Key Features
- Converts 10-pin halogen wiring to 12-pin Bi-Xenon headlight pinout
- Built-in capacitor smooths PWM signals and eliminates flickering
- Plug-and-play design
- Preserves low beam, high beam, DRL, and marker functions
- OEM-style connectors and proper wire gauge for reliable performance
Important Notes / Limitations
- No auto-leveling support — this harness does not support leveling motors or adaptive headlight functionality
- Use this adapter only for OEM Bi-Xenon headlight units
Why Use This Harness
Many aftermarket or OEM Bi-Xenon headlights rely on a 12-pin interface. On older MK5 / PQ34 models, the factory harness was 10-pin halogen. This adapter fills the gap and lets your Bi-Xenon units operate correctly—flicker-free and stable—without wiring hacks or coding.
Fitment & Compatibility
- Platform: MK5 / PQ35 with 10-pin halogen wiring
- Intended for use with OEM 12-pin Bi-Xenon headlights
- Not for adaptive, matrix, or non-standard lighting systems
- If you’re unsure: send me connector photos or your VIN and I’ll verify the correct harness for your setup
