I continually had issues with my trailer lights. It probably wasn't six months I started having to work on my trailer lights on a new trailer. It seemed like 99% of all my problems seemed to involve a ground wire connection to the trailer frame.
Back in July of 2009 I had LED lights put on my trailer. I also had them completely rewire the trailer and had them add a third ground wire to connect to each light just as the hot wires did. I also ask them to have plenty of extra wire length tucked in at each light so that it would be easier for me to replace or repair any of the lights if needed.
Its been three years and I have not had one issue with my trailer lights since putting new LED lights and wiring on my trailer. Knock on some wood here. I really think the third ground wire is what really helped here but with my LED lights I never unplug them while launching or loading out the boat.
As you can probably tell I just love those LED lights and all I can say is go for it and you'll love it also. I still haven't found out if they were generous in leaving plenty or wire tucked in at each light. I am sure I will be finding out one of these day but so far so good.
