Headlight Lens W176 F/L for Mercedes-Benz A-CLASS

Replacement clear polycarbonate headlamp lens for the facelift Mercedes-Benz A-Class (W176, 2016–2018). Designed to restore optical clarity, sealing, and OEM appearance 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: Precisely moulded to match facelift W176 headlamp housings for perfect fit.

• Optical Clarity: UV-hardened polycarbonate maintains high light transmission and sharp beam cutoff.

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

• Cost-Effective Repair: Replace only the outer lens instead of the complete headlamp assembly.

Compatibility:

• A-Class (W176) — 2016–2018 Facelift

• Fits LED, Bi-Xenon/ILS, and Halogen headlamps where outer lens shape is shared (internals differ).
  Not suitable for pre-facelift A-Class (2012–2015). Always confirm via VIN or visual match with your current headlamp.

Related Part Number Families (cross-refs):
Typical complete-lamp families: A176-906-xx-xx (LH) / A176-907-xx-xx (RH). Lens subcomponents vary by variant — verify via VIN and existing lens stamping before purchase.

What’s Included / Not Included:

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

• Not included: Housing, optics, LED modules, DRL boards, gaskets, wiring, or sealant.

Installation Notes (Pro Tips):

• Remove lamp and gently heat perimeter (low-heat oven or careful heat gun) to soften original adhesive.

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

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

• Ensure vent ports are clean; replace desiccant if present.

• Check headlight aim and perform a light-mist test to confirm sealing.

• The beam pattern is determined by internal optics, not the lens — this part does not affect LHD/RHD cutoff.

Q&A
Q1: Will this lens stop condensation?
A1: Usually yes, if vents are clear and the lens is sealed properly with fresh adhesive.

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

Q3: Can I fit this to the pre-facelift 2012–2015 A-Class?
A3: No. The pre-facelift lens profile differs. Use the W176 P/F lens instead.

Q4: Left or Right — which side should I order?
A4: On right-hand-drive vehicles, Left = driver, Right = passenger. Confirm visually and by VIN before ordering.
