Headlight Lens W164 F/L for Mercedes-Benz ML-CLASS

Replacement clear polycarbonate headlamp lens for the facelift Mercedes-Benz ML-Class (W164, 2009–2011). Precisely moulded to OE geometry to restore optical clarity and sealing when your original lens is cracked, yellowed, or crazed. Sold per side — choose Left or Right.

What this is / isn’t:

• Included: 1× clear outer lens  (lens only).

Key Features:

• OE-Accurate Profile: Correct curvature and edge flange to bond cleanly to W164 F/L housings.

• Optical Clarity: UV-stabilised polycarbonate maintains sharp cutoff and factory DRL appearance.

• Seal-Ready: Smooth perimeter lip for reliable resealing using automotive butyl or PU headlight sealant.

• Cost-Effective: Keep your working internals; replace only the damaged lens.

Compatibility:

• ML-Class (W164) — 2009–2011 Facelift (F/L)

• Suitable for facelift lamps originally configured as Halogen or Bi-Xenon / ILS (AFS).
  Not for pre-facelift 2005–2008 W164, and not for GL-Class X164. Always confirm by VIN and visually match the lens outline.

Related Part Number Ranges (cross-refs):
Complete facelift headlamp families commonly fall under A164-906-xx-xx (LH) / A164-907-xx-xx (RH). Lenses are service subcomponents with variant-specific suffixes — verify via VIN and the stamp on your original lamp.

What’s Included / Not Included:

• Included: 1× clear headlamp lens only, side-specific.

• Not included: Housing, optics, control modules/ballasts, DRL/indicator boards, adjusters, gaskets, rear covers, or sealant.

Installation Notes (Pro Tips):

• Remove lamp; gently heat the perimeter (low-heat oven or careful heat gun) to soften factory adhesive.

• Separate lens; clean off all old butyl/PU and test-fit before bonding.

• Use high-quality butyl rope (reworkable) or automotive PU (permanent). Clamp/tape evenly while curing.

• Ensure vent ports are clear; replace desiccant if fitted.

• After refit, check headlight aim and perform a light-mist leak test to verify seal integrity.

• Beam pattern is set by the internal optics — the lens does not change RHD/LHD cutoff.

Q&A
Q1: Will a new lens stop condensation?
A1: Usually yes, provided the housing is clean, vents are open, and the lens is bonded with the correct sealant.

Q2: Is adhesive included?
A2: No. Use automotive-grade butyl or PU headlight sealant.

Q3: Can this lens convert pre-facelift to facelift?
A3: No. Pre-facelift and facelift W164 lenses differ. This lens fits 2009–2011 facelift only.

Q4: Left or Right — how do I choose?
A4: Order the side matching your damaged lamp. On right-hand-drive vehicles, Left = driver, Right = passenger. Verify against your VIN and lens shape.
