The 7-Way to 7-Way adapter, # C57003, is designed to work on German vehicles like the VWs, Audis, and so on to deal with a bulb-out sensor issue present on those vehicles. It may not work the same for other applications like on your Land Rover.

If the LED lights on the trailer are not providing enough power draw on the system you can try installing some load resistors on each of the lighting circuits (right turn/brake lights, left turn/brake lights) behind the trailer connector. You would need # P230004A-2. These should provide enough power draw for the vehicle to recognize the trailer.

This is from the website - my vehicle is old, so I don't have this issue.

Get that part and you will be fine. It happens to all European vehicles when connected to a trailer with LED lights. There is nothing wrong with your vehicle. Not a big deal.
