Great tester
Awesome trailer light tester. Saves time and makes diagnostics on trailer wiring much simpler. Good quality made product. Will have to supply your own battery.

Fantastic portable trailer light tester
I bought a battery per instructions and it works great. Easy to use. Even actuates electric brakes. I used it to test my enclosed trailer turn signals. So I replace both and they now test perfect. Even tests the 12V from vehicle to trailer, it lights up the break away controller battery charger on the trailer. Well worth the money.

Good but expensive
Overall, it's a good product and does what it is supposed to do. I did put together an 7-way extension cord so I didn't have to run back-and-forth to the front of the trailer when checking the electric brakes. I would've given the product five stars if it came with a remote function.

Game-Changer for Trailer Wiring – Durable, Versatile, and Incredibly Convenient
This tester is a fantastic addition to my trailer wiring toolset—honestly, I wish I had discovered it years ago. I've already used it to repair or install lighting on three different trailers, and it has made the process dramatically easier. No more needing to hook up a vehicle just to troubleshoot or test connections. The build quality is top-notch—you can immediately tell it’s made in the USA. The connectors cover virtually every trailer wiring plug configuration, and the added sound feature for turn signal testing is a great touch. This tool is a huge time-saver and incredibly convenient. Without a doubt, it’ll get a lot of use in my shop.

Money well spent
I work in a shop where diagnosing trailer lights and electric brakes are a daily occurrence. This box has made it extremely easy to do trailer electrical work. Strongly recommend for anybody doing a lot of trailer work.

One of the best tools I have
Great tool to have if you own or repair lights on trailers frequently. So much better than a test light and blowing fuses on the truck. Annoying that the battery doesn’t come with it but not a big deal
