Truck-Lite 97706 Rectangular Black Foam Sealing Gasket (Replacement Housing Pad for 40 & 53 Series 4027 Stop Turn Tail Marker Lights)

Protect your vehicle's safety lighting from short circuits and stop moisture tracking with the heavy-duty seal of the Truck-Lite 97706 Rectangular Black Foam Sealing Gasket. Specifically engineered as a high-performance, close-cell cushioning profile for the classic Truck-Lite 40 and 53 Series multi-function lamps, this premium replacement gasket provides an air-tight, water-resistant interface between the lamp lens housing and your vehicle body panels. It serves as an essential fleet maintenance component to optimize the lifespan of your combination stop, turn, tail, and backup lighting systems, helping you remain fully compliant with Department of Transportation (DOT) and FMVSS 108 highway safety regulations.

Don't let environmental exposure cause premature, costly lamp failure. This gasket is stamped from high-density, ozone-resistant black foam designed to compress cleanly beneath mounting fasteners. Its specialized cellular mapping absorbs intense chassis vibrations, isolates the lens assembly from mechanical shocks, and effortlessly fills minor surface irregularities along metal vehicle bodies—making it a favorite option for Ford utility trucks, Freightliner vocational rigs, regional box trailers, and dry van bodies.

Physical deterioration can cause water entry, bulb corrosion, and ground wire failure. The 97706 serves as a defensive buffer against high-pressure road spray, road salts, coastal humidity, and corrosive chemical winter de-icers. When replacing or servicing your multi-purpose rear vehicle lighting, adding a fresh foam lens seal ensures your electrical connections remain completely weather-sealed.

Designed for a quick, accurate drop-in field installation, this gasket serves as a direct upgrade to replace older 99164R seals. It mirrors the exact perimeter configuration of the light housing, ensuring a stress-free replacement process for all standard 4010 and 4020 series footprint lamp modules.
