1997 Nissan Pickup

This kit did the job very well. I could have bought each part separately and saved some money, but I went with the comfort knowing all these parts will work together to accomplish the job. I couldn't figure what LED bulb to use for both brake and turn signal. I routed the wire along the truck wiring harness for half the way to the front, then slipped it into the frame channel for the rest of the way. I used a Curt heavy, round 4 pin plug at the front grill. It was a bit of work and took many hours but came out clean!

We took the toad on a 4200 mile trip out West and back. The lights worked perfectly and look nice and bright too!

@DiyB That's great to hear!


I installed this on our 2019 Equinox towed. Love the convenience of just plugging in the towed vehicle. The most difficult part was deciding on what part of the light housing to drill the hole for the light socket.


Loved the product, easy to install and have showed off many times while we wintered in Texas. I would have loved to take the credit for idea but was happy to let them know where I bought from.



No issues. Still looking like it’s newly installed


Great product. Bulbs were a bit bigger than I had expected but they worked fine.



We had one bulb quit working after a few weeks. I called Roadmaster after diagnosing it and since it was so soon after install they sent a replacement. We were on the road when I noticed it failed I stuck an old 1157 bulb in so I was legal. Being a retired mechanic, I know that a certain percentage of new parts are defective and what makes the difference is how the comapny stands behind their products. I couldnt be more impressed with both eTrailer and Roadmaster. It was also nice that the temporary fix so I could continue my trip was easy and inexpensive. After replacing the bulb the upgrade has continued to work without a problem.

2008 Jeep Liberty

I wanted a tail light system that would operate off of my motorhome, but didn't tie into my towed vehicles wiring. This kit did the trick! Led bulbs are super bright! Kit has everything you need for a smooth install.



Still working great. Nice bright lights

GMC Yukon

Easy install just like the tutorial video showed!

I used a step drill from Harbor freight. Allow the bit to do the cutting and it didn't crack my housing.

The hardest part was deciding how to route my cables. Came with enough wire to mount in my GMC Yukon.


I have had these lights installed for over a year. I tow a Kia Nero on a tow dolly with my motorhome. Even though the dolly has tail lights, I wanted my car to have tail and brake lights as well. I installed these lights inside the Kia taillight assembly and spliced them into the dolly wiring harness. The lights work great, very bright. The hardest part was figuring out how to install them inside the taillight assembly since they were not made for the Nero. There was no Nero kit available.


The kit should have come with a means to land the wires at the front of the 'toad'. A male connector at the very least.
I should have done more research as the same kit is available in several places for $[XX] as compared to the $[XXX]charged by etrailer.

Thank you for leaving a review and for bringing this to our attention. Here is a link to our lowest price pledge. Our customer service team should be reaching out to you in the near future.

2019 GMC Canyon

I purchased this taillight option because didn't want to go to the expense of the wiring kit with the diodes, etc. Since I have to disconnect the battery in this vehicle for towing, I needed to use the power from the motorhome trailer plug. I followed the directions and video and the kit was installed as they depicted and it works great. The LED lights are very bright and light up the top half of the taillight assemble which is more than ample.

2014 GMC Sierra

Installed LED tail light wiring kit (Brake, Tail & Signal) in 2014 GMC Sierra taillights. For towing behind motor home. LED lights are brighter than incandescent. Installation instructions easy to follow.


These lights are BRIGHT! Easy install. I needed about 10 more feet of 4-strand wire, however. Ended up having to splice some together.

Jim H.


Tail light LED sockets are bright but leak water and condensation in my tail light assembly.


Very happy with the with the LED Bulb and socket set. A great install job by etrailer, and without messing with the towed vehicles wiring system. Wish this had been around years ago! Stellar,a five star product


The roadmaster tail light kit is an easy DIY kit that comes with all I needed for install on 2012 Chev Colorado . The hardest part was trying to crawl under the truck to run the wires. The lights are seperate from the Colorado and are very bright.


looks well made will try to install it tommorrow, I like the LED bulbs =, only wish Roadmaster would have included a 4 pole pagtail to plug the finished install into my motorhome. I will need to visit a autp parts store tommorrow for that piece.

2009 Honda CR-V

Not enough wiring! I am about 3 feet short with the brown and white wires. Now I have to stop, go and buy more wire to finish the job. This is on a Honda CRV.

Thank you for the review and for bringing this to our attention. Our customer service team should be reaching out to you in the near future.


So glad I got this kit! Running the wires from front to back was the hardest part. I really liked not splicing into my existing factory lighting wiring.


Great kit. Had to route the wiring in a protective location. Drilling the housing was easy. Good product. Installed a yr ago. No issues. Would buy again.

Dan S.


Sweet trouble free kit, Wiring too short for a long bed pickup. Soldered and added a 3 extension & works great. Troublefree.

2005 Mini Cooper

I bought separate LED lights for the brakes light and turn signals of the towed car. I also have a braking system attached to the car that will press on the brake of the car. Question - will the car brake light and the led brake light both come on at the same time and is this a problem.?

Thanks for your help

2014 GMC Sierra

Installation was straight forward, and in my situation easy. I have used every system on the market and this system is by far the best if it will fit in your lens. I installed it on a 2014 GMC Sierra which requires the ground cable to be removed when towing, so in my case grounding to the truck was useless - just use the ground from the tow vehicle. Also a 7/8 hole saw works better than the 1" that is called far.

2018 Chevrolet Malibu

This product had a great etrailer installation video specifically for my car. the only problem was that there was not enough wire! I had to go to O'Reilly's to buy more wire.

1989 Jeep Cherokee

Easy to install and no exposed wiring. Make sure you have room in the back of your tail lights for the socket assembly - I should have checked first because I had not a lot of room to work with but in the end they fit just fine.

2018 Chevrolet Spark

I have always had great customer service with etrailer. Spent a lot of money. I bought the complete towing package for my 2018 Chevy Spark. Everything looks great.

Chevrolet Spark

Wired a 2021 Chevrolet Spark. Good videos availability for help with installation. Several possible methods to route wire from front to back.


Just arrived here. Opened the box and liked all needed materials are supplied. Plan to install next weekend.


As always the service and delivery was what we have received from the first order years ago up to the latest.
Pricing has always been right, why would we look any other place than ETrailer.

    If you're wanting to install a bulb and socket kit like the Roadmaster Tail Light Wiring Kit for Towed Vehicles # RM-152-LED to bypass your vehicle's wiring you could. The bulbs in this kit are designed to be placed in your tail light housing next to your vehicle's bulbs and the wiring run to the 6-wire port at the front of your vehicle to connect to your RV with.

  • Is There a Specific Location to Install the Wiring Kit # RM-152-LED on a 2017 GMC Sierra 1500
    The 1" hole for the Roadmaster Tail Light Wiring Kit # RM-152-LED isn't actually very specific. Just as long as you have enough room for the LED bulb. I wish I could be a little more specific but we have never installed this kit on a 2017 GMC Sierra 1500 ourselves (as of Sept 2018) so we don't have an exact video to reference and the installation instructions are very generic. I have linked installation videos on a 2016 GMC Terrain and a 2003 Toyota Tacoma so you can get an idea of where...

  • Will Roadmaster LED Tail Light Bulb and Socket Wiring Kit Work with Incandescent Bulbs on an RV
    Yes, but, your RV likely has a trailer connector on it already and that connector is not tied into the RV tail light wiring so it would not affect Roadmaster Tail Light Wiring Kit for Towed Vehicles - LED Bulb and Socket - Red Item # RM-152-LED. Even if the RV did have a connector that was spliced into the tail light wiring on the RV this kit would still work for you! I have included a link to a video showing an example installation on a 2017 Chevy Spark.

  • What Color Are the LEDs That Come With the Roadmaster Tail Light Wiring Kit for Towed Vehicles
    The Roadmaster Tail Light Wiring Kit for Towed Vehicles part # RM-152-LED comes with red LEDs which are needed because with LEDs you must use a bulb color that matches that of the tail light housing in order to get a true color. The bulb type that is used is indeed an 1157 so there would be different intensities based on if the stop or tail lights were activated. Please note, the Replacement LED Bulbs and Sockets part # RM-152-2 are just the replacement LEDs for the Roadmaster Tail Light...

    At this time we do not currently have a video of the installation process of the Roadmaster # RM-152-LED kit on a 2017 Ford F-350, but as soon as we do get an opportunity to make one we will certainly be looking to take advantage. To install a Roadmaster Bulb kit like the # RM-152-LED you'll need to remove the tail light housing on your vehicle and just choose the best spot for a 1" hole to be drilled without interfering with any of the other lights or wiring components. You could potentially...

  • LED Bulb & Socket Tow Bar Wiring Compatibility With 2020 Ram 2500
    When wiring in the Roadmaster Tail Light Wiring Kit w/ 7-Way to 6-Wire Connector - LED Bulb and Socket - Red Item # RM-152-LED-7 you'll want to place the bulbs in the red portion of the tail lights. Without seeing your tail light assembly fully taken apart to know where you'll have enough clearance in the red portion of the lights it's hard to say a specific spot will work. The LED bulb is going to stick into the light assembly 2" so as long as you have that amount of space it should be fine.

  • Tow Bar Lighting Recommendation for 2014 Honda CR-V
    For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV. I attached an install video for this on a similar 2014 Honda CR-V for you to check out as well.

    If you're looking for a kit to light the side marker lights while flat towing then no, there is not currently any kits made for this purpose.

If you're just wanting to replace the side marker lights with something brighter then there are kits available,...

  • Is Brake Lite Relay Needed When Installing Bulb and Socket Kit on 2009 Ford Escape Hybrid
    Yes, since your braking system presses the brake pedal of your 2009 Ford Escape and the brake lights come one with the ignition off you need to use a brake lite relay part # RM-88400 so that the LED bulb and socket kit part # RM-152-LED turn signals will still work when the brakes are applied.

  • Solution for Airstream with LED Taillights With Issues Using Tow Bar Lighting
    It's probably something with the trailer wiring of the Airstream. I am guessing you maybe have the trailer harness ran directly to the taillight circuits which since they are no LED aren't working well due to amperage draw differences. If this is the case a wiring harness like the part # C59496 would take care of the problem since it would draw the power for the trailer taillight from the vehicle battery instead.

    I did take a look at the tail lights that come on the Ford F-250 King Ranch edition and I can see what you're referring to with the LED lights. When installing the Roadmaster Tail Light Wiring Kit # RM-152-LED-7 you need enough space to drill a 1" diameter hole in each of the tail light housings.
