Specialist Inspection & Installation Points
-
HID Components: These units typically use D3S bulbs and high-voltage ballasts. Verify if these electronics are included or if the buyer needs to swap their existing modules.
-
Mounting Brackets: Check the three primary plastic mounting tabs for any hairline cracks; intact tabs are essential for maintaining proper beam alignment.
-
Lens Condition: At this age (2012–2016), check carefully for “crazing” (heat-related micro-cracks in the plastic) or pitting from road debris.
-
Seal Integrity: Ensure the thick rubber perimeter gasket is supple and not dry-rotted to prevent moisture ingress.
