I order Blue ox base plate bracket kit BX 88230 and light kit RM-155 for my 1995 jeep so I can tow it with my motor home price was great shipping was
Quick . They were easy to install and made of good quality .The kits had
great instructions I am very happy with purchase William in CA.
Easy install, work great! Wire connectors could be better.
It was an easy installation but I did have one issue with cutting the hole in one taillight. I did not measure quite exactly and clipped a support (plastic) in the taillight. This left the seating of the new bulb a little off but it worked fine.
I have since sold the vehicle and when I purchased new wiring for the replacement vehicle, decided to go with the diodes as I did not like cutting into the taillight.
That installation went well with no issues.
Wiring kit was easy to install with video instructions from YouTube.
Have pulled car several times with no problems and all lights work as advertised.
Installed this type of wiring system kit because I did not want to modify the vehicle electrical system due to the extensive computer system within the car.
I ordered a Bulb and Socket kit for my 2019 Chevy Equinox. I’m getting ready to install it this weekend. I am disappointed in a couple of things so far. The kit was clearly a return from another customer. The packaging was cut open and taped closed, and the inside bag of small parts was also cut open and stapled. I don’t know if something was defective. So that is concerning.
Also odd is that the online instructions refer to using “the self-tapping screw” for a ground, but it’s not included. Had I known, I could have ordered it with the baseplate and kit, but too late now. Why not include it?
The online instructions and video depict and give instructions for wiring the harness to the 6way plug, again, not included. This kit included some rather flimsy flat 4way plugs on the wiring harness. I will need to cut those off and order a 6 way receptacle. Again, had I known ... since shipping is included only with orders of $100, not excited to find I need small extra parts, that I now have to get elsewhere, and quickly.
So hopefully the install will go well. I like the videos.
Good materials and instructions. There is a YouTube video that is very helpful. I would have liked a longer connector that goes between the motor coach and the towed vehicle.

Still working great!
I purchased this wiring kit for use in my 1999 Mazda Miata.
I did not want to cut into the OEM wiring harness, even using the diode method to safeguard the system. I felt that the fully separate wiring harness was more to my way of thinking for getting my car ready to tow.
I did not follow the included instructions that said to run the flat 4 wiring beneath the car, zip tying it along the way free of the exhaust and moving parts. I ran it through the firewall, beneath the dash, under the center console, and under the carpeting back into the trunk area. I then installed the bulb holders as instructed in my OEM Miata taillight fixtures.
I am happy to have all the wiring up and out of the way of potential road hazard damage, as well as the hot and/or moving parts beneath the car.
It works perfectly, and I am glad that I purchased this kit, and also that I decided to install it the way I felt best to do so.
It took much longer my way, but I'll never have to mess with it again.
I really didn't want to install a separate bulb kit but our Equinox light was not compatible with our motor home. I was also installing a trailer lighting harness for the Equinox at the same time and doing them together made a lot of sense. I found this kit to be easy to manage and that drilling into the rear light housings not nearly as difficult as I had imagined. I would share a picture of the result but fortunately there is nothing to see - everything fit right into the Equinox's rear lamp structure. I compared the original lights with those from the kit driven by the RV and found them to be a great match. I upgraded the kit bulbs to LEDs for greater longevity.
The supplied wire should be slightly longer. I could not do a small Honda crv without splicing in some additional wire. I recently did a GMC Envoy XUV. And had to purchase additional wire.
Nice to not have to splice into vehicle wiring harness. Separate bulb assembly in existing tail light housing works great for towing our "TOAD" behind motor home.

Still works great after a year of towing to many destinations.
Great product, not a bad install and works great. I chose to cut off both 4 flat connectors and I installed a 4 round connector with spring cover on the front of my CRV. Looks and work out great.

Still working fine.
Good instructions. Everything need is included for 4flat connections. One bulb socket arrived with the ground (black) wire loose in the bag. The solder joint had failed. Resoldered but had to remove the other wires and rubber insert from the bulb socket to avoid melting. Not a shining example for Roadmaster.

no issues, working as expected
This kit really simplifies wiring tail lights on a vehicle that will be towed. No cutting into the vehicle's wiring and adding isolation diodes. Very functional and easy to install.

The parts are working perfectly. Thank you.
Kit was of good quality components. I would recommend about twice a much protective wire wrap along with extra of the smaller butt connectors. Fortunitely I had what I needed on hand. I also used a larger ring terminal.

Works great. 2002 Jeep Wrangler tail lights have plenty of room for the extra tail light bulbs.
A very clever idea for an easy, neat, simple installation to safely operate tail lights on a towed vehicle. We installed this kit on our 2017 Chevy Sonic and it works great.

Thanks for the follow up. Everything is working just fine, no problems, nothing but good performance.
I have used the brake light wiring kit on 2 other towed vehicles. It is an easy install, does not compromise the original factory wiring and works well.

Easy install, working well 1 year later.
Great idea. After years of towing with magnetic lights now all I have to do is plug it in, and I'm done.
The kit kit comes with more parts and wire than I needed and was simple to install on my 2010 JK.

Thanks Patrick. It works so well I forgot I had it.
I like this product and would definitely buy it again. I like not having to splice into the vehicle wiring and install diodes, etc. It is a clean installation with good instructions. All I have to do to hook up the lights is raise the hood of the towed car and pull out the pigtail and hook it to the motorhome. It is powered by the motorhome and does not run down the battery in the towed car. Great product.

Works great! Would definitely recommend it.
I purchased a Blue Ox base plate, Air Force One braking system, and a light kit for my 2013 Durango. I could have not asked for an easier process with selecting and ordering, also the tutorials and videos were a great help in determining what was the best system for me . Everything arrived as planned and in great condition. This is not my first time using etrailer.com and my prior experience was equally good.

After using the items I reviewed, about 6,000 miles, I am more than satisfied. The towing setup is easy to hook up and unhook and the braking system is second to none. All of the installation was completed by myself and a friend, both of us have a technical background him more than me and we found the videos of the installation extremely helpful.Thank you for following up and providing excellent products as well as support services.
Found this item was wired with the brake lights for the brown wires and turn/running lights for colored wires and this fact kept me from getting this done very rapidly. Once identified, went together really nicely and actually grounded to frame for higher light output. I upgraded 3 wire into 2 wire converter with "Roadmaster Brite-lite 3 to 2 Wiring Converter" and they are as bright as the lights already in the housing. Except for that wiring issue, it would have been excellent. As to performance after install, great. Customer service was nice from Roadmaster as well. Did receive a call back message from etrailer a couple days later.

Continues to work as it should! Very pleased with end product after installation by myself and continue to be happy every time I hook up since! Nice item! And customer service...Well they checked back with me a year later to see if I needed anything. How is that for the best customer service around! A
Great product. I installed on 2003 Toyota Tacoma. Since it was a 21 year old truck and I know the wires can get brittle. I did not want to cause any other issue. I decided to go with RM-155. I had enough space to the tail light to drill a hole and insert new bulb. Installation took about an 1 1/2 hours. Running the wires was what took a little bit longer than expected. Hook it up to rv and works flawlessly. I did make slight change. Instead of staying with the 4-pole connector, I hooked it up to a 6-pole connecter and works perfectly. Happy I went this route instead of splicing wires.
This was a good option for our 2020 Chevy Equinox because it does not tie into the tow vehicle electrical system and runs directly from the Motorhome electrical system.

After a year... the light system is still working as specified. A good simple option.

This product was easy to install but it took some time routing the wiring harness from the front bumper to the rear. Pick up some extra zip ties, you will need several. The lighting system is independent allowing for the use of LED bulbs. Great product.
Put this into a 2002 Jeep Liberty. Good directions. Drilled out the lower part of tail light housing and install bulb sockets into it. You may have to deburr the tail light housing a bit and manipulate the tangs on the bulb socket but is fine. I put in 1157 LED bulbs :) Good stuff!
Ordering was easy and shipping was good.
It will be anothere month before it gets installed but the product looks great. sturdy.
All the other parts appear to be as ordered.
Will update when finisher
