Founded in 1986, LITE-CHECK was the first company to offer electronic testers for commercial trailers. LITE-CHECK product development has been driven by the needs of our customers. The first product of its kind was manufactured for the California Highway Patrol to improve inspection productivity and diagnosis reliability. LITE-CHECK products have evolved into products that truck and trailer manufacturers and maintenance shops cannot do without.
