Headlight Lens W164 P/F for Mercedes-Bens ML-CLASS

Replacement clear polycarbonate headlamp lens for the Mercedes-Benz ML-Class (W164) pre-facelift. 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 for a clean bond to W164 pre-facelift housings.

• Optical Clarity: UV-stabilised polycarbonate maintains sharp beam cut-off and factory DRL appearance.

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

• Cost-Effective: Renew only the damaged lens and keep your working internals.

Compatibility:

• ML-Class (W164) — 2005–2008 Pre-Facelift
  Not for 2009–2011 facelift W164 (different lens outline) and not for GL-Class X164. Always confirm via VIN and visual match.

Related Part Number Ranges (cross-refs):
Complete pre-facelift W164 lamp families commonly fall under A164-906-xx-xx (LH) / A164-907-xx-xx (RH); lens subcomponents use variant-specific suffixes. Verify by VIN and the stamp on your original lens.

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 the factory adhesive.

• Separate lens; remove all old butyl/PU and test-fit before sealing.

• Use 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 do a light-mist leak test to confirm seal integrity.

• Beam pattern is set by the internal optics — replacing the lens does not change RHD/LHD cut-off.

Q&A
Q1: Will a new lens stop condensation?
A1: Usually yes, provided the housing is clean, vents are open, and the new 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 be used on the 2009–2011 facelift ML?
A3: No. Facelift W164 lenses are different. Use the W164 F/L lens for those years.

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