Dunarri TEDS Pro – Trailer Light & Electrical Tester

Trusted by US Coast Guard, Fleet Services & RV Techs Nationwide

The TEDS Pro is the ultimate trailer light tester and wiring diagnostic tool. Designed for RVs, commercial trailers, and pickups.

The TEDS Pro is the most advanced trailer light tester and electrical system diagnostic tool on the market.

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.
