Jeff Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this CURT seven-way trailer adapter for towing trailers with LED lights. Now, this'll basically plug into your existing seven-way socket, and it provides a new seven-way socket that's able to recognize LED trailer lights. They use built-in resistors, which'll enable the LED signals from your trailer to be read by your vehicle's computer. And to install this, there's no cutting or splicing required. It's basically just a plug-in.
This is great for use on the vehicles with the trailer lamp out sensors, like the Audi, the Mercedes and the Volkswagen vehicles that have the factory tow package. What this adapter will do is simulate the increased power draw so the vehicle thinks there's incandescent lights on the trailer. Then you won't get the lamp bulb out reading that usually flashes on the dash of those vehicles. You can see it also, right here, has a nice spring-loaded dust cover. This'll help protect the terminals from moisture and debris when the connector is not in use.
Overall length on this from one end to the other is about 12 inches, and you can see it is a flexible cable. But that should do it for the review on this CURT seven-way trailer adapter for towing trailers with LED lights..
Wow. Where do I start. To be short and sweet: We are Reach for the Stars nonprofit in Tucson AZ. We bought a newer trailer for our astronomy events to help youth with mental health issues through the awe of the cosmos. This enclosed trailer was connected to our 2022 Silverado (newer truck) after a long delivery transfer (1000+ miles), and nothing worked. No lights, no charge, no electronic brakes, warnings were flashing all over. How can a newer trailer on a newer truck not work??! We were so worried about the return fees, delivery fees and issues that we would have to go through if we chose to repair it to save money. After 5 days of research and troubleshooting, we found one single device that seemed like it may be the fix. The LED trailer adapter. What?! The dealer had no idea what was wrong or what would fix it. Never heard of the issue before... Really?Yet, E.Trailer knew what to do. We bought the $20 part on a hope and a prayer, and it arrived quickly, just 2.5 days later. We connected it, and it was an instant success! Everything worked like new. Everything. This little part, which no one knew about besides etrailer, saved our little mission so much money, stress and headache. Thank you for helping us help others to reach for the stars! Now, we just need some nice enclosed trailer locks to protect our gear! Back to fundraising! etrailer is the place to go when your in need!!!!
Solved all my problems with my older Range Rover not communicating correctly (lights always flashing) with the trailer LEDs.
My Sprinter chassis was not communicating with my towed Jeep Wrangler and the tail lights weren't working. This adapter solved the problem! The only improvement in the Curt adapter would be a way to easily secure this adapter to the trailer hitch.
Works great. Fixed the led light problem on a small trailer. No more fast blinking turn signals
As advertised. Great job by etrailer folks with order updates. Received, shipped, and tracking info. I will definitely use etrailer in the future!

It’s awesome! Lighting module fault on the truck. This cured the problem with boat and fifth wheel trailer with led lighting.
I used this adapter on my 2021 Ford F150 to fix a turn signal fault message that kept flashing on screen when I towed my trailers. The pickup computer didn't recognize the LED lights on my trailer.
Works perfectly.
Excellent customer service and fast shipping.

This converter for LED trailer lights works perfectly on my 2021 Ford F150.
This product does exactly what it supposed to: allows truck computer to recognize LED trailer lights. It’s a bit clunky with the 7 blade receptacle looking like an off the shelf component. The first one l received, the main cable insulation was too short, thus exposing internal wires allowing for potential water infiltration. The replacement was just fine. Great customer service in replacing the original part.
We tow a 2007 airstream with LED tail lights and incandescant marker lights. When we upgraded our tow vehicle to a 2023 Grand Cherokee the tail and marker lights flickered but did not go on. An error message told us to check the trailer connection; but the connection worked with every other vehicle I could find. With this adapter in place, the lights still flicker and go off when turned on initially. However after I send some input (brakes, turn signals, hazard it doesn't seem to matter) everything lights up and works fine. Not perfect but definitely usable.
Curt 53007 solved my issue with random turn signals not working and trailer disconnected dash messages . It also cured the left and right camera image not showing in the dash display when trailer is connected and signal activated. Have a Ford 2023 F-350 and pulling a 5th wheel with LED lights.

Hey Kenneth. I'm glad that it solved so many issues you were experiencing. Has it made towing easier without all the errors showing up?

This adapter did solve my goofy lighting issues and that part works well. The only thing that would have worked better is if it didn't have the bulky mounting bracket with the spring loaded door on it. I did remove them with a cut-off wheel a few months ago and now it's easier to use.
This seems to be a little known issue for new boat trailers and RV's outfitted with LED lighting. This product is a quick fix for late model GMC and Chevy trucks. Due to the low signal on trailers using LED lights the vehicles trailer tow package does not recognize that a trailer is connected to the vehicle. I added this adaptor and it worked perfectly. Camera's work on the truck, running lights, signals and brake lights all work. My GMC dealer is getting calls for this issue daily. This saved me a visit to the dealership and messing around checking grounding etc. Well worth the price and from what my dealership is telling me they will be flying off the shelf!
The product did not resolve my issue - is it possible to return it?
In October 2021, I purchased several packs of LED bulbs from etrailer and replaced the dim OEM incandescent marker lights and turn signal lights on my 2021 Coachmen Freedom Express UltraLite 192RBS travel trailer.
Replacing the bulbs was a piece of cake and took only a few minutes. When all the bulbs were changed out, I hooked up my 2020 Ford F-150 and connected the 7-wire connector. All of the new LED bulbs worked flawlessly as expected.
When I made my next trip in the travel trailer, I starting getting “fault” messages on my Ford F-150’s instrument cluster. These messages were alerting me to a problem with either the turn signals or the trailer lights. The first couple of times this happened, I immediately pulled over and checked all my lights. Everything was good. I hit the “OK” button on my steering wheel and turned off the warning. During my six-hour trip, I received these warning messages numerous times (and never a problem was detected).
I sent etrailer a note a couple of weeks ago asking if they had encountered this problem before. Becky B. quickly let me know that my problem was not unique. She suggested etrailers Curt adapter (item C57003) as a possible solution.
I quickly ordered this adapter, and I used it this past weekend (26 March 2022). The adapter worked great! No more “fault” messages.
Thank you, Becky B., and etrailer!
Solved my trailer light problems that my Jeep Grand Cherokee was having.
Fixed the problem I was having with the LED trailer lights.
This solved my issues! Also, same day fast shipping.

Product works as designed, the only issue is connection we’re not properly tightening and after a few uses I had to open it up and retorque
Fixed the issue with my 2009 GL-550.
Was super bummed when I purchased a new 2018 Flacon 23RB and the trailer dealership couldn't get the lights to work with my GL, even after putting in resisters and couldn't leave the lot with the trailer on the back of the GL, had to a friend's truck. Mercedes didnt have any answers either. So hit Google and found this pig-tail.
Thank you SO much!!
Arrived early and corrected my blinking trailer light issue. Great service!
Allows led trailer lights to work prope rly!
I tried it on a 2007 Land Rover and the trailer lights still pulsed. Didn't work.

Hi Harlan. It sounds like you may have a bad ground. You probably already know this but this adapter is designed to help the complex computer system of luxury vehicles recognize the LED lights on your trailer. Since LED lights draw such a small amount of power, the vehicle's 7-way will not recognize the LEDs on the trailer and that leads to the pulsing. Since you are using the adapter and the lights are still pulsing I recommend to check your ground connections. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. I am certain this will fix your pulsing issue and if it doesn't, please let me know so we can continue troubleshooting. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the light grounds to the main trailer connector ground can help.
awesome, My Sprinter lights up my toad Jeep jl With Leds
It works fine and does the job, HOWEVER, it would work much better for me, if the receptacles were together without a cord between them...
my problem: '11 ML350. trailer LED running lights would only flash (like emergency flashers). All other functions worked find - turn signals, brakes, etc. There were no warning lights/codes, etc displayed on the dash.
This product completely solves this problem - it's a quality built product at a reasonable price. Although the trailer end of the pigtail includes mounting bracket for a permanent installation, I won't go to that extent as I rarely use the trailer. I will most likely just zip tie the pigtail to what ever is convenient to eliminate any flopping around while on the road.

1 yr later - still working great wno issues whatsoever.
Once I figured out what was wrong with my truck, this device is doing exactly what I need it to do. Even without plugging a trailer in, the device gets my truck to think there's a trailer. I purchased a camper that needs the 12v charge and this seems to be the easiest way to get the truck to activate that charge lead.
