About this part
Headlights on your GLS-Class X166 provide visibility and safety in darkness and poor weather. A cracked, foggy or failed headlight is a safety risk and a common reason for failing vehicle inspections.
Frequently asked questions
What should I look for when buying replacement headlights for the Mercedes-Benz GLS-Class?
Ensure the unit matches your GLS-Class X166 exactly. Check whether it's for the left or right side and whether it includes bulbs or ballasts, as these may be sold separately.
Are aftermarket headlights road-legal?
Quality aftermarket headlights with proper type approval (E-mark) are road-legal. Avoid units without certification, as incorrect beam patterns can blind oncoming traffic and fail inspections.
