Looking For 7-Way to 4-Way Adapter For Mercedes-Benz Motorhome With LED License Plate Holder
Updated 04/28/2026 | Published 04/20/2026
Question:
I have a 2014 Itasca Navion IQ with a Mercedes Benz 3500 cab and chassis. I need to relocate the rear license plate to the cargo carrier installed in the rear trailer hitch. The license plate light flashes rapidly when plugged into the 7 way connector . I am using a standard 7-way to 4-way adapter as I do not need lights or turn signals on the cargo rack. The Mercedes manual says that the turn signals on the trailer connector only work with incandescent light bulbs. Do you have a 7-way to 4-way adapter that will allow me to use a license plate holder with LED lights? Thanks

Hey Eugene, thanks for reaching out. Yes, we sure do! For a 7-way to 4-way adapter that will allow you to use an LED license plate holder you can use the following:
- 7-Way to 4-Way/5-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR
This is something we use very commonly on Mercedes-Benz motorhomes towing trailers (or in your case license plate holders) with LED lights. It will prevent the "hyper flashing" as we call it and allow the LED lights to work normally.
What do you usually haul on the rear cargo carrier? Bikes, totes or tools?

I purchased a Moto Tote motorcycle hitch carrier that had LED tail and stop lights. Plugged the 7 way adapter into the factory receptacle and then the 4 wire flat one for the lights into the adapter. Solved the problem. No more warning lights showing on the vehicle's dash. 2020 Ford Ranger.
