Protect your vehicle’s critical exterior lighting from moisture, dust, and vibration with the Truck-Lite 9520 Signal-Stat Round Sealing Gasket.

It is a highly popular replacement component for heavy-duty school buses, transit vehicles, and emergency service fleets.
Constructed from premium-grade, closed-cell white foam, this 7-inch round gasket provides exceptional compressibility and environmental resilience.

By forming an impenetrable barrier against road salt, rain, and pressure washing, it prevents premature bulb blowout, terminal corrosion, and housing condensation.
