2x BMW M4 F82 F83 F32 F33 headlights Full Adaptive LED LCI SET

Part Numbers: 63117478157 (Left) / 63117478158 (Right) (Commonly known as the “Icon Adaptive LED” units)

This LCI (Life Cycle Impulse) headlight set is the premium lighting option for the F32 4 Series and F82 M4. These “Icon” units represent a major design shift from the traditional circular “Corona Rings” of earlier models to a more aggressive, hexagonal 3D DRL signature. As Full Adaptive LED units, they utilize high-efficiency light-emitting diodes for every function, including low beams, high beams, cornering lights, and turn signals.

Technical Specifications

• Compatibility:

  • BMW 4 Series: F32 Coupe, F33 Convertible, F36 Gran Coupe (LCI 2018–2020).

  • BMW M4: F82 Coupe, F83 Convertible (LCI 2018–2020).

  • Retrofit: Can be installed on Pre-LCI (2014–2017) models with a specialized wiring harness and coding.

• Technology: Full LED Matrix with BMW Selective Beam (Anti-dazzle).

• DRL Style: Hexagonal “Iconic” 3D LED tubes.

• Turn Signal: High-mounted LED “eyebrow” integrated into the housing.

Key Performance Features

• BMW Selective Beam: This intelligent high-beam assistant uses the car’s KAFAS camera to detect oncoming traffic and “mask” them out of the light pattern. This allows you to drive with high beams active without blinding other motorists.

• Variable Light Distribution: The light pattern adjusts automatically based on speed; it widens at low speeds to illuminate sidewalks and narrows/intensifies at high speeds for maximum reach.

• Predictive Cornering: The LED projectors swivel in anticipation of a turn, following the steering angle to light up the apex of a corner before the car enters it.

• 6000K Color Temperature: Provides a crisp, daylight-white output that enhances road sign contrast and significantly reduces eye strain during long-distance night driving.

Professional Installation & Cataloging Notes

When preparing these units for sale or installation, ensure all technical requirements are met:

1. Module Inventory: For a “Complete” set, each housing requires specific external control modules:

   • Main LED Control Units (one per side).

   • Cornering Light Modules.

   • LED Turn Signal/DRL Modules (attached to the exterior of the housing).

2. Coding Requirements: These units must be initialized and “VO Coded” to the vehicle’s FEM (Front Body Electronics Module). If retrofitting to a Pre-LCI car, the vehicle order must be modified to include option code 552 (Adaptive LED).

3. Hardware Alignment: After installation, a digital headlight beam setter is required to calibrate the vertical and horizontal aim to ensure compliance with road safety standards.
