Bentley GT GTC Headlight Left 3W1941015AB

Genuine Bentley Continental GT / GTC Headlight Assembly (Left)

Part Number: 3W1941015AB

The 3W1941015AB is a high-specification Bi-Xenon headlight unit designed for the Second Generation (2011–2018) Bentley Continental GT and GTC. These headlights are famous for their “jeweled” internal optics, which mimic the look of cut crystal, providing a signature luxury appearance even when the lights are off.

Technical Specifications

• Position: Front Left Hand Side (LHS / Driver Side for RHD, Passenger Side for LHD).

• Technology: Bi-Xenon (HID) High/Low Beam with integrated LED Daytime Running Lights (DRL).

• Compatibility: * Bentley Continental GT: 2011–2018.

  • Bentley Continental GTC: 2011–2018.

• Features: Includes Auto-Leveling and AFS (Adaptive Front-lighting System) for cornering.

Core Features

• Adaptive Front-lighting System (AFS): The projector lens swivels in the direction of the steering wheel, illuminating corners as you turn.

• LED Signature: The outer ring of the main lamp serves as the DRL, providing that unmistakable Bentley “four-eye” glow.

• Internal Finishing: Features a polished chrome interior bezel. (Note: If your vehicle has the Dark Tint specification found on ‘Speed’ models, you may require a different suffix).

Common Failure Points

• Ballast Failure: If the Xenon bulb flickers or fails to ignite, the control module (ballast) mounted to the bottom of the housing may have failed due to moisture or age.

• DRL Yellowing: Over time, the LED light pipes can degrade, causing the daytime running lights to appear yellow or dim.

• Condensation: Hairline cracks in the seal or a blocked vent can lead to internal fogging, which can eventually short out the internal AFS motors.

Installation & Programming

Critical: Replacing this unit typically requires removing the front bumper. Additionally, because the headlight contains an AFS control module, it often requires basic setting calibration via a diagnostic tool (like ODIS or VCDS) to ensure the beam is leveled and the cornering function is synchronized with the steering rack.

Important Suffix Check

The suffix “AB” denotes a specific hardware revision. Bentley used several iterations for this headlight (e.g., AC, AD, AE) to address electronics updates or regional requirements (LHD vs RHD).
