High-quality replacement headlight housing designed for Mercedes-Benz GLS-Class SUV models based on the X166 platform (2016–2019), equipped with Bi-Xenon or ILS xenon headlights. Intended to replace a damaged or cracked original xenon headlight body while retaining your existing lens, xenon projector, bulbs, and electronic control units.
