  • No need to wire your trailer or tap into wiring on your towed car
  • Wireless transmitter eliminates the hassle of running cords to the lights every time you tow
    • Plugs into 4-pole flat trailer connector on RV or tow vehicle and mounts to the frame with a magnet
    • Emits a signal that triggers tow lights from up to 65' away
    • Operates on a standard 12-volt system
  • Heavy-duty, non-scratch magnets on the lights provide a secure grip without damaging your paint
  • Long-lasting LEDs are more efficient, faster acting, and brighter than incandescent lights
  • Sonically sealed lenses keep moisture out and prevent corrosion
  • Durable polycarbonate bases house batteries
  • On/off switch lets you use the lights as needed, conserving battery power
  • 8 AA batteries (not included) are required to power the lights
    • Flashing LED on driver's-side light indicates low battery
  • Department of Transportation compliant


Specs:

  • Application: towed cars or trailers no wider than 80"
  • Light diameter: 4"
  • Length of wire between lights: 106"
  • Transmitter wire length: 76"
  • 90-Day warranty


Hopkins Tow Lights mount on the back of your towed vehicle.

These wireless, removable tow lights make it easy to add running lights, brake lights, and turn signals to your towed car or trailer. With this setup, you won't need to tap into existing wiring for installation. With other magnetic tow lights, you have to run cords from the lights to the front of the towed car or trailer every time you need to tow. These tow lights work wirelessly to eliminate that hassle. And the wireless design also allows you to move the lights from one vehicle to another in minutes.


Hopkins Tow Lights magnetic base.

The lights attach directly to any metal surface with the included heavy-duty, non-scratch magnets, which won't damage your paint. And the handy on/off switch lets you use the lights only when you need them, saving battery power.


The 4-way connector plugs into your vehicle.The transmitter attaches to your tow vehicle via a heavy-duty magnet.

Setup is simple. Plug the included transmitter into the 4-way flat trailer connector on your RV or tow vehicle. The transmitter mounts to the frame of the RV or tow vehicle using the built-in magnet. Turn the switch on the driver's-side light to "on," and attach the tow lights to the back of the towed car or trailer, as far apart as is practical. Secure any excess wire between the 2 lights with a twist tie.


Each light is powered by 4 AA batteries (not included). A blinking LED indicator on the face of the driver's-side light signals low battery. This indicator should be checked every 2 hours to be sure your lights still have adequate power.

Used these to tow aluminum body F150. Magnets strong enough to securely attach below rear bumper which is about the only steel part available. Super easy to set up and they work perfectly

They work great on my Class C pulling my Honda CRV.



by:
2019 Thor Windsport Motorhome

I just received them and tested them out and they work great. They are very bright and responsive. I look forward to using them in the future when I tow my vehicle behind my RV.

Haven’t used it yet. Looks good and delivery was fast.

Very bright and quite easy to install

VERY GOOD SERVICE I HAVE ORDER THINGS FROM FOR YEARS I THINK THEY ARE THE BEST BAR NONE



by:

Have issues with lights blinking erratic



by:

Ordered these because my car towing wiring had a problem and didn't have time to get it fixed. First set arrived but had a manufacturing defect and right hand light didn't work (not etrailer's fault!). Called etrailer and they were very accommodating in sending out a second set which arrived in time. The second set worked perfectly. Good service and extensive follow up by etrailer shows they care. I'll use them for other purchases any time!

Still works great. Save us on a trip when the car to RV connection went [bad].



by:

No big deal, install batteries and put on toad !

Should have done this years ago before they cut into my tail light wiring and also had to deal with rusted out 4 prong plug in over the years.

Still the best and not a problem, quality product



by:

Test connection went perfectly. Will see how it goes when we hit the road in May. The lights look well made and should last me a long time.

Thank for the great service!

Wonderful product

Lincoln MKZ

These things are the best thing since sliced bread!
We have a Lincoln MKZ that already has a hitch on the rear for towing a small enclosed trailer. The thought of having to "hard" wire in a wiring harness for towing behind the motorhome that would still allow the trailer to be towed was not a task I was looking forward to. etrailer suggested these as an alternative. Literally plug and play. Just plug the transmitter into the motorhome, install batteries and attach the magnetic based lights to the trunk of the MKZ and presto! DONE! I hooked the car up behind the motorhome and ran it down the freeway at 60-65 mph and all was good. Worked straight out of the box! Fantastic product!



by:

Works great no problems easy to install



by:

Great looking lights, LED wireless hook up makes this an easy installation and easy choice.



by:
Saturn Ion

These work well, bright. They do eat up regular Duracell batteries. After first use of these I switched to Lithium Ion. The lights were noticeably brighter in the daylight sun. The life of the batteries has drastically improved service. I have a habit of removing the batteries when not in use to enable greater duration; they do have an on/off switch built in, but it's so simple to remove them in case of phantom degradation. Over-all, I am very happy with these and installation on the car is a snap. Love them so far. Would buy/recommend to others.



by:
2011 Ford Taurus

Was absolutely 100% delighted with this product. Drove a total of 2600 miles in all kinds of weather and traffic conditions and these lights worked perfectly. Batteries lasted all most to the end of the trip. I'd recommend this set up to everyone who cannot afford to have wiring redone on a vintage trailer.



by:

very easy to see and use. I hope I never have to rewire another old trailer. Love them.



by:

I bought the wireless Hopkins tow lights to temporarily tow my new Jeep behind our Motorhome until I could wire the taillights permanently. I liked them so well that I have never wired the Jeep and only use the wireless taillights.



by:

Great customer service



by:

Great experience.Fast service.



by:

These have been a lifesaver for our camper lights not working properly. Never had an issue with these



by:
2010 Honda Element

I have not tried this yet, but the design is excellent! Having a magnet on the transmitter to attach to the tow vehicle was just icing on the cake!



by:

Great system



by:

Product appears to work as represented. Have not had it on the road yet.

Lights work great, and battery life is better than expected. Only issue is potential for paint damage... I recommend that the manufacturer consider a softer landing pad to reduce potential for paint scratches.

works just like Quinn said

  • How to Use Hopkins Magnetic Tow Lights With Supplemental Braking System
    My Recommendation is to use the Hopkins Endurance Multi-Tow Twist-Mount 7-Way RV and 4-Way Flat Trailer Connector, # HM40920. This provides the 7-way RV style you already have in place with a 4-way flat along side of it. Connect your Hopkins Magnetic Tow Lights, # C6304 with the 4-Way connector.

  • Tail Light and License Plate Solution for Transporting Covered Bikes
    The best solution we have is to use the Thule License Plate Holder # TH35JV for the license plate part of your problem and then adding magnetic towing lights like the Wireless Hopkins # C6304 (you need 8 AA batteries # DU58QR) or Optronics # TL21RK so your tail lights are still visible. Since your Swagman XC2 Bike Rack # S64650 will be covered with the bag you'll need to get creative with the mounting straps for the Thule License Plate Holder but it's the best option for your application.

  • Recommended Wiring Harness To Add Extra Visibility to Mercedes B200 on Tow Dolly
    For a Mercedes B200 there is not a custom wiring harness. Your vehicle is not intended to be flat towed so there is not a harness for wiring to do so as it should be towed with a dolly an thus have the lighting required. If you choose to add more lights to your tow dolly application, you can use a universal wiring harness like the Hopkins Magnetic Tow Lights - Red LEDs - 4-Way Flat Connector - Wireless # C6304 to give you the additional lighting.

  • Troubleshooting Magnetic Trailer Light Set Operation
    The ground circuit for this type of lighting is all tied to the white ground wire. First step I recommend is using a Test Light # PTW2992 to verify that the issues is with the light string and not the vehicle's 4-way. Looking at your 4-way plug connector it looks like you have 2 wires switched. The green wire is for your right turn signal/brake light and the white wire is the ground which both are correct on the 4-way. The yellow wire is for the left turn signal/brake light and brown...

  • Availability of Plug-In Tow Bar Wiring Kit for 2020 Jeep Wrangler Unlimited
    I do have a great lighting solution for you, however the Hopkins Custom Tail Light Wiring Kit # HM56200 that you referenced won't work on your 2020 Jeep Wrangler Unlimited. This custom harness is designed to fit earlier model Wranglers (up through the 2018 model year) and isn't compatible with the new generation. There isn't a similar custom plug-in harness available for your Jeep. If you'd rather not splice into the factory wiring on the vehicle (which I can certainly understand) another...

  • Is The 7-Way Connector For The Pilot Magnetic Tow Lights Available As A Replacement?
    This isn't the first time that this has been asked, however the 7-way connector part of the Pilot Magnetic Tow Lights NV-5164 is not offered separately as a replacement unfortunately. However, I know it's not ideal, but in order to get the replacement 7-way connector you need, you'll need to purchase the entire kit again.

  • Base Plate Kit for 2013 Mini Cooper Convertible Towed with Demco Tow Bar
    We don't have any Demco base plate kits that fit your 2013 Mini Cooper convertible, but we do a Roadmaster with the part # 521879-1A but it would only fit if yours is an S model. You'd be able to use your current Demco tow bar with it with the adapter part # RM-033. For a wireless tow bar lighting solution that has two different light assemblies you'd want the Hopkins Tow Lights part # C6304.

We also have a Hopkins wireless kit # C6304, available at a higher price point, which requires use of 8 AA batteries but which gives a range of up to 65-feet.

  • Parts Needed To Flat-Tow 1995 Jeep Wrangler
    When flat-towing, there are 5 things that are needed. For your 1995 Jeep Wrangler, the RoadMaster Tracker Tow Bar , part # RM-020, is one part of the system, and will work well for you. The base plates I recommend are the Roadmaster Base Plates, part # 1409-1. These brackets have a fixed-bar design and will work well with the Tracker tow bar. I then recommend the RoadMaster Coiled, Safety Chains, part # RM-643. These vinyl-coated cables have a quick link on one end and a spring hook on...

  • How to Tow a 2008 Mini Coops S with Sport Suspension Behind Motorhome
    Snice your 2008 Mini Cooper S has the Sport suspension you'll need to use a tow dolly to tow your vehicle behind your Winnebago instead of a standard flat towing setup that uses a base plate kit. I recommend going with the Demco Kar Kaddy SS # DM9713045 because it comes with surge disc brakes and has the ability to fold which makes storage at home and the campsite much more convenient. This tow dolly comes with brake lights already and a connector for it as well. Since your RV has a 6-Way...

  • Magnetic Flat Towing Light Recommendation that are LED and have 4-Way Flat Connector
    The bulbs of the Roadmaster Standard Magnetic Tow Lights # RM-2120 are incandescent, they are not LED. A better option would be the Hopkins Magnetic Tow Lights # C6304. This kit uses LEDs and comes with a 4-way flat already. I attached a review video for you to check out as well.

  • Tow Lights for 2013 Hyundai Sonata on Tow Dolly
    It sounds like you're wanting to tow your 2013 Hyundai Sonata on a tow dolly that does not have lights. By far the simplest way to go about this is to use a set of tow lights that have a 4-pole connector. These provide an easy plug-in installation and don't require you to start cutting into the car's wiring to install a diode kit like # TR118821. Examples of such light kits include the magnetic # RM-2120, and others like the # C6304 from Hopkins.

    Along with the Blue Ox Base Plate Kit # BX1716 and the Blue Ox Alpha 2 Tow Bar # BX7380 there are a couple more parts you need in order to safely flat tow your 2016 Cadillac Escalade. Since the Alpha comes with safety chains we can check that off the list but you will also need a wiring kit in order to activate your Escalade's brake lights and turn signals. For that the best option is the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267, or you can simply add magnetic...

  • Inexpensive Tow Bar for a 2003 Honda Civic EX
    The Curt Tow Bar with Adjustable-Width Arms part # C19745 would not mount directly to the front bumper fascia on your 2003 Honda Civic EX because it is made of plastic. In order to use this tow bar you would need to remove the front bumper fascia and attach this to the bumper support beam or the core support arms. If you do not want to remove the front bumper fascia each time then your only option would be a set of base plates and tow bar. The cost cost effective option we have for this...

    The closest thing to what you described would be the Hopkins Magnetic Tow Lights # C6304. These are tow lights designed for temporary use when flat-towing.

For Tow Bars I recommend the Blue Ox Alpha part # BX7380. This comes with safety cables. For lighting I would recommend the Hopkins Magnetic Tow Lights # C6304.

  • Parts Needed to Flat Tow 2016 Jeep Wrangler Unlimited Behind 2013 Toyota Tundra
    Flat towing a vehicle behind another vehicle takes a few components including the tow bar, safety cables, a wiring or lighting kit of some kind, and a braking system for the towed vehicle. Since you are not towing with a motorhome you may not need a high/low hitch adapter to keep the tow bar level and since your towed Jeep has an aftermarket bumper you may not need base plates. You will want to confirm with the maker of the Jeep's front bumper whether that specific product is rated for...

    Based on your troubleshooting efforts and the fact that this product did not operate properly on both of your vehicles I am inclined to think the unit has a defect. But you can easily test it, independent of the vehicles, to isolate the location of the issue. Use a 12V vehicle or spare battery to apply power directly to the wireless transmitter portion of the Hopkins Wireless Magnetic Tow Lights # C6304.

    Since you have the 7-way and 4 way connections on your motorhome, you will have both wiring hot and ready to work. Some spring doors won't allow both to open at the same time like # HM40975 so some people will remove the door on the 4-way side to allow the door on the 7-way with the clip to help hold the 7-way plug in. Other styles like # HM40920 will allow you to use both connectors without any adapting necessary. It sounds like you are wanting to use the Roadmaster Tow Dolly # RM-2050-1...

  • Will Optronics LED Magnetic Tow Lights Protect Against Scratching 2018 Ford Fiesta SE Paint?
    The Optronics Magnetic LED Tow Light Kit - Weatherproof - Red Lens - 20' Wiring Harness - Qty 2 # TLL21RK has a protective label pad on the bottom to keep from scratching paint. You can see this at the 2 minute mark of the attached review video. I do recommend wiping down the vehicle with a microfiber cloth before putting the lights on simply to remove any dust or debris that could be abrasive between the scratch free label and the paint for added security.

  • Testing Operation of LED Magnetic Towing Lights
    The Hopkins Magnetic Tow Lights # C6304 you referenced require you to install 8 AA batteries in order to function so this is the first thing to check. LED lights of any type are generally highly electrically efficient. LEDs typically use about 1/10th as much power as an incandescent light. This high efficiency can sometimes "fool" certain vehicle's trailer wiring systems. In certain cases load resistors like # DI34ZR can be needed to mimic the higher power draw of standard incandescent...
