Phillips Industries has developed a new tool that can notify drivers of inoperable trailer lights to help prevent CSA violations.One of the top violations under CSA are inoperable trailer lights, Phillips said, and the Lite-Sentry can help prevent that. The device monitors the exterior trailer lighting for failures and notifies the driver by an indicator light mounted on the front of the trailer so a repair can be made.Lite-Sentry is integrated and completely sealed into a Phillips Sta-Dry electrical harness and is designed to work with all 12V LED exterior trailer lighting that draws more than 19 milliamps. The current patent-pending Lite-Sentry is for chassis only. Future products will be introduced for other trailer configurations.
