Headlight W166 Xenon for Mercedes-Benz GL-Class

OEM-spec Bi-Xenon projector headlamp assembly for the first-gen Mercedes-Benz GL-Class (X166, pre-facelift 2013–2015). Built to factory geometry for correct beam pattern, mounting, and panel gap. Ideal replacement for crash damage, yellowed lenses, or failed internals. Sold per side.

Key Features

• OE Fit & Optics: Matches X166 GL pre-facelift lamp tooling for clean fit and factory beam cutoff.
• UV-Coated Lens: Clear polycarbonate with hardcoat to resist haze/yellowing.
• Module-Ready: Accepts your original ballast/igniter/AFS hardware.
• Road-Legal Pattern: RHD beam pattern for South Africa.

Compatibility

GL-Class (X166) — 2013–2015 pre-facelift Bi-Xenon/ILS vehicles. Not for GLS (X166 facelift, 2016–2019), ML/GLE (W166), or full-LED headlamps. Always confirm by VIN and visually match your original lamp (shape, brackets, connector).

Note: Bulb, ballast/igniter/ECU, AFS motor, rear caps, seals, and wiring not included — reuse your original electronics. Not a halogen-to-xenon conversion; like-for-like replacement only.
