Genuine Bentley Bentayga LED Headlight Assembly (Left)

Part Number: 36A941005F

The 36A941005F is the primary Left-Hand Side (LHS) LED headlight unit for the First Generation (2016–2020) Bentley Bentayga. This is a “Full LED” assembly, distinguished by Bentley’s “cut crystal” internal glassware design. It provides exceptional night-time clarity and serves as a major aesthetic centerpiece of the vehicle’s front fascia.

Technical Specifications

• Position: Front Left (Nearside / Driver side in RHD, Passenger side in LHD).

• Compatibility: * Bentley Bentayga (Pre-Facelift): 2016, 2017, 2018, 2019, 2020.

  • Fits W12, V8, Diesel, and Hybrid models.

• Technology: High-Intensity Full LED (Matrix-style lighting).

• Configuration: Designed for Left Hand Drive (LHD) markets (Non-USA/North American Specification).

Key Features

• Intelligent Lighting: Supports advanced beam-forming technology that can adjust the light pattern to avoid dazzling oncoming traffic while maintaining maximum peripheral illumination.

• Daytime Running Lights (DRL): Features the iconic LED halo ring that functions as both a signature light and a high-visibility turn signal.

• Internal Housing: Typically features a high-luster Chrome internal finish. (Note: Blackline or Speed models may use a different suffix for “Dark Tint” optics).

Common Failure Symptoms

• Internal Condensation: While minor fogging can be normal in temperature shifts, standing water or persistent heavy droplets indicate a failed seal or a hairline crack in the polycarbonate lens.

• LED DRL Yellowing: If the outer “halo” ring appears yellow or dimmer than the other side, the internal LED light guide is likely degrading.

• Adaptive Faults: A “Headlight Range Control” or “Adaptive Lighting” error on the dash often indicates a failure of the internal leveling motors or the control modules attached to the housing.

Installation & Programming Notice

Critical: To replace this headlight, the front bumper must be removed. Furthermore, this unit is a “smart” module. After mechanical installation, it must be coded and calibrated (Basic Setting) using Bentley-specific diagnostic software (ODIS) to ensure the beam height and adaptive functions are synchronized with the vehicle’s suspension sensors.

Fitment & Suffix Verification

The “F” suffix is specific to certain regional markets and production periods.

• USA/Canada Models: Typically require a different part number (e.g., 36A941005H) due to integrated side markers and different beam pattern regulations.

• Facelift Models (2021+): Use the 36A941015 series, which are not physically compatible with pre-facelift vehicles.

To ensure 100% compatibility with your vehicle’s wiring harness and regional lighting laws, please provide your VIN.
