Installation Notes (Pro Tips):
Remove lamp; gently heat perimeter (low-heat oven or careful heat gun) to soften factory adhesive.
Separate lens and remove all old butyl/PU; test-fit before bonding.
Use butyl rope (serviceable) or automotive PU (permanent). Clamp/tape evenly while curing.
Ensure vent ports are clear; replace desiccant if fitted.
After refit, check headlight aim and do a light-mist leak test to verify seal integrity.
Beam pattern is set by the internal optics — the lens does not Change RHD/LHD cut-off.
Q&A
Q1: Will a new lens stop condensation? Condensation has several possible causes. Inspect the housing, vents and existing seal, and confirm that the lens is the faulty part before ordering.
Q2: Is adhesive included? No. Use butyl or PU sealant.
Q3: Can this lens convert halogen ↔ LED/Xenon? No. Those differences are internal (optics/modules/ECUs).
Q4: Left or Right — which do I choose? Order the side that matches your damaged lamp. On RHD vehicles, Left = passenger, Right = driver. Verify via VIN And lens outline.
Condition: New aftermarket replacement part. Not an original Mercedes-Benz part; brand and model names are used only to show fitment.
