Chassis system
As an original equipment (OE) component for Dongfeng KC heavy-duty trucks (covering KC390, KC430, and KC480 tractor models), this left front combination lamp assembly (Part No. 3772010-C4400) is engineered with 100% alignment to the vehicle’s original design specifications. Its overall dimensions (290mm×172mm×125mm) and 3-point mounting hole layout (spaced 180mm apart horizontally) perfectly match the front-end frame of Dongfeng KC series vehicles, eliminating gaps or misalignment issues common with aftermarket alternatives. It directly connects to the vehicle’s original 24V electrical system via a 6-pin Delphi OE connector, ensuring seamless communication with the truck’s central control unit for stable function activation

PRODUCT DESCRIPTION
Integrated Multi-Function Lighting with OE-Grade Optical Performance
The assembly integrates five critical lighting functions, all calibrated to meet Dongfeng’s strict OE brightness and beam pattern standards:
Low Beam: Utilizes a high-precision parabolic reflector paired with a 55W halogen bulb (OSRAM OE-specified), producing a 14° cutoff beam that delivers 1,800cd of light intensity at 25 meters
High Beam: Features a multi-layered reflector design with a 60W halogen bulb, generating 19,500cd of peak intensity to illuminate up to 110 meters ahead, ideal for night driving on highways
Turn Signal: Equipped with 12 amber SMD LEDs (luminous flux: 150lm) with a flash frequency of 58±2 times per minute, ensuring high visibility even in heavy rain or fog
Position Light: Incorporates 8 warm-white LEDs (total flux: 90lm) with a 360° light distribution, maintaining clear vehicle contour visibility in dawn, dusk, or tunnel environments
Daytime Running Light (DRL): An added OE-exclusive function with 16 cool-white LEDs (flux: 220lm), automatically activating when the engine starts to enhance daytime driving safety
Durable OE-Grade Materials & Weather-Resistant Construction
Lamp Housing: Crafted from PC+ABS alloy plastic (supplied by BASF) with a 3mm thick wall, boasting impact resistance (passing 2m drop test on concrete) and thermal stability (operating temperature range: -45℃ to +90℃)—resisting warping from engine heat or freezing in cold climates.
Lens: Made of UV-stabilized PMMA material with a hard coating (hardness: HRC 3H), maintaining 92% light transmittance even after 4,000 hours of continuous sunlight exposure
Sealing System: Features a double-lip EPDM rubber gasket (compatible with automotive fluids) and ultrasonic welding at the housing-lens junction, achieving IPX8 waterproof rating—ensuring no water intrusion even in heavy rain or car washe
Rigorous OE-Quality Testing & Traceability
Every unit of this original assembly undergoes 12 strict quality inspections in line with Dongfeng’s OE testing protocols:
Waterproof Test: Immersion in 1.5m deep water for 60 minutes with no internal moisture.
Vibration Test: 3-axis vibration (10-800Hz, 50G acceleration) for 4 hours to simulate long-haul road conditions.
Thermal Shock Test: Cyclic temperature changes (-45℃ to +90℃) for 80 cycles to test material durability.
Light Performance Test: Calibration of beam pattern and intensity via automated optical testing equipment to ensure compliance with OE standards.
Each assembly is marked with a unique serial number (linked to production date and batch) for full traceability, supported by a 24-month OE warranty against manufacturing defects
User-Centric Installation & Maintenance Design
Mounting Design: Uses the original vehicle’s 3 M8×20 stainless steel bolts (included in the package) with pre-aligned mounting brackets—professional technicians can complete installation in 15-20 minutes, no drilling or welding required
Maintenance Access: A detachable rear cover (secured by 4 Phillips screws) provides easy access to bulbs and fuses; the 15A ceramic fuse (OE-specified) is located in a dedicated compartment, allowing quick replacement without disassembling the entire assembly
Documentation: Includes a 4-page OE installation manual (with exploded views of components and wiring diagrams) and a quality certificate—guiding users through proper installation and verifying compliance with Dongfeng’s OE standards
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
Warehouse Layout
-Five major regional accessory centers have been established globally (Southeast Asia, the Middle East, Africa, South America, and Europe) to achieve "next-day delivery" for mainstream accessories (covering customers within the regions).
Emergency Logistics Plan
-Emergency parts can be directly delivered within 48 hours via the "Dongfeng Exclusive Aviation Special Line" (such as engine ECU, brake valves and other key components).
Packaging Optimization
-Use shockproof and moisture-proof packaging (such as honeycomb cartons + pearl cotton), and reinforce fragile parts (such as glass, sensors), keeping the damage rate within 0.5%.
