather large zip-ties broke. The light still works great after the incident. I now have them sticking out the sides to give more ground clearance, and they seem to be doing fine. For my application, I had to replace the wire between the lights with a longer one, but that was not difficult and will not be necessary in a typical application. At least the lights are easy to disassemble to access the wiring. The only way these could be improved would be to add strong neodymium magnets and to make the red lenses screw on (instead of snapping on) for easier access to the bulbs for replacement. Otherwise, a perfect product.
For the record, I did not need to use the included vehicle wiring harness or splice connectors, since my application required an electronic light controller.
by: Amy11/27/2017
The magnets didn't stay on the car so I ended up permanently gluing them to my roof since we tow our car behind the rv full time. Had to replace the bulbs with LED bulbs since our rv tail lights couldn't supply enough voltage to the incandescent bulbs to see them in daytime. This isn't a failure of the product but rather an undiagnosed voltage problem with our rv. With those modifications I am happy with it.
by: Big Donald01/14/2021
I got this because the lights on the trailer for my 15' Boston Whaler kept getting broken while launching. Now, I just have to hook these on before I hit the road (easily by magnet) and I can take them off before risking damage while launching. Perfect! Just make sure the wire is long enough. It just fits my little trailer, but a longer one may need an extension wire harness.
by: Doug Q05/28/2013
Perfect, just what we needed to get our trailer home from storage so I could work on the finding the root cause for the failure of the permanent trailer lights. Now that the permanent lights have been fixed, the temporary magnetic lights are stored with the trailer sort of like a spare tire, knowing how fiddly trailer wiring can sometimes be. It's worth the small investment for the extra measure of safety in case the permanent trailer lights fail again far from home.
by: Michelle08/01/2017
etrailer was easy to order from and shipping was fast. However, I ordered this specific light set to fit my standard 4-way flat connection that already exists on my trailer and did not plan on doing any wiring on my truck. Unfortunately, it does not fit. I will have to buy a converter or something I guess. I emailed them with this issue asking if this light is not a standard 4-way flat and haven't received a response.
Seems to be a nice sturdy light set. Doesn't help when I can't use it, though.

Everything needed for my application. Easily moved from tow dolly mount to fender of vehicle being towed.

One-and-a-half years later I am still using the tow lights regularly and they still work and look great!
by: tfs07/04/2016
Strong magnets hold the lights in place even on a bouncy trailer. Lead wire length is sufficient for the average towing vehicle or trailer. My only complaint is that the wire length between the two lights needs to be a foot longer for my uses.
by: Michael L.01/06/2012
I purchased a Curt hitch for my 09 CRV. I also bought a wiring harness and a set of magnetic lights for attachment to vehicles. I was able to install the hitch in less than an hour. It took me 30 minutes to connect the wiring. The lights are very simple to connect and only hook up one way. The instructions included links to videos that made the job a snap. The instructions said to put the wiring inside the car by the spare tire when not in use to preserve the connector. what a great suggestion! I did not put a single mark on the car and the hitch looks great.

They say that a company is only as good as its employees... Well, etrailer is extremely fortunate to have someone like Shawn B. Working for them! This young lady got me out of a really frustrating predicament, and through careful listening and asking the right questions, she saved me not only a ton of money, but a whole bunch of frustration as well! My dilemma was that I had purchased a Jeep Liberty with a Blue Ox base plate, but I had a Blackhawk 2 tow bar! I thought I was going to have to go out and buy a Blue Ox tow bar to use with the Blue Ox base plate, but through careful review of my situation, and a calm analytical approach, this young lady determined exactly what I needed in the way of adapters and a towing light set up! Today, more than ever, it's all about customer service, and that is exactly what she provided for me!
by: Steve S-omaha09/17/2016
After struggling with my trailer lighting system for years, I gave up and bought a portable system from etrailer. Within 5 minutes of unwrapping it, everything worked great and I am not longer spending hours trying to trouble shoot the old system. The magnets that hold the lights on the trailer are very strong, but I still use a bungy cord on each one just in case I hit a large bump in the road.
Thanks etrailer, excellent product!

Nice magnetic set. I bolted small steel pieces to my ranger bumper because it is covered in plastic. An easy hack located them just wide of the tailgate so it could open with lights in place. Drove 1200 miles with no problems.
by: Matthew08/10/2021
Used on tow car over the last year - towed at slight angle via tow-dolly. Driven 1000's of miles with this on the tow car through rough storms and strong winds - have not experienced an issue. Strong magnets have not scratched the vehicle. Would purchase again.

Strong magnets. I needed an extension to plug the lights into the tow vehicle. The wires could be longer between the lights.
by: Jason H08/23/2020
Plenty of cord. My only desire would be the magnets be on the back of the lights, not the bottom. But I made it work. Used this to make my bike rack euro compliant for lighting.

I needed to move a trailer to a location where I could troubleshoot and repair the trailer lights. Worked well, good price, and reasonable shipping cost, After I had used the lights I happened to see a similar setup at Walmart which was $10 MORE than the total I paid etrailer.

- Parts Needed To Flat Tow a 2019 Chevy Colorado ZR2In order to flat tow your 2019 Chevy Colorado you will need a tow bar (which you already have), base plates, tow bar wiring, safety cables, a supplemental braking system and a high/low adapter. I've gone ahead and put together a quick list of the parts we recommend in each category below. Base Plates: Roadmaster Direct-Connect Base Plate Kit - Removable Arms # RM-523182-5 (compatible with your Roadmaster Falcon # RM-520 or # RM-525 tow bar without a base plate adapter) Safety Cables:...
view full answer... - Recommended Tow Bar Wiring for 2016 Ford F-150You are correct that aluminum doesn't work well with magnets. The Heavy Duty Magnetic Tow Lights - 20' Wiring Harness with 4-Way Flat Trailer Connector # TL21RK can only be attached to the cab of your truck if you choose to use them or to a steel bumper. I recommend using the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56009 instead. This harness connects behind your tail lights to your factory harness and then you simply run the connector on the harness to the front...

For a complete flat towing setup you will need a base plate kit, tow bar, safety cables, vehicle tow bar wiring, a supplemental braking system, and possibly a high-low adapter. If you do not have all of these components then I recommend picking up the following: EZ Base Plate Kit - # 521181-5 StowMaster Tow Bar - # RM-501 Safety Cables - # RM-643 Wiring...

view full answer... - Explaining Wiring Connections on Yellow and Brown Wire of Tow Ready Tail Light Isolating DiodeI found the portion of the install video of the # TR118821 that you mentioned and to clarify what he's doing he's splicing in the wiring from the kit to the wiring of the vehicle in a way that allows the vehicle wiring to still function like it needs to and also allow the converter box to get the signal it needs to from the circuits. So he's cutting the vehicle wiring and putting the vehicle wiring and the converter box wiring in one end of the butt end connector and then the other end...

In order to install this towbar you will need to remove the bumper and attach it to the vehicle's core support somewhere. There are no speed restrictions for tow bars like the above. If a speed restriction is present, it will be from the owner's manual to protect the vehicle. The Curt Tow Bar will maintain its warranty...

Page 4-26 of the online edition of the owner's manual indicates that one version of the car cannot be flat towed, that version being the 3.9L V6 engine with the four-speed automatic transmission.

view full answer... - Does my Tow Bar Wiring Harness Require the use of Hy-Power DiodesWherever you use the RV to signal the vehicle's factory lights, diodes will be needed to stop the backflow of electricity. If you are using a set of external lights like part # TL21RK then the diodes will not be needed but since you have the wiring harness attached to your factory lights then you will want to use a set of diodes like part # RM-794. I have attached a diode installation help article for you to take a look at as well.
view full answer... - Types of Flat Tow Wiring Kits for 2015 Ford FocusFlat towing base plates like the Blue Ox kit # BX2654 for the Ford Focus, the item that you referenced, do not include wiring. The reason is that there are several different types of products to provide the electrical/lighting connection between a motorhome and towed car and some owners may have a preference for one or the other. For example, for the various versions of the 2015 Ford Focus we have flat towing wiring products (shown on the linked page) that include inexpensive magnetic...

I attached installation instructions for this base plate kit for you to check out also.

We carry basically everything but the drive shaft disconnect. You can use the Demco tow bar part # DM9511012 that you referenced.

If you choose to disconnect the drive shaft as you stated, you may be able to use a tow dolly like the Roadmaster Tow Dolly with Electric Brakes - 4,250 lbs # RM-2050-1.

There would be some extra wire you'd need to bundle up and secure with zip ties, but the installation would be very simple. Another option would involve using a light kit designed for a cargo carrier. I'd recommend the # 98174LED kit and...
