When I put the tow hitch on my Volvo, I bought a separate light controller for the trailer lights. It plugs into the car's factory wiring harness for the taillights, so no cutting or splicing wires, and has an independent power connection. It doesn't appreciably change the load on the car's lighting, so the "bulb-out" nannies are happy, and it handles LED or incandescent trailers fine as it's just supplying 12v signals. Mine has a 4-pin flat connector for the trailer.
