Great service and lights worked great with yellow coiled 3’ RV to Flat plug adapter! Had to extend the width of the lights to fit around Jeep, used extra flat plug wire in kit! Simple and fast setup works great! Great service and follow up from etrailer.com!

Just got it in and it looks great. Anxious to use it. Seems perfect for my Jeep pull behind my motorhome. Hooked it up to make sure that it worked last night.

- 73864

Poor rating for my application. I used these as a magnetic light on a bike rack and as such had them mounted upside down on that rack and then secured. They can’t be upside down or they collect rainwater as mine did through an opening at the bottom of the lease. They were no good after one food rain storm while driving. I Ultimately had to replace them due to the water damage and with a different light but kept and used the wiring harness however and have had no issues with that :).

Needed these lights for my towed vehicle and they were delivered promptly and seem to be just what I need to avoid rewiring my new truck. etrailer is my first choice for this type of equipment and they continue to deliver (no pun intended)

- 73864

Site is easy to use. Price are good. Item was shipped fast. Untested as of now, but other things I've ordered from etrailer have been fine.

The wiring is still fine. Weve used it a whopping two times. Its not worth another review, but I thought Id at least let you know.

These lights work perfectly mounted on the bumper of my ranger. I did not want to splice into the rangers wiring so this unit was the solution.

  • Most Cost-Effective Way to Flat or Dinghy Tow a 2020 Ram 1500
    I'm glad you know that there is going to be a certain cost associated with flat towing (also called dinghy towing) your 2020 Ram 1500, but there are certain ways you can save money while still being both safe and comfortable. There are a number of parts you'll need, starting with base plates, the Roadmaster Direct-Connect Base Plate Kit # RM-522203-5 (fits all but Rebel models of '20 Ram 1500), which also needs a compatible tow bar, with the Roadmaster Falcon 2 Tow Bar # RM-520 being...

  • Which Style of Tow Bar Lighting is Easiest to Install and Use
    When flat towing a vehicle magnetic tow lights like the Tow Ready kit part # 73864 really are the easiest solution to deal with. It's just a matter of plugging them in and setting them on a metal surface that's visible and you are good to go. I attached an install video for these for you to check out as well.

  • Will the Tow Ready Magnetic Tow Lights Part # 73864 Scratch My Paint
    There is a protective film on the bottom of the Tow Ready Magnetic Tow Lights part # 73864 that will help prevent the base from scratching your vehicle's painted surface. I have attached a photo for you as well that shows the protective film. Please make sure the surface that you attach the lights to is clean as this will also help to avoid scratches.

  • Recommended Removable Flat Tow Light Kit For 2016 Jeep Wrangler Soft Top
    I may have another option but we do not carry the Custer Ez Mount EZT20B that use a mounting flap. We have had customers use the Tow Ready Magnetic Tow Lights # 73864 on their Jeeps by attaching the magnet to the body right next to the tail light housings. I included a picture of the lights used this way on a Jeep Wrangler for you to take a look at. This would be a great removeable option for your 2016 Jeep Wrangler with a soft top as it would still allow you to easily remove the...

  • Magnet Strength Of Tow Ready Tow Bar Wiring 18148 Lights
    The Tow Ready Magnetic Tow Lights - 4-Way Flat Connectors # 73864 have a strong magnet. They don't have any weight rating or capacity rating. They have been tested at highway speeds with various weather conditions to stay firmly in place on your towed vehicle's exterior. You can remove them by hand and they take a little strength to remove, but you do have to be purposeful for them to come loose. I've attached an article on these style magnetic lights to assist.

  • Can Tow Ready Magnetic Tow Lights # 73864 be Mounted to Side of 2016 Jeep Wrangler
    If you have a strong magnetic surface on the side of your 2016 Jeep Wrangler you could very well mount the Tow Ready Magnetic Tow Lights # 73864 there. The magnets are very strong for the lights, but we haven't tested them on the side of a vehicle so there isn't a way I can guarantee that it will hold well. You may want to check out these Demco lights with wiring harness. They uses suction cups and straps to mount to your trunk or roof. Since these do not require a magnetic surface...

  • Will SMI Delta Force Portable Braking System Work on 2019 Honda Fit
    Yes, the SMI Delta Force Portable Supplemental Braking System # SM99242 will work perfectly on your 2019 Honda Fit. Whether or not a system like this will actually activate the brake lights when pressing down on the pedal depends on the specific vehicle it's being used on (how the tail lights function when in the correct mode for towing). Based on my research though the brake lights for your 2019 Honda Fit should indeed still illuminate when the Delta Force applies the brakes. This...

  • Gauge Wire for Extending Harness of Tow Ready Magnetic Tow Lights # 73864
    The wiring of the Tow Ready magnetic tow lighting kit part # 73864 is 16 gauge so using 16 gauge or heavier would work well. The best method for splicing would be soldering with heat shrink over the splice.

  • Recommended Lights For Signaling With Bikes Blocking Tail Lights On A 2014 Kia Sorento
    Since you're trying to display your braking and turn signals utilizing your 4-pole connector your best bet is to use a simple magnetic tow light like the Tow Ready Magnetic Tow Lights # 73864. Since your 2014 Kia Sorento is a crossover SUV the magnetic lights will be high enough above the bikes to display. These are a very simple install, the lights have magnets to stick to your vehicle's roof and come with a 4-pole connector cable to make installation take less than a minute. We also carry...

  • Recommended Flat Towing Equipment For A 2020 Ford Edge ST

  • Parts Needed to Flat Tow 2016 Cadillac Escalade
    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...

  • Recommended Tail Light Wiring For Flat-Towed 2018 Jeep Cherokee With Bike Rack Blocking Taillights
    The 4-pin on the rear of your 2018 Jeep Cherokee Overland wouldn't have power running to it unless it the vehicle was running so the simplest option would be to just bypass the wiring you installed when you plan on flat-towing your vehicle and hauling your bikes and instead using some magnetic lights instead like the Tow Ready Magnetic Tow Lights - Red Incandescent # 73864 or the Pilot Magnetic Tow Lights # NV-5164 if you would like a wireless connection.

  • Correct Base Plates and Other Parts Needed To Flat Tow a 2013 Mini Roadster
    The correct Blue Ox Base Plate Kit for a 2013 Mini Roadster is part # BX1307. I understand you are hoping to save some cash and make the Blue Ox Base Plate Kit part # BX1303 work but that is really just not feasible as these base plate kits are custom fit to exact vehicles. The mounting flanges are in entirely different spots so I can only imagine the amount of modifications needed would far exceed the value of cutting cost.

  • Parts Needed to Tow a 2013 Kia Optima on a Tow Dolly
    I checked the online manual for your 2013 Kia Optima and didn't see anything about recreational dolly towing, only emergency dolly towing. While the manual didn't give any distance restrictions for dolly towing it is always best to confirm whether it is safe or not with a Kia dealer. If it is okay then you simply need a tow dolly and then some lights. Tow dollies tend to have lights on them but it helps to have some extra lights to make sure people around you can tell what you are doing. For...

  • Parts Needed to Flat Tow a 2014 Chevy Silverado 1500
    A complete flat towing setup consists of base plates, a compatible tow bar, safety cables, tow bar wiring, supplemental braking and, when needed, a high/low adapter. You'll also want to consult the vehicle's owners' manual for any specific instructions to follow to get your vehicle prepared for flat towing. For base plates I recommend using the Demco Classic Base Plate Kit - Fixed Arms # DM9518200, which will give you a durable base plate with a heavy duty powder coating at a nice price...
