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.

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

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.


Very bright and quite easy to install

2003 Chevrolet Malibu



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!

John K.


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


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!


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.

Tom M.


Still the best and not a problem, quality product


Wonderful product


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

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!


Works great no problems easy to install


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.

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.


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

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.


Great customer service


Great experience.Fast service.

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!


Great system


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


works just like Quinn said

2020 Ford F-350 Super Duty

Great service, fast delivery and we’re very pleased with product


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.




It has worked out fine and as advertised. the manufacture needs to work out a quick charge system, with external jacks, or a large external rechargeable battery pack for tow-able vehicles for RVs that go on multi day tows.


will send back does not work



Have to use lithium batteries for them to work, I have a set and mine work with this type of battery in them only thing that needs improvement is they should be rechargeable units

  • Troubleshooting Hopkins Wireless Magnetic Tow Lights C6304
    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. Connect the battery ground to the pin for the white wire and then apply the battery...

  • How to Access The AA Batteries For Replacement on the Hopkins Magnetic LED Tow Lights
    The Hopkins Magnetic Tow Lights # C6304 will have 8 AA batteries total with 4 batteries in the base of each light. The base twists off allowing you to access the batteries for replacement. There is also a switch on the base of the drivers side that allows you to turn the lights off when not in use to conserve battery life. When you see flashing on the drivers side light, this is an indicator telling you the batteries are low and need replaced.

  • Troubleshooting Hopkins Magnetic Tow Lights that Dont Want to Power On
    In order for the # C6304 to function you would need to make sure that the batteries are installed properly in the light kit as well as make sure the power switch is turned on. This switch is at the bottom of one of the lights in a recessed opening. Check out the video I attached that covers everything on these lights if you have further questions. Or you can email me back if you are still having troubles.

  • 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.

  • Where Should I Stick My Magnetic Tow Lights On My Ford Maverick?
    If I were you, I'd just stick the lights # C6304 to the roof of your Maverick and call it good. They'll be up high enough where anyone on the road will be able to see them, and they won't potentially slip off because they're getting ideal metal on magnet contact.

  • 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.

  • Troubleshooting Wireless Tow Dolly Lights Where Only Left Tail Signal Works
    You've narrowed the problem down to being the wireless tow lights since you've tried them in a few vehicles with the same result. The easy solution would be that there's corrosion on the pins of the 4-way connector which is preventing the circuits from working like they should which would easily be fixed by taking sandpaper to them to clean them off. If it's not that though it's most likely an internal issue with the transmitter or the lights themselves.

  • Can I Connect The Hopkins Magnetic Lights To 4-Pin and Still Use Brake Controller
    The Hopkins Magnetic Tow Lights part # C6304 are designed to be plugged into a 4-pin connector on a towed vehicle. If you want to use these on the vehicle and plug them into the 4-pin on the trailer you would not have the running lights on your trailer. Also it sounds like you are having an issue with the trailer wiring connector on your vehicle anyway if the trailer lights are not lighting up. I recommend to check the 4-pin wiring on the 2019 Land Rover Discovery for any damaged or frayed...

  • Will the Tekonsha T-One # 118461 Carry the Emergency Flasher Signal on a 2009 Subaru Outback Wagon
    Yes, the Tekonsha T-One # 118461 uses a standard 4-Way Flat connector which carries running lights, left brake/turn signal, right brake/turn signal, and the ground. The flasher signals would draw off both the left brake/turn signal and the right brake/turn signal. This is a confirmed fit for your 2009 Subaru Outback Wagon and I have attached an installation video for you to reference. If you don't already have lights I recommend the Hopkins Magnetic Tow Lights # C6304. These don't connect...

To easily add a 4-way you could use the part # 118384 which will plug inline with your 7-way.

    I do have an option for you but I am not aware of any way to flat-tow a vehicle using a front mount trailer hitch as there would be no way for the wheels to track properly. The most cost effective option we have for you to attach the Cherokee to your pickup is with the Curt Tow Bar with Adjustable-Width Arms part # C19745. If you don't have a steel bumper on your Jeep to attach this tow bar then you will need to remove the bumper and then attach this to the vehicle's core support. In...

  • Can a 1995 GMC C/K Series Pickup Be Towed Behind Another Vehicle
    It is possible to flat-tow a 1995 GMC C/K Series Pickup. However, you will need a lube pump if you have a C1500 or you will need to disconnect the drive shaft if you have a K1500 without manual transfer case. In order to flat-tow the vehicle you will need a tow bar like the Curt Tow Bar with Adjustable-Width Arms part # C19745 and a lighting kit like the Hopkins Magnetic Tow Lights part # C6304 at the very least.

  • Does Heat Affect Hopkins Magnetic Lights
    Thank you for your purchase directly from etrailer of the Hopkins Magnetic Tow Lights # C6304. It may be possible for extreme heat to affect any electronics, though it's impossible to say if that is the cause. Since you already tested the lights and it shows a connection, really the only thing to do is get a replacement, there isn't a fix for this. It does have a 90-day warranty, though if that is out I would consider something more robust, like the lifetime warranty that comes with the...

Running light signals are carried on the brown wire in 4-pole wiring. If you are not getting that function on the lights you can check that the four batteries in each light are all good and that the pin on your vehicle 4-pole does not have any corrosion on it that could be blocking the signal.

  • What is the Battery Life for Hopkins Wireless Magnetic Tow Lights
    The battery life for Hopkins wireless magnetic tow lights, # C6304, is going to depend on several factors including the charge level of the batteries used, quality of the batteries, ambient temperature, and of course how long the lights are turned on. It is difficult to estimate because of all of these factors. The safe bet is to check them with reasonable frequency. With that said the LED lights draw very little amperage so fresh batteries are likely going to last well over 2 hours. If...
