Five Key Benefits

Comprehensive OE Blueprint Alignment & Dual-Platform EV/PHEV Compatibility
Meticulously cast to mirror genuine structural specifications, this front headlamp housing ensures an uncompromised, flush integration on the BYD Han (2020–2026). To optimize global sourcing logistics, the listing targets exact drivetrain sub-models: providing a 1:1 original replacement for EV (Pure Electric) frameworks under OEM numbers HCE-4121010D (Left Hand / Driver Side) and HCE-4121020D (Right Hand / Passenger Side), whilst guaranteeing cross-compatibility for DM-i / DM-p (Hybrid) variants via factory designations HC-4121010F (Left) and HC-4121020F (Right). Designed for low-voltage systems, the module natively accommodates the vehicle's proprietary Dragon Beam matrix controller, neutralizing CAN-bus diagnostic faults and dashboard warnings without secondary software coding.

Dragon Beam Matrix Architecture & Dynamic Sequential Illumination
An elite engineering upgrade, this assembly integrates the vehicle's iconic Dragon Beam matrix LED technology, driven by a massive grid of 300 premium, solid-state LED emitters. Incorporating pre-programmed dynamic flowing turn signal animations, the solid-state design delivers near-zero latency response times and a verified lifecycle surpassing 50,000 operational hours. Coupled with precision-molded aspherical optical lenses, the system creates an adaptive, high-density light distribution pattern that entirely eliminates diode flickering, beam degradation, and blind spots.

Energy-Stabilized 42W Draw & High-Lumen Compliant Beam Cutting
Operating under a calibrated 42W structural load allocation (15W Low Beam / 15W High Beam / 12W DRL), this assembly preserves critical high-voltage battery range for luxury NEVs while delivering elite photometric output (greater than or equal to 3200lm low beam / greater than or equal to 6400lm high beam). The crisp 6000K daylight-white temperature significantly mitigates driver visual fatigue during cross-border heavy hauling. The internal optical mask yields an ultra-sharp, anti-glare horizontal cut-off line that is strictly ECE R112 and DOT road safety compliant.

IP67 Ingress Armor & Thermal Management for Extreme Climates
Carrying a laboratory-certified IP67 ingress certification, the unit is hermetically sealed against high-pressure car wash jets, heavy monsoons, and fine sand penetration. Moving beyond standard market replacements, it features dual-layer pressure-equalizing breathing channels that dynamically evacuate internal thermal moisture, preventing lens condensation caused by rapid ambient temperature drops. The internal cooling substrate is engineered to stabilize performance across a rigorous automotive thermal range of -40°C to +85°C.

High-Impact ABS/PC Housing with OEM Dragon-Scale Texturing
The main structural bucket is injection-molded from premium, impact-resistant ABS polymer to deaden prolonged road vibrations, paired with a specialized heavy-duty Polycarbonate (PC) outer lens. The lens surface is armored with an advanced, UV-stabilized hard coat that safeguards against surface abrasions, environmental yellowing, and hazing. The exterior casing features an exact replication of the original "dragon-scale" textured trim, ensuring flawless cosmetic and aesthetic synchronization for global wholesale distribution and bulk supply chains.
