A pair of new Lite-Check testers will conveniently test trailer lights and electrical systems. The Pro-Check 720 and 720AC can be operated with a simple control panel or remote control.

Software allows the Pro-Check to identify and monitor electrical faults in the same fashion as Lite-Check's Inspector trailer testers.

The system allows for a DOT-style inspection by a single technician in just a few minutes. The 720 is designed for 12-volt DC trailers using a 7-way connector.
