Hi guys. I’d like to buy 7 pin round to 4 pin flat adapter with a built-in electrical resistor for LED lights. Do you have any options or what would you recommend? Thank you in advance.

Hi Pavlo!

What you are looking for is the 7-Way to 4-Way/5-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR. This will work with either a 5-flat or a 4-flat, so you will have one open port when plugging your 4-flat into it, but that's perfectly fine and is pretty normal to have happen.

Out of curiosity, what are you towing and what are you towing it with?
