Dedicated 24-Volt Engineering: Formulated specifically to operate reliably within 24V commercial vehicle electrical systems without the need for voltage step-down converters.
-
Vibration-Welded / Sonically Sealed Body: Tough polycarbonate lens and housing are fused together into a single component, ensuring maximum resistance to heavy downpours and high-pressure chemical washes.
-
Vibration-Dampening Shock Mount: Features an internal elastomeric bulb cradle that isolates the light filament from heavy chassis shaking, reducing bulb failure and fleet maintenance downtime.
-
Standard 4-Inch Circular Design: Fits seamlessly into all standard 4-inch industry footprints using standard 40 Series black rubber mounting grommets, brackets, or flanges (sold separately).
-
Industry-Standard PL-2 Connection: Built with an integrated 2-pin PL-2 socket on the back of the housing for quick, plug-and-play installation with standard right-angle or straight pigtail wiring harnesses.
-
Direct Legacy Fitment: Seamlessly replaces older, worn-out 24V configurations, including legacy Signal-Stat 4041W and 4047W series lights without structural body modifications.

Truck-Lite 40212 – 40 Series 4" Round Clear Sealed Incandescent Back-Up Reverse Light Head (PL-2 Connection, 24V)
Restore premium rearward visibility and heavy-duty safety compliance to your high-voltage equipment with the Truck-Lite 40212 40 Series 24-Volt Back-Up Light. Specifically engineered for 24V electrical architectures, this 4-inch round clear sealed reverse light head is an industry-standard replacement for international commercial fleets, military transport, heavy-duty vocational equipment, and specialized agricultural machinery.
Built to withstand the severe vibration and demands of commercial line-haul hauling, the Truck-Lite 40212 features a high-impact polycarbonate lens and housing that are permanently vibration-welded (sonically sealed) together. This airtight, single-piece casing forms an absolute barrier against fine dust, mud, and intense road spray. Inside, the high-output 24V incandescent bulb is suspended in a specialized internal shock mount that dampens rough chassis rattles and pothole impacts, drastically reducing premature filament failure.
