Truck-Lite 40275C Sky-Lite Clear 4" Round Replacement Lens (For 0.25" Composite Panels, Dome & Utility Openings, Snap-Fit with Adhesive Gasket, Impact-Resistant Polycarbonate)

Bring instant, zero-power daylight illumination to your trailer cargo interior with the specialized Truck-Lite 40275C Sky-Lite Round Clear Lens. This innovative 4-inch round clear polycarbonate lens functions as an integrated cargo box skylight. By allowing ambient external sunlight to flood into the trailer body during daytime operations, it immediately improves loading zone visibility and driver safety without drawing from battery reserves or requiring complex electrical wiring configurations.

Engineered precisely for commercial dry vans, freight trailers, and delivery trucks, the Truck-Lite 40275C is specifically optimized to match popular 0.25-inch thick composite panels. The utility lens features a secure snap-fit mounting boundary combined with a premium, high-adhesion peel-and-stick foam gasket. When firmly installed, the gasket creates a tight, permanent, weather-tight barrier that seals out rain, dust, and heavy road spray. Molded from premium-grade, impact-resistant polycarbonate plastic, this clear skylight window is built to resist cracking, fracturing, or hazing from extreme climate changes or low-hanging branches.
