I do not disagree with the other posts. I have the ACME dolly with led lights BUT I also purchased a set of magnetic lights for the towed car. It is not hard to run the connecting wire to the four pin connector on the coach. I have never had any problem with them. I will give you a word of advice though----go to Advance Auto and get a couple of rolls of the split plastic conduit to run the wires in. It does help protect the wires from turbulence which will eventually lead to broken wires as well it looks better too.
