-
❌ Xenon bulb, ballast/igniter/ECU, DRL board, rear caps, seals, wiring, levelling/AFS components
Installation Notes (Pro Tips):
-
Disconnect the battery before work; observe ESD precautions.
-
Transfer all original electronics (ballast/igniter/DRL board/levelling motor) and rear covers.
-
If your old lamp had condensation, dry the housing and renew seals/vent caps before refitting.
-
After install, adjust beam aim; if AFS/auto-levelling is fitted or modules were replaced, perform calibration/coding with Mercedes-capable diagnostics (Xentry/STAR).
Q&A
Q1: Can this convert halogen to xenon? No — halogen↔xenon require different wiring, sensors and control units. This is like-for-like replacement.
Q2: Bulbs and ballast included? No — reuse your originals or purchase separately (match your bulb and ECU type).
Q3: Will it fit AMG Line models? Yes, if originally equipped with Bi-Xenon. Confirm by VIN and connector/bracket layout.
Q4: Left or Right? Lamps are side-specific. On right-hand-drive vehicles, Left = driver, Right = passenger verify before ordering.
