Factory-tested before dispatch, it bolts onto existing projector assemblies without requiring wiring modifications or computer coding, making it a straightforward upgrade for European road conditions.
Benefits & Practical Tips
- Plug-and-play integration removes the guesswork of rewiring harnesses or recalibrating headlight leveling sensors.
- Apply non-conductive dielectric grease to the terminal pins before mounting to shield against road salt and persistent humidity corrosion.
- If one side fails repeatedly, replace both ballasts simultaneously to maintain matched color temperature and consistent beam symmetry across the front fascia.
