Xenon HID Headlight Ballast for BMW Audi VW GMC Volvo 89034934 4L0907391
Restore original illumination intensity with this Xenon HID headlight ballast engineered as a direct drop-in replacement for worn-out OEM converter modules. Built with a D1S semi socket interface and factory-tested circuitry, it stabilizes high-voltage ignition to correct delayed arc startup, intermittent flicker, and progressive dimming without requiring full headlamp disassembly.
Benefits & Practical Tips
- Cross-check your current unit against the listed OEM numbers before uninstalling to guarantee accurate physical and electrical fitment.
- Mount the new ballast securely away from moisture sources and secure loose harness clips to prevent vibration-induced signal loss under rough terrain.
- Run a quick bench test before final bolting down to verify stable beam cutoff and consistent color temperature across both left and right headlights.
