Frustrated with trailer electrical issues, and the lack of features on testing units, we desgined and built TEDS PRO.  Over 8 months of R&D has gone into this device.  This is BY FAR the absolute best trailer electrical system testing and diagnostic tool on the market.

How we designed and built it...

We are guys that use trailers daily, and built these around what we need, not some lab doing market research.  We would build a prototype, use it in real situations for a month, then make changes and add features.  The circuit board alone has been through 6 revisions before we got to the final version.  Then, when we finally came out with what we thought was the final prototype, one of the guys mentioned how great it works as his wife was checking the lights as he clicked the switches...then it came to us.  Auto Test mode.  This allows you to test the trailer alone, without help. 

This tester meets or exceeds every situation we have ever needed a device like this for, and we are very proud of it.  They are made right here at our facility in Denver, CO.
