Rated 5 out of 5 by Trailer Light Tester The wiring and lights on a trailer always seem to not work when you get ready to use them. This little tester helps to narrow down the problem. March 29, 2011
Rated 1 out of 5 by Useless - DOA My trailer LED's work fine but no response from this once attached. Not a flicker not a sign. I can only think it's DOA. Useless. A tale of great expectations that wasn't to be. Wish I could be more helpful with this review. November 23, 2010
