Headlight Lens W177 for Mercedes-Benz A-CLASS

Replacement clear polycarbonate headlamp lens for the current-generation Mercedes-Benz A-Class — Hatchback (W177) and Sedan (V177). 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 bonding flange for a clean seal to W177/V177 housings.

• Optical Clarity: UV-stabilised polycarbonate maintains sharp cutoff 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 and retain your working internals.

Compatibility:

• A-Class Hatchback (W177) — 2019–Present

• A-Class Sedan (V177) — 2019–Present

• Works with LED High Performance and MULTIBEAM LED variants (outer lens outline shared; internals differ).
  Not for earlier W176 (2013–2018). Always confirm by VIN and visually match the lens outline.

Related Part Number Families (cross-refs):
Typical complete-lamp families: A177-906-xx-xx (LH) / A177-907-xx-xx (RH). Lens subcomponents have 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 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 LED optics — replacing the lens does not change RHD/LHD cutoff.

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 LED High Performance ↔ MULTIBEAM? No. Those differences are internal (modules/ECUs). This lens supports like-for-like repairs.
Q4: Left or Right — which do I choose? Order the side matching your damaged lamp. On right-hand-drive vehicles, Left = driver, Right = passenger. Verify against your VIN and lens outline.
