awesome! works just as advertised My trailer lights weren’t working.

Bought this to troubleshoot a potential wiring problem with my vehicle (factory installed wiring to a trailer hitch) or the trailer. Plugged it in, listened to the beeps, and found out in less than 1 minute from the driver’s seat that my vehicle wiring was good to go. Worth the price and peace of mind! Great product!

I bought this to troubleshoot the trailer wiring on my truck. Most of the little LED lit testers require a second person and a constant reference to the manual for which little light is supposed to come on and mean what. This tester is loud and audible from the drivers seat. You can troubleshoot without having a second person, or having to train a second person on what to look for. I would definitely recommend this to anyone who needs to test their trailer lights.
