Designed for use with vehicles that have lamp-out sensors, this adapter ensures that your trailer with LED lights does not trigger any warnings or hyperflashing when hooked up to your vehicle's 7-way, blade-style connector.


Features:

  • Bypasses your vehicle's lamp-out sensor so that you can tow a trailer with LED lights
    • Prevents your vehicle's computer from sensing that a trailer light is burned out, which is how it would normally read the LED lights on the trailer
  • Designed for use with vehicles with Lamp-Out sensors - such as Audi, Mercedes-Benz, Volkswagen, and Porsche
  • Plugs into the 7-way, RV-style trailer connector on your vehicle
  • Provides a new 7-way, RV-style trailer connector that works with trailers that have LED lights


If you have a vehicle with a factory tow package that has a lamp-out sensor and you tow a trailer that has LED lights on it, then you've likely experienced hyperflashing and/or false computer errors. Because LEDs pull such a small amount of power, certain sensors are unable to detect them. The result is a warning in your vehicle that continuously tells you that the trailer lights are not functioning. In addition, the lights on your trailer may not illuminate properly because of your vehicle's inability to recognize LED lights. This can lead to either hyperflashing lights on the trailer or lights that will not illuminate at all.


This adapter has a built-in bypass system that is designed to eliminate these problems. Just plug the adapter into your vehicle's 7-way, RV-style trailer connector and you're good to go. Plug the wiring connector from your LED-lit trailer into the adapter's 7-way, blade-style receptacle and the trailer's lights will illuminate as they're supposed to, without triggering errors in your car's computer.

This adapter saved our sanity! Our 2019 F350 kept giving us the ‘trailer disconnected’ warning constantly while pulling our fifth wheel. We researched the problem online and realized that our truck wasn’t sensing the led lights due to their low voltage. Took the truck to the dealer who assured me they could fix it however the first time we took it out and I adjusted the trailer brakes I started getting the message again . So tried finding an adapter to bypass the bulb out sensor on the truck. I found this via a google search . Plugged this in, and no issues since!! It is awesome and such a good price! I would recommend this to anyone who is towing a trailer with led lights with a Ford truck.

Still couldn’t pull my trailer without it , I just wished it would fit tighter. I have to wrap short bungees around it to keep it tight.

This solved the problem between my 10 year old SUV and my external brake controller. I would lose connection between the two and have constant failures - sometimes while driving. Needed to add some fastening (a mini bungee cord) to keep it connected tightly but has worked like a charm. No failures and a full season on the road.

Solid, Well-Made, Does Exactly What It Should. HyperFlashing is Not Cool!!! I've been trying to track down a part which solves this problem for a while. I started using an LED-equipped trailer and the hyperflashing & computer warning messages are annoying! I almost settled for 20141, but glad I waited. Also, most retailers aren't receiving this part for another month or more. eTrailer shipped the same day as my order. NOTE: This works well with Range Rover also. Not related to the product: This was my first eTrailer order and I was VERY impressed. I spoke with two ladies regarding this part and eTrailer's customer service is TOP NOTCH. I will definitely order again in the future! THANKS!

what year range rover does this work with. I just tried it on my 2008 LR3 and I still have the problem?
-- comment by: Art M - 07/18/2013

It should work independent of year. Check your trailer connector and make sure the connections inside have not corroded for starters. Also check all the grounds of the trailer wiring and if applicable on the vehicle trailer connector. Ground issues cause most of the electrical gremlins in the trailer world. On 7-Way systems, corrosion inside the connector is another likely culprit.

I am an amateur Porsche Race Car Driver and have a trailer that I pull my race car on. I pull my race car with a Porsche Cayenne Turbo S. I could never get the lights to work properly and hated to rewire as I use an american truck sometimes. Before installing the adapter, the lights would just blink and had no brake lights or signal lights.. The adapter I bought is a great solution for European cars and/or trucks. I purchased the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End and it works perfectly. The blinkers works. The brake lights work. I can't believe such an inexpensive solution solved my problem. Contact e-trailer before you think of rewiring any trailer.

I bought this to try to override the glitch in my 2019 GMC 1500 Denali that would not allow the Furrion RV camera to connect. Some on Forums claimed that this was the fix... It didn’t solve the issue. Thankfully that issue went away when I traded for a 2020 Denali HD 2500. Nothing wrong with the product, it just wasn’t the elusive silver bullet I needed.

This lamp out sensor adapter did not work as I’d hoped, did not defend GMs PWM software allowing camera & LED lights to function. Had to purchase a Furrion bypass pigtail specifically made for this. However made use on a utility trailer as extension & adapter. So yes, happy ending and was happy with product. Five stars

Great so far -- bought this to connect a Mercedes ML350 suv to a Flagstaff travel trailer. As is mentioned many times in different trailering forums, some European vehicles have an issue with false sensor readings when connected to a trailer with LEDs. I had the same exact issue and this adapter seems to have fixed the problem perfectly. Time will tell as we go on our first big road trip with the travel trailer next week. But for now, looks like a winner.


Comments
Adapt or works fine. Using it on a Mercedes ml350. However, we bought it ruse with a Curt Bluetooth brake controller which is a piece of junk so we don’t really use the adaptor any longer at this point.

I purchased this product in order to try and correct a problem between my 2020 GMC Sierra and my 2 trailers, both which are new and completely LED only trailers. I have turn signals, brake lights, and hazard lights, no tail/running lights. This product is fine, shipped fast, etc. however, it didn’t correct the problem I’m having.

Worked perfectly for my 2017 GLS550. One thing to note. I had a hitch put on by the Mercedes-Benz dealer so this wasn't an aftermarket hitch and harness. I had trouble even after purchasing this adapter, but it wasn't the adapter that was the problem. It was the fact that the trailer module that sends the signals can be programmed into two different modes. One for EU trailers and the other for US trailers. This manifests it's symptoms as ever light works (turn, running, flashers) BUT the Brake. In EU configurations, EU trailers use a completely separate wire to light the brake lights up. In the US, it's both of the turn. So, after purchasing several different adapters like this one (which I still like and kept), and three different trailers doing the exact same thing, the dealer had me bring in my vehicle and my trailer to troubleshoot. After about 30 minutes and a reprogram, trailer brake lights worked flawlessly.

My tow vehicle is a Mercedes 2006 ML500 that had issues connecting with the improved LED lighting on my Airstream trailer. I had a choice of a $800 wiring upgrade or this; I tried this and couldn't be happier. Highly recommend to solve the problem - works well, sits in glove box, has held up to frequent use. Only comment - you have to be more firm when you insert It into the receptor - not a big deal, but a thought if you're having problems connecting. Great product, customer service - this company provides practical and reasonable solutions. I'm a committed customer.

The product does not work on Mercedes Benz vehicles that have led lights. It was suppose to resolve my voltage difference between the led lights (8-9 volts) and the rear view camera that requires 12 volts. That never happened. I rewired camera to run off interior lights instead of using device



- 20142
by:

I have to rate the product in the middle. I was told if I bought this product it would reduce drop outs of signal from my rear view camera on my 5th wheel. It had no effect at all. I was told that since the 5th wheel had all LED lights running at lower voltage, the lower voltage is what was causing my camera signal to drop. I should have known better.

Bought this to use on a 2017 Ford F350 that was having trouble with trailer turn signal fault and trailer disconnected message would also come up on the dash. Finally figured out it was the LED lights on the trailer that were causing trouble with the trailer system on the truck. This adapter works great for that , even though it doesn't list it as working with a Ford. Very good product and very good service!

Thanks for the Review Mike. I did reach out to my friends at Tow-Ready and confirmed that this item is not exclusively for the European vehicles, and will work with any vehicle that has a trailer lamp out detection monitoring system. The European models were leading the way with those electrical systems. Also if you happen to need a 7 to 4-way adapter the # TR20141

functions the same way. It just provides a 4-way for the trailer connector.

It is kind of like spinach. A great addition to your vitamin intake, however it tastes horrible. So goes this plug. It does the job well enough and seems to work well, the cost is good, but the damn thing won't last. The door that is spring loaded is so lightly manufactured it will break. How do I know this? This plug is my second plug of the same style.

Got my LED trailer lights work in on my Audi! I had a small issue with the spring hinge, which broke on the first unit.

Excellent customer service, and they promptly addressed my minor issue with the first product.

Product works, but flip top design is flawed and easily pops out of its spring position, preventing the top from locking in the trailer connector. This presents the poor situation that the trailer connector will vibrate out and you would lose trailer lights/brakes going down the road. Simple design fix would be a better placed and stronger spring for the top. Only solution with the current design is to push the spring back behind the swivel point to create adequate pressure or tie wrap it in place. Constant worry issue for this single weak point on the otherwise well made item.

This product is a lifesaver! I have a 2014 Range Rover and I just purchased a new trailer and for the life of me, the dealership, and the trailer manufacturer, we could not figure out why the electrical on the trailer would not work when plugged into the car. The trailer manufacturer confirmed the lights worked on the trailer, the dealership confirmed electric was going to the 7 pin connector on the hitch but for some reason the lights/brakes/etc would not work on the trailer. After doing some research on forums online, I was able to find out that the newer high end cars do not recognize the low power draw of LED lights on the newer trailers. This attachment is simple to use and created enough resistance for the vehicle to recognize the connection and is just a simple plug and play. Could not be happier.
