Video Transcript for Review of TowSmart Custom Fit Vehicle Wiring - Wiring Adapters - TS57RR

Hi, everyone. Steven here with etrailer.com. Today we're looking at our TowSmart Trailer Connector Adapter with LED Illuminator. It's gonna be a 7-wire to 4-wire flat adapter. So, folks, just like I said, you're gonna be able to convert your 7-way or 7-blade back to a 4-flat connector. Now, this is a plug-and-play design, no cutting or splicing required.

It's gonna fit snugly without dangling wires. This is weather-resistant heavy-duty plastic. It protects against moisture and road grime and when it's installed it's gonna support tail lights, brake lights, and turn signals. Now as I mentioned before, this has a built-in LED illuminator. It's gonna illuminate this whenever you have it plugged in and the vehicle is running with normal running lights.

So I do have a test box here, gimme a second, and this will help simulate this being plugged in to a trailer. And then once I give power to it, such as, you know, running lights, now you can see it is illuminated. So, again, it illuminates just like that. Let's go ahead and shut off the overhead lights real quick so you can kind of see how bright it is in the dark. So, again, it lights up pretty nice.

And we'll turn the lights back on, and shut it off. So again, that nice feature with the LED is going to make it to where you know that you're getting power back to the unit and make you a little bit more visible at night as well. That's gonna wrap it up, folks. I'm Steven. Thanks for watching.

Had to bend all the pin-tabs in the adapter to get it to fit any of my 3 trucks.
Rubber seal on the flat pin seems very good & water tight.
My suggestion to the mfg. would be to add the test lights as on other non-colored brands.
