What does Lite-Check do?

Lite-Check designs and manufactures advanced trailer inspection, testing, and diagnostic equipment for the trucking and fleet maintenance industry. Our systems help fleets, repair shops, and OEMs quickly test air brakes, lights, ABS, and electrical systems to ensure safety and DOT compliance.

What is the Inspector 930, and how does it work?

The Inspector 930 is Lite-Check’s flagship trailer inspection unit. It provides automated testing for electrical circuits, ABS, and air systems — giving technicians a full DOT inspection report in minutes. The system detects shorts, opens, cross wiring, and other electrical issues, helping reduce downtime and maintenance costs.

What makes Lite-Check products different from other trailer test systems?

Lite-Check products are built for professional fleets and technicians who demand accuracy, durability, and traceable results. Unlike basic testers, Lite-Check equipment offers digital readouts, automatic reporting, and Bluetooth connectivity for real-time results — all backed by decades of experience in trailer diagnostics.

Can Lite-Check equipment help my fleet stay DOT compliant?

Yes. Every Lite-Check system is designed with DOT compliance in mind. Automated inspection reports generated by the Inspector and Pro-Check series provide clear documentation that helps meet federal and state inspection requirements.

What is the Pro-Check system used for?

The Pro-Check system helps technicians quickly test trailer lights and electrical circuits. It displays voltage and amperage readings and identifies faults such as shorts, open circuits, and ground issues—taking the guesswork out of troubleshooting so your team can find problems faster and make repairs with confidence.

Does Lite-Check offer training or technical support?

Yes. Lite-Check provides U.S.-based technical support, training materials, and personalized assistance to help teams get the most from their diagnostic tools. Our experts can walk your technicians through setup, testing, and interpreting reports.

Where can I buy Lite-Check products?

You can purchase directly through Lite-Check.com, by contacting our sales team, or through authorized distributors across North America. We offer bulk pricing and fleet purchasing programs for maintenance shops and large carriers.

How can Lite-Check help reduce maintenance costs?

Lite-Check’s diagnostic tools help identify small issues before they lead to major breakdowns. By catching electrical shorts, air leaks, or ABS faults early, fleets can cut repair costs, improve uptime, and extend trailer life — all while keeping technicians safe and productive.
