The Phillips Industries Lite-Sentry is a trailer-chassis light monitoring system that alerts a driver when a light has gone out on a trailer.

A driver is notified of an exterior light failure by an indicator light mounted on the front of the trailer. The system is integrated and sealed into a Phillips Sta-Dry electrical harness and is designed to work with all 12-volt LED exterior trailer lighting that draws more than 19 milliamps.

The system was designed to cut down on CSA violations involving faulty trailer lights which Phillips says are one of the most common violations given during a roadside inspection.

Lite-Sentry is for trailer chassis only but Phillips says that more will be introduced for other trailer configurations.
