SA3E-4121010 SA3E-4121020 Front LED Headlight Assembly For BYD Seal 6 LED IP67 Waterproof

Product Overview

Five Key Benefits

Dimensional Integration and System Protocol Synchronization
The assembly is configured to align with the mounting geometry and terminal architecture specified for the 2024–2026 BYD Seal 06 (DM-i and EV variants). Utilizing OEM references EA3E-4121010 and EA3E-4121020, the unit facilitates a direct mechanical substitution, ensuring structural parity with original factory installation points. The integrated terminal interface maintains signal compatibility with the vehicle's onboard CAN-bus communication system, facilitating a plug-and-play installation path that preserves native diagnostic functionality and electrical system integrity without requiring hardware re-configuration.

Solid-State Illumination and Operational Longevity
The lighting engine utilizes a solid-state LED array, replacing legacy filament-based modules to achieve instantaneous luminous flux upon activation. The internal optical path is calibrated to ensure uniform light distribution, designed to meet consistent performance thresholds throughout the component's service life. By eliminating mechanical switching components and high-heat elements, this solid-state architecture minimizes common maintenance requirements associated with diode degradation or circuit fatigue during continuous operation.

Power Consumption Profile and Spectral Distribution
Operating parameters are calibrated to adhere to the power load requirements defined by the original equipment manufacturer, supporting the vehicle’s specific energy-management profile. The projected light is maintained at a 6000K color temperature, a spectral output selected to align with visibility requirements for nocturnal and low-light environments. The lens optics are structured to produce a defined light-distribution pattern that facilitates road surface definition while maintaining standardized parameters for light-spill and glare management.

Hermetic Environmental Shielding
The assembly meets IP67 ingress protection standards, verified against particulate and fluid penetration under defined testing conditions. The structural design incorporates an environmental seal that isolates the internal diode array from atmospheric humidity, road-derived contaminants, and high-pressure fluid exposure. An integrated ventilation matrix is included to provide pressure stabilization, assisting in the prevention of internal condensation cycles during significant ambient temperature transitions.

Polymer Substrate and Surface Resilience
The housing is constructed using an ABS composite substrate, selected for its mechanical properties regarding vibration dampening and impact resilience. The primary lens element is formed from high-transmission Polycarbonate (PC), treated with a UV-stabilized coating to mitigate material oxidation and the rate of surface yellowing. This material configuration is designed to uphold optical clarity and structural rigidity throughout the designated service life of the component, consistent with established automotive manufacturing durability standards.
