What’s Included / Not Included:

Installation Notes (Pro Tips):

• Disconnect the battery before removal.

• Transfer your original LED drivers/ECUs and rear covers to the new housing.

Q&A
Q1: Can this convert halogen/bi-xenon to LED? No — conversions require different wiring and ECUs. This is a like-for-like LED facelift replacement.
Q2: Does it include LED drivers or DRL modules? No — reuse your originals or purchase by exact OE number.
Q3: Is it side-specific? Yes. On right-hand-drive vehicles, Left = driver, Right = passenger. Verify before ordering.
Q4: Will it fit AMG Line? Yes — as long as the car has factory LED facelift headlamps; confirm by VIN and connector/bracket layout.
