Trailer Light Scanner

Whether tractor trailers are your bread and butter, or just part of your workday, light testing is a fact of life. A Trailer Light Scanner makes the job of trailer light testing a lot faster and easier since it powers your trailer’s lighting circuits in sequence. You check the operation of all lighting functions in a single walk-around instead of two or three. In about 60 seconds, the whole lighting system is checked for operation, shorts, and proper grounding. Turn walk time into work time with a Trailer Light Scanner.
