Truck-Lite’s lensed Sky-Lite is designed to allot external sunlight to assist with trailer interior lighting without the need for added power or wiring. The polycarbonate product is engineered to mount on the upper sidewall of a trailer or body, giving a small windowed appearance and allowing natural light to enter the trailer, increasing daytime visibility.

The Sky-Lite fits a 4-inch-diameter hole cut into the sidewall of a trailer or body and is built for simple installation with a snap-in design and a peel-and-stick adhesive gasket.
