Dongfeng VR Left headlight assembly 3772010-C1200 made in china

Exclusively designed as an Original Equipment (OE) replacement part for Dongfeng VR series commercial vehicles (including heavy-duty trucks and long-haul buses), this left headlight assembly (3772010-C1200) adheres to Dongfeng’s strict engineering standards for dimensional accuracy and mounting compatibility. It is fully compatible with Dongfeng VR models produced from 2020 onwards, matching the factory-installed headlight’s mounting points, wiring connectors, and contour with the vehicle’s front fascia—no modifications to the bumper, fender, or electrical system are required. Each unit undergoes pre-assembly alignment testing to ensure the light beam angle meets Dongfeng’s factory specifications, eliminating the need for post-installation adjustment and guaranteeing immediate optimal performance

Built to withstand the harsh operating conditions of commercial vehicles, the Dongfeng VR Left Headlight Assembly features a robust multi-layer construction. The outer lens is made of high-transmittance PC (polycarbonate) material with an anti-scratch and anti-fog coating, ensuring 90% light transmittance even after long-term use and resisting damage from small stones, road debris, or cleaning chemicals. The housing is constructed from impact-resistant ABS plastic with a weather-sealed design (IP67 waterproof rating), preventing water, dust, or moisture from entering the internal components—even during heavy rain, high-pressure car washes, or off-road driving. The assembly is also tested to endure extreme temperature fluctuations (-40°C to +85°C) and vibration levels (up to 15G acceleration), ensuring reliable operation over a service life of 50,000+ hours (equivalent to 5+ years of typical commercial use)

This headlight assembly meets global safety and regulatory standards, including ECE R112 (United Nations Economic Commission for Europe regulation on motor vehicle headlamps) and GB 4785 (China National Standard for Automotive Lighting and Light-Signaling Devices), ensuring legal compliance for road use in domestic and international markets. Beyond basic lighting, it integrates a dynamic turn signal function (optional, depending on vehicle configuration) that uses sequential LED activation to enhance the visibility of lane changes or turns, reducing the risk of rear-end collisions. The assembly also includes a built-in thermal management system: a small fan and heat sink dissipate heat generated by the LED chips, preventing overheating and maintaining consistent light output—even during prolonged high-beam use

The Dongfeng VR Left Headlight Assembly (3772010-C1200) is designed for user-friendly installation, featuring a bolt-on mounting system with pre-threaded holes that align perfectly with the vehicle’s front frame brackets. It comes with a factory-matched wiring harness connector (12-pin for standard models, 16-pin for units with dynamic turn signals) that plugs directly into the vehicle’s existing electrical system, eliminating the need for wire splicing or adapter kits. A trained technician can complete installation in approximately 45 minutes using only basic hand tools. For maintenance, the modular design allows for easy replacement of individual components (e.g., LED bulbs, turn signal modules) without removing the entire assembly, reducing repair costs and downtime. The PC lens also resists yellowing over time, minimizing the need for frequent cleaning or replacement
