Body Accessories Sourcing: Lighting, Mirrors & Bumpers
AI Summary: Sourcing body parts such as lighting, mirrors, bumpers and door accessories should verify vehicle model, model year, trim and part number. For headlights, check light source, lens, waterproofing and adjustment; for mirrors, check power adjustment, heating and blind spot functions. For exterior parts, installation gaps, clips and paint finish affect safety and appearance; for accident parts, inspect internal brackets.
