Headlight Lens W246 for Mercedes-Benz B-CLASS

Replacement clear polycarbonate headlamp lens for the second-generation Mercedes-Benz B-Class (W246). Precisely moulded to OE geometry to restore optical clarity and sealing when the 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 flange for a clean bond to W246 housings (pre-facelift & facelift variants; match visually).

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

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

• Cost-Effective: Replace only the damaged lens while keeping your good internals.

Compatibility:

• B-Class (W246) — 2012–2018 (incl. 2015–2018 facelift; lens outline may vary by lamp technology/trim — match by VIN/visual).
  Not for W247 (2019–Present).

Related Part Number Families (cross-refs):
Typical complete-lamp families: A246-906-xx-xx (LH) / A246-907-xx-xx (RH). Lens subcomponents use variant-specific suffixes — verify by VIN and the stamp on your existing lens.

What’s Included / Not Included:

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

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

Installation Notes (Pro Tips):

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

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

• Use quality 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 — replacing the lens does not change RHD/LHD cut-off.

Q&A
Q1: Will a new lens stop condensation? Usually yes, if vents are clear and the lens is bonded with the correct sealant.
Q2: Is adhesive included? No. Use automotive-grade butyl or PU headlight sealant.
Q3: Can this lens convert pre-facelift to facelift styling? No. Profiles can differ; order the lens that matches your lamp by VIN/visual.
Q4: Left or Right — which do I choose? Order the side matching your damaged lamp. On RHD vehicles, Left = driver, Right = passenger. Verify by VIN and lens outline.
