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.

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.

Great for inspections or diagnosis to find out which end the problem is!

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.
