It worked well for me

The installation was easy once I had removed the old lights and wiring. I am pleased with my purchase and would purchase this item again if I ever have the need to rewire another boat trailer.

So happy!

I was very excited that the wiring was long enough to get my boat re-wired and it didn't take long at all. Thanks!
