Right Front Combination Headlamp Assembly OE 3772020-C4400 for Dongfeng KC Heavy Trucks

This genuine right front combination headlamp assembly (OE:3772020-C4400) is original factory dual-beam lighting component exclusively engineered for Dongfeng KC heavy-duty trucks, integrating independent high beam and low beam reflective cavities in one housing to satisfy all nighttime road illumination demands. It adopts high-transmittance anti-yellowing PC transparent lens and vacuum electroplated reflective bowls to concentrate light output without dazzling oncoming traffic. The reinforced plastic rear housing comes with pre-installed bulb sockets, dustproof sealing caps and four fixed mounting brackets for direct bolt-on replacement. This headlamp passes DFCV OEM IP65 waterproof, million-cycle vibration fatigue and high-low temperature alternating aging lab tests. Independent third-party automotive lighting inspection verifies its full dimensional and wiring interface consistency with factory original lamps, acting as a standard direct replacement for collision-damaged headlights for long-haul logistics fleets and heavy truck repair workshops worldwide.

PRODUCT DESCRIPTION

Dual Independent Beam Cavities & Anti-UV Anti-Yellow PC Lens

This OE 3772020-C4400 right combination headlamp is strictly molded per Dongfeng KC original factory drawings, equipped with two separated high/low beam reflective cavities to deliver focused, layered illumination for highway and urban night driving. The outer PC lens is coated with premium anti-UV protective film to resist fogging, yellowing and light attenuation under long-term outdoor sun exposure. Internal vacuum electroplated reflectors maximize light utilization efficiency, while four symmetrical pre-mounting lugs perfectly match the front bumper mounting holes of Dongfeng KC trucks. Standard pre-wired plug sockets realize plug-and-play assembly without cutting or refitting vehicle wiring.

Dim Split Beam Lighting, Yellowed Foggy Lens & Ill-Fitting Aftermarket Headlights

Heavy truck fleet managers and repair technicians often encounter cheap aftermarket headlights with single weak beam, uncoated lenses that quickly turn yellow and blur night vision, and mismatched mounting brackets causing assembly gaps, water seepage and frequent bulb burnout. This genuine OEM dual-beam combination headlamp solves all these safety and maintenance pain points: separated high/low beams provide clear long & short distance vision, anti-UV lens maintains stable light transmittance for years, 1:1 OEM mold eliminates fit deviation and IP65 waterproof structure prevents internal fogging in rainy and muddy transport environments.

DFCV Mold Engraved OEM Code & Multi-Round Harsh Environment Lab Certification

As a core front safety lighting spare part, this combination headlamp fully complies with Dongfeng Commercial Vehicle official production quality control standards, with permanent engraved DFCV brand and OE part number on the lamp housing to confirm authentic OEM raw material and production standard. Every finished headlamp completes three mandatory professional lab tests: IP65 waterproof tightness test, million-time road vibration fatigue test, and extreme high-low temperature alternating aging test, maintaining stable lighting performance under cold, dusty, humid and high-speed heavy haul scenarios. Original injection mold production eliminates dimensional deviation and assembly gap issues on Dongfeng KC vehicles.
