AlphaRex Adaptive Headlight Decoder / Wiring Adapter

AlphaRex Adaptive Headlight Decoder / Wiring Adapter - Toyota GR86 / Subaru BRZ (2022+)

Eliminate Dashboard Errors & Ensure Seamless Headlight Integration

Upgrading the headlights on a Premium or Limited trim GR86/BRZ requires more than just a physical swap. The AlphaRex Adaptive Headlight Decoder is a critical component for owners of vehicles originally equipped with Steering-Responsive Headlights (SRH). Because AlphaRex NOVA and LUXX series headlights do not utilize the factory's heavy adaptive motors, the vehicle’s ECU will typically trigger a system error code. This plug-and-play adapter bypasses that error, allowing you to enjoy your new lighting without any persistent dashboard warnings.

What’s Included in the Box:

- Headlight Decoder/Wiring Adapter: A precision-engineered electronic bypass module.

- Direct-Fit Connectors: Designed to interface perfectly with the OEM harness and AlphaRex headlight assemblies.

- Mounting Hardware: Ties or clips to secure the module within the engine bay.

The AlphaRex Advantage

- Error-Free Operation: Specifically designed to suppress the adaptive headlight system error code that occurs when the steering-responsive motors are removed.

- Plug-and-Play Simplicity: No cutting, splicing, or complex electrical work required. The adapter uses factory-style connectors for a fast and reversible installation.

- High-Quality Circuitry: Built with automotive-grade components to withstand engine bay heat and vibrations, ensuring long-term reliability.

- Compact Design: The small footprint of the decoder allows it to be easily tucked away behind the headlight assembly for a clean, professional install.

- Regulatory Peace of Mind: By clearing dashboard error lights, this adapter helps keep your vehicle's instrument cluster clear and compliant for inspection.

Precision Tip: It is important to note that this adapter is a "canceller"—it removes the error code caused by the absence of the adaptive feature, but it does not enable the AlphaRex headlights to pivot with the steering wheel. If your car is a Base model without adaptive headlights, you do not need this adapter. For Premium/Limited owners, this is an essential "must-have" to finish your lighting build properly.
