The 4409X-R is a 35W, 12.8V PAR36 incandescent sealed beam lamp designed as a combination rear light for agricultural and utility tractors. Featuring a transparent red background lens, this sealed beam works in conjunction with a separate small bulb to deliver combined tail and work lighting from a single sealed unit. The rugged PAR36 construction houses the filament, reflector, and lens in one sealed glass assembly, protecting internal components from dust, moisture, and vibration common in field environments. Rated at 35W and 12.8V, this lamp is engineered for 12-volt electrical systems found across a wide range of classic and modern tractor platforms. The double-contact screw terminal base provides a secure, stable connection in demanding applications. Sold individually, the SB-4409X-R is a direct replacement for OEM part numbers used by International Harvester, Farmall, John Deere, Allis Chalmers, Case, Massey Ferguson, Minneapolis Moline, Oliver, White, and other major agricultural equipment manufacturers.
