BMW G20 G21 Headlights LCI FULL LED Complete Set AS NEW

Part Numbers: 63115A1AFA5 (Left) / 63115A1AFA6 (Right) (Note: Part numbers may vary slightly based on specific Shadowline or Adaptive Matrix options)

The LCI (Life Cycle Impulse) headlights for the G20 3 Series represent the modern design language of BMW, featuring a “flipped” L-shaped (or inverted “C”) Daytime Running Light (DRL) signature. This set is a significant departure from the Pre-LCI (2019–2022) models, offering a slimmer, more integrated look with the kidney grille.

Technical Specifications

• Compatibility: * BMW 3 Series (G20 Sedan / G21 Touring) LCI 2023–Present.

  • Fits 330i, 330e, M340i, and 320i models.

• Technology: Full LED (Low beam, High beam, and DRL).

• Design Type: Available in standard Full LED or the darkened M Shadowline finish.

• Optical System: Reflector-based LED for standard units or Projection-based for Matrix/Adaptive variants.

Key Performance Features

• Inverted DRL Signature: The unique L-shaped light tubes serve as both the Daytime Running Lights and the turn signals, pulsing when the indicator is active.

• Cornering & Adaptive Capability: On equipped models, the light distribution automatically adjusts based on steering input and speed to provide optimal illumination through bends.

• Matrix High-Beam Assistant: On higher-spec units, the Matrix functionality allows the high beams to stay active while selectively “dimming” sections of the light to avoid blinding drivers in front.

• Streamlined Housing: The LCI units are noticeably flatter than the previous generation, improving the vehicle’s aerodynamic profile and modernizing the front-end aesthetics.

Professional Installation & Technical Notes

Maintaining the “As New” condition and ensuring full functionality requires precise technical handling:

1. Component Protection: These headlights are part of the vehicle’s protected electronic network. After installation, “Component Protection” must be removed using BMW ISTA online diagnostics to authorize the new hardware.

2. Coding and Software: The FLM (Front Light Electronics) modules must be initialized and parameterized. If the car was originally equipped with standard LEDs and you are installing Adaptive or Shadowline units, the Vehicle Order (VO) must be updated.

3. Module Inventory: A “Complete Set” should include:

   • Main LED Driver Modules (bolted to the housing).

   • DRL/Indicator Control Units.

   • Internal Ventilation Fans (crucial for managing the heat from high-output LEDs).

4. Hardware Check: Ensure all mounting tabs are intact; on “As New” units, there should be no evidence of stress whitening or plastic repair on the rear mounting brackets
