Dongfeng DFAC D9 Right front combination lamp assembly 3772020-T2102

This combination lamp assembly integrates three critical lighting functions in one compact unit: high/low beam headlights, front turn signals, and position/daytime running lights (DRLs). The high/low beam utilizes a precision-reflector optic system to deliver bright, far-reaching illumination for nighttime driving, while the amber turn signals feature fast-acting LEDs (or halogen bulbs, depending on configuration) for enhanced visibility to other road users. The integrated DRLs comply with modern vehicle safety standards, automatically activating to improve the truck’s conspicuity during daytime hours, reducing the risk of rear-end or side-impact collisions

Constructed to withstand the rigorous operating conditions of commercial trucks, the assembly’s lens is made from impact-resistant polycarbonate (PC) with an anti-UV coating—preventing yellowing, cracking, or scratching from prolonged sun exposure, road debris, or minor impacts. The housing is crafted from high-grade, corrosion-resistant ABS plastic that resists rust and degradation from road salt, moisture, and temperature extremes (ranging from -40°C to 90°C). Additionally, the internal electrical components are sealed with a IP6K9K-rated waterproof design, ensuring protection against heavy rain, pressure washing, and dust ingress, thus extending the lamp’s service life in demanding work environments

Designed for ease of installation, this combination lamp assembly supports a plug-and-play replacement process that requires no specialized tools or electrical expertise. It includes all necessary mounting hardware (screws, washers) that mirror the original parts, and the factory-matched electrical connector allows for instant connection to the truck’s wiring harness—no cutting, splicing, or rewiring needed. Most fleet technicians or DIY users can complete the installation in under 45 minutes by simply removing the old lamp, aligning the new assembly with the mounting points, securing the hardware, and plugging in the connector—minimizing truck downtime for maintenance

This right front combination lamp assembly (3772020-T2102) meets or exceeds international safety and quality benchmarks, including ECE R112 (for headlamp performance), ECE R6 (for turn signal lamps), and ISO 16949 (for automotive quality management). Each unit undergoes rigorous testing, including light pattern calibration, waterproof pressure testing, and vibration endurance testing (to simulate long-haul road conditions), ensuring reliable performance and compliance with vehicle inspection regulations in regions such as Europe, Asia, and North America. By choosing this certified assembly, users avoid the risks of substandard aftermarket lamps—such as uneven lighting, premature failure, or legal non-compliance
