A Time-saver! This simple little tool works great and is an amazing time-saver to help diagnose your trailer light hook-up functioning on your vehicle. I got this before I got a trailer to make sure my tow vehicle's tow package was still working great! These are next to impossible to find locally. This was a bargain! Highly Recommend!

Note, that I could NOT get my tester to show Right Turn, Left Turn, and Running Lights, AT THE SAME TIME.When I did them all separately, they would work great. Took me a while to figure that out, wasting some time in the process.

Didn't register signals effectively, connection was intermittent and unreliable... exactly the worst thing for a test tool.

This tests all connections in a 7 way round trailer plug. It is easy and quick to use. Just plug it in and turn on all tow vehicle lights and other functions that connect to the 7 way female receptacle. I particularly like that the led indicator lights are bright enough to be seen in bright sunlight. I would recommend this product.
