Headlight Lens X156 P/F for Mercedes-Benz GLA-CLASS

Replacement clear polycarbonate headlamp lens for the pre-facelift Mercedes-Benz GLA (X156, 2014–2016). Precision-moulded to OE geometry to restore optical clarity and sealing when your original lens is cracked, hazed, or yellowed. 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 X156 pre-facelift housings.

• 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: Renew only the damaged lens while retaining your good internals and electronics.

Compatibility:

• GLA-Class (X156) — 2014–2016 Pre-Facelift

• Fits lamps configured as Halogen or Bi-Xenon/ILS where the outer lens outline is shared (internals differ).
  Not for 2017–2020 facelift (MOPF). Always confirm via VIN and visually match the lens outline to your lamp.

Related Part Number Families (cross-refs):
Typical complete-lamp series: A156-906-xx-xx (LH) / A156-907-xx-xx (RH). Lens subcomponents carry variant-specific suffixes — verify via 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/modules, control units, DRL/indicator boards, adjusters, gaskets, rear covers, or sealant.

Installation Notes (Pro Tips):

• Remove 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 perform 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, provided 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 halogen ↔ xenon/LED? No. Those differences are internal (optics/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 by VIN and lens outline.
