Truck-Lite 97034 Rectangular Black Foam Mounting Gasket for Super 21 Series Clearance Marker Lights

Establish an airtight environmental seal and absorb destructive road shock with the premium cushioning of the Truck-Lite 97034 Rectangular Black Foam Mounting Gasket. Engineered specifically to fit Truck-Lite Super 21 Series rectangular sealed clearance and marker lamps, this OEM-grade foam gasket is an indispensable component for heavy-duty fleet maintenance facilities, commercial truck repair bays, and long-haul trailer operations.

When installing marker lamp assemblies directly onto aluminum, steel, or fiberglass vehicle bodies, tiny surface deviations can let water slide past the housing. The 97034 mounting pad compresses flawlessly to create a moisture- and dust-resistant barrier, keeping out corrosive road salt, highway grime, mud, and water ingress. By stopping moisture from building up behind the lamp assembly, it actively guards your electrical components from severe panel rust and the green-wire corrosion that sparks sudden circuit failures.

Constructed from a premium-grade, high-density black foam blend, this gasket features a total height of 2.4 inches, a total width of 6 inches, and a tight 0.23-inch thickness. This generous cushioning doubles as a vital vibration dampener, isolating your lighting units from the intense structural frame vibrations that fracture internal electronics over rough highway routes. Its exact rectangular layout supports standard and reflectorized lenses—including installations engineered to meet PC side-marker requirements on a 45-degree angle with auxiliary reflectors.
