Truck-Lite 97093 Round Black Foam Mounting Gasket for 5-Inch Front/Rear Auxiliary & Turn Signal Lights

Guard your commercial vehicle's high-visibility auxiliary lighting from water ingress and heavy chassis vibration with the Truck-Lite 97093 Round Black Foam Mounting Gasket. Specifically engineered as the exact OEM replacement surface seal for Truck-Lite's prominent 5-inch round front and rear auxiliary lighting families, this premium foam gasket is a vital, low-cost component for heavy-duty truck fleets, vocational repair shops, and long-haul trailer maintenance facilities.

When installing surface-mount turn signals or round auxiliary lamps directly onto metal, stainless steel, or fiberglass vehicle body panels, microscopic imperfections can allow moisture to pool behind the assembly. The 97093 mounting pad compresses perfectly under screw tension to form an airtight and watertight environmental barrier. This active shield permanently blocks out road salt, corrosive chemical de-icers, highway mud, and high-pressure power-washer spray—protecting your underlying wire configurations against the green-wire corrosion that triggers sudden electrical circuit shorts.

Constructed from a premium-grade, high-density black foam compound, this gasket features an exact circular profile measuring 5.38 inches in total height and width with a slim, flush-mounting 0.06-inch (1.52mm) thickness. This resilient padding doubles as a highly effective vibration dampener, isolating the delicate internal electronics of your front or rear turn signal lamps from the punishing chassis shock of severe-duty routes. It allows for flawless, secure surface attachment across flat panels and protective light housings alike.
