Quick answer: This LED headlight is intended for the Mercedes-Benz GLA W156, with the product details specifying 2015-2019 vehicles and a halogen-to-LED upgrade path. Compatibility still depends on the VIN, production month, original lamp type, connectors, modules, facelift status and regional beam pattern. Confirm these details before ordering.

Pre-order verification
- VIN, production month, trim and sales market.
- Pre-facelift or facelift W156 front-end identification.
- Original headlight part numbers, labels, rear connectors, modules and bracket photographs.
- Factory halogen, xenon, Intelligent Light System, leveling and washer equipment.
- Left-hand-drive or right-hand-drive beam requirements and local regulations.
Coding and modules
A halogen-to-LED conversion can require wiring adapters, coding, resistors, control modules or diagnostic changes to prevent dashboard warnings. Confirm which low-beam, high-beam, DRL, indicator, leveling and adaptive functions are supported. “Plug-and-play” should be verified against the exact original lamp system.
Installation difficulty
This is a medium-to-advanced retrofit. Bumper removal, electrical checks, waterproof sealing, lamp alignment, beam aiming and Mercedes-compatible diagnostics may be needed. Test every lighting function before road use.
