For BYD Song Pro Auto Headlight Parts 2nd Gen LED Headlamp Plastic Housing

Five Key Benefits

Rigorous Factory Blueprint Alignment & Multi-Batch EV/PHEV Compatibility
Meticulously cast to replicate genuine structural layouts, this front headlamp housing guarantees an uncompromised, flush integration on the 2nd-Generation BYD Song Pro / Song Pro DM-i / Song Pro DM (2021–2026). To facilitate flawless cross-border procurement, the component design achieves a 1:1 original match for factory part numbers SA2FC-4121010 (Left Hand / Driver Side) and SA2FC-4121020 (Right Hand / Passenger Side), providing authenticated cross-compatibility across regional assembly runs carrying suffixes A, B, D, J1, and DK. Configured for standard low-voltage vehicle electronics, the integrated circuit module natively interfaces with the factory harness, neutralizing CAN-bus diagnostic faults, dashboard warnings, and daytime running light sync errors without secondary software coding.

Dragon Face Identity Integration & Premium Solid-State Lighting
An elite hardware upgrade engineered to match the vehicle's signature Dragon Face styling profile, this assembly utilizes an automotive-grade, solid-state full LED architecture. The advanced diode network delivers instantaneous, zero-latency illumination and a verified operating lifecycle surpassing 50,000 service hours, effectively minimizing vehicle down-time and fleet maintenance intervals. Combined with high-reflective optical alignment sub-components, the system projects an adaptive, high-density beam that entirely eliminates flickering, dark spots, and premature diode degradation.

Optimized 36W Eco-Draw & Precision High-Lumen Safety Beam
Operating under a calibrated 36W structural load allocation (12W Low Beam / 12W High Beam / 12W DRL), this configuration provides excellent photometric output while conserving critical battery range for plug-in hybrid platforms (yielding greater than or equal to 2800lm low beam and greater than or equal to 5600lm high beam). The crisp 6000K daylight-white temperature replicates natural afternoon light to reduce driver visual fatigue during extended nocturnal hauling. The interior optical mask projects an ultra-sharp horizontal cut-off line that is strictly compliant with ECE R112 and DOT international safety standards to eliminate blinding glare for oncoming motorists.

Laboratory-Certified IP67 Ingress Defense & Aerodynamic Moisture Control
Carrying an official laboratory-certified IP67 ingress rating, the housing is hermetically sealed against high-pressure wash bays, torrential monsoons, and fine sand penetration. Moving beyond standard market replacements, the premium sealing configuration integrates specialized hydrophobic ventilation channels. These breathing tracks dynamically equalize interior air pressure and evacuate thermal moisture, completely neutralizing lens condensation and internal fogging caused by sudden ambient temperature drops while stabilizing thermal management across a rigorous automotive-grade range of -40°C to +85°C.

Vibration-Absorbing ABS/PC Substrate with Factory-Spec Exterior Trim
The main structural bucket is injection-molded from heavy-duty, impact-resistant ABS polymer to deaden prolonged road vibrations, paired with a premium Polycarbonate (PC) outer optical lens. The lens face is shielded by an advanced, UV-stabilized hard coat that safeguards against surface abrasions, environmental yellowing, and thermal hazing. The outer trim incorporates an exact replication of the original dragon-scale textured casing finish, ensuring flawless cosmetic synchronization and maximum asset protection for global bulk distribution networks and B2B wholesale supply chains.
