Expert Reply:

For a 7-way adapter designed for German vehicles towing LED lighted trailer to prevent the bulb out error message we have the part # C57003.

For an adapter that plugs into a 7-way and then provides a 4-way we have the part # C35FR. Since it sounds like your LED kit uses a 4-way the kit you'd want is the # C35FR.
