well, the carton ends had been taped back together but not fully closed. the "parts bag" of bolts, washers, etc had burst, spilling its contents inside the larger carton. some of them arrived. but upon inventory, it seems the vast majority were lost. some of "nut plates with wire" arrived intact, more were bent, some were missing. all in all, the package went thru hell & lost many of the smaller parts.

when I called etrailer customer service, Marc C was ALL OVER THIS. he patiently went down the parts list 1 line at a time, noting how many were usable & how many I needed. this was Fri approaching 5pm. when we finished, he said that, barring complications, my replacement parts would ship out Tuesday. in light of the outstanding customer service, I am very likely to continue doing business with etrailer.


Good product. Had a small issue with a ground wire but easily solved.


Do what there supposed too. Tight and hard to pull off Jeep rear steel bumper !


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!


As always, the merchandise was received promptly and consistent with my order. Curt products have served me very well over the years---fine design, high quality production and excellent customer service.


Got what I needed quickly

2013 Ford C-Max

Easy to order and quick to arrive. I especially liked the personal touch from an employee who offered me a different item because it was in stock and could be shipped immediately... although I did opt to stick with my original purchase explaining that this was not a Christmas present so I wasn't concerned about the shipping date. The item arrived and I've already checked the system out - it works perfectly - thanks etrailer!!


Excellent; work great. They were delivered quickly.


Purchased a Dolly that from the start was troubled with lights that kept on shorting out spent too much time looking for the exact location of the problem finally said screw it and viola my fix


Poor rating for my application.

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 :).


neatly wrapped in original packaging. looks great, brand new as it should.


Great service and products from etraile r.


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.
Big C - 01/19/2018


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)

1998 Jeep Wrangler

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.


Great customer service. Good product va lue.


Great products fast service


They are perfect. We now have better visibility carrying our bicycle on the back of our vehicle.


They have never failed me!

Ford Ranger

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.


Just got them

2015 Ford Escape

Works perfectly!

Still working great!
Cynthia - 05/10/2021


Lights arrived on time and are going to be just what i need. Easy installation and will serve many aplications. The storage case is a nice idea as well.

2009 Honda Fit

Very easy to use, just plug and play. No wire splicing or complicated connections.

2015 Jeep Cherokee

Has strong magnets, no problems with the operation, quick and inexpensive way to install tail lights

  • Can 2016 Ford Fiesta Be Flat Towed Behind a Motorhome
    According to the information I found in the owner's manual for the 2016 Fiesta, the vehicle can indeed be flat towed. You'll want to look over the procedures outlined on page 152 of the owner's manual, and follow them exactly. The procedures vary according to the transmission that the vehicle is equipped with. I'll link you to some FAQ articles about flat towing, I hope you'll find them helpful.

  • Will Tow Ready Tow Light Kit Fit At Top Of Rear Hatch On 2015 Subaru Outback Being Towed
    The Tow Ready Magnetic Tow Lights - Red Incandescent - 4-Way Flat Connector - 20' Long Harness Item # 73864 should work well for you. The Tow Ready lights should securely attach to the top of your car with the strong magnents. This would put the lights above the bikes you are carrying as you want.

  • Items Needed When Flat Towing Honda Fit
    You will want to check the owner's manual or with a dealership when you consider flat-towing the Honda Fit. Some manufacturers have restrictions as you mentioned for automatic transmissions versus manual transmissions. From my research I found that many people are flat-towing their Fits but the owner's manual from Honda does state the vehicle is not towable. When flat-towing any vehicle there are 5 items you will need. You will need base plates for the vehicle, a tow bar, safety cables,...

  • Where can I attach the Tow Ready Light Kit
    I went to the warehouse and pulled the Tow Ready Tow Light Kit, # 73864. It can be placed anywhere that there is metal. It attaches securely with a strong magnent. You can place it anywhere so that it can be seen from the back. A good place is the top of the towed vehicle. This kit will keep the tow vehicle and toad wiring separate, and provide stop turn and tail lights for towing your VW.

  • Where to Find Out if a Vehicle Can Be Flat Towed
    The best place to find out if your 2014 Honda Fit with an automatic transmission can be flat towed is to consult the owners manual of the vehicle. There should be a section on towing that will discuss whether or not your vehicle can be flat towed and if there are any restrictions. From the research I did it looks like the vehicle is not flat-towable. I attached a couple FAQs on flat towing for you to check out also.

  • 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.

  • Are Additional Lights Required on Towed Vehicle When Using a Tow Dolly
    Generally you don't need additional lighting when using a tow dolly that already has lights. However, it's not a bad idea to check with the local laws in the states you'll be traveling in and in Canada. Some people like to add additional lights just to make it easier to see the vehicle that's on the dolly. If you wish to add lights you'll need to splice in a tow light kit, like # 73864, because the trailer connector on the back of your RV will already be in use with the dolly. Unless...

  • Light Kit Recommendation for a 4 Bike Platform Rack
    I have a solution that would be your easiest option but we don't carry bike rack lighting kits as in most cases bike racks do not block the taillights of a vehicle since they are usually set out wider than the bikes on the rack. The Tow Ready Magnetic Tow Lights - Red Incandescent - 4-Way Flat Connector - 20' Long Harness Item # 73864 would be an option that would be pretty easy to make work.

  • Is Equipment For Flat Towing Vehicle Behind an RV Vehicle Specific
    The short answer is some of the equipment is, some isn't. Typically, to flat tow a vehicle you'd need the following: Base Plate Kit- certainly vehicle specific. Tow Bar- not vehicle specific Safety Cables- not vehicle specific Wiring Solution- Some vehicle specific plug and play options available, many universal or semi-universal options. Supplemental Braking System- not vehicle specific, although there are some tailored for motorhomes with air brakes. The wiring and braking kits will...

  • Magnetic Tow Lights Stay on When Connected to 4-Pole Connector on Tow Vehicle
    It sounds like you have already been doing some troubleshooting which helps to narrow down the possibilities for us. What I recommend doing is testing both sets of lights with another vehicle. Even though it is unlikely that 2 sets of magnetic lights would be malfunctioning the exact same way at the same time, it is not impossible. You can verify that the lights are working properly by performing this test. If they need to be replaced we have the Tow Ready Magnetic Tow Lights # 73864 which...

  • Does Tow Dolly Lighting Need to be Used if Towed Vehicle has Tow Bar Lighting
    If the vehicle on the tow dolly has a set of tow lights like the # 73864 that you referenced and they are clearly visible you could run just them and not also the dolly lights. It's not required that you run both as long as one set is clearly able to be seen.

  • 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...

  • Only One Brake Light is Working with the Tow Ready Magnetic Tow Light Kit
    You will want to verify that both brake light signals are working at the RV side trailer connector. Unplug the Tow Ready Magnetic Tow Lights #73864, and use a circuit tester such as # PTW2992 to test the pins on the 4-Way while someone sits in the RV and runs through the lighting functions. The most likely cause of this is a bad ground or dirt/corrosion in the trailer connector on the RV. It would take a very small wire brush or small screwdriver to clean on the 4-Way.
