Truck-Lite 40209R 40 Series Incandescent Red 4" Round Stop/Turn/Tail Light (24V, Shock-Mounted Bulb, PL-3 Connection, Sealed Lamp)
Bring standard-setting rear signaling reliability and heavy-duty 24V performance to your heavy machinery, military vehicle, export fleet, or commercial transport rig with the Truck-Lite 40209R 40 Series Stop/Turn/Tail Light. This 4-inch round, red incandescent lamp is a specialized fleet standard built to deliver dual-filament illumination for essential tail, braking, and turn signaling under demanding high-voltage setups.
Engineered to prevent downtime, the Truck-Lite 40209R features an internal shock-absorbent bulb mount. This unique design cushions the heavy-duty bulb filament from extreme road vibrations, bumps, and chassis shocks, significantly extending the service life of the light compared to standard bulb configurations. Sonically sealed inside a high-impact polycarbonate lens and housing assembly, this 24V lamp flush-mounts cleanly into standard 4.5-inch panel cutouts using rubber grommets and connects quickly using industry-standard PL-3 pigtail harnesses.
