Easy light check I found this product while searching for a similar product that I had lost. This replacement is better than the other trailer light tester because it doesn't have to be removed to connect your trailer wiring. The one I lost, probably placed on the bumper of my Jeep when I was connecting my trailer had to be removed and stored to connect the trailer. The replacement stays in place between the tow vehicle and trailer wiring. It allows you to tell, at a glance, if you have a problem in your trailer wiring or vehicle wiring. September 29, 2010
Trailer light tester Excellent device, tells if connections are correct for your trailer and in addition acts as a cover thereby eliminating moisture and dirt from contacts. I use it to stay permanently on my connector. Before hooking to a trailer I can test the car side of the lighting system. I then remove the cover/tester and make connection to the trailer.

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
Be prepared I carry this on my keychain. make it easy to start tracking down lighting problems. July 14, 2014
