Truck-Lite 88-02210 – Signal-Stat Round Black Rubber Sealing O-Ring (Fits Signal-Stat 3762, 3763, 3860, 3861, 3862, 3863)

Protect your lighting assemblies against moisture, dust, and road debris with the genuine Truck-Lite 88-02210 Signal-Stat Round Sealing O-Ring. Specially engineered as a direct-fit replacement gasket, this black rubber O-ring creates an airtight, weatherproof barrier to preserve internal lamp wiring and extend overall light fixture life.

Formulated from high-grade, flexible rubber, the Truck-Lite 88-02210 maintains its elasticity and sealing power even under extreme temperature fluctuations, heavy road vibration, and constant weather exposure. Designed specifically for Signal-Stat series lamps (including models 3762, 3763, 3860, 3861, 3862, and 3863), this seal prevents corrosion-causing water ingress and ensures long-term operational safety.
