    Vehicle Inspection and Analysis. Vehicles are inspected to determine how and why the accident happened. A few of the most common reasons our clients request a vehicle inspection and analysis are to determine: headlight, or brake light was on / off. This document proposes amendments to Federal Motor Vehicle Safety Standard (``FMVSS'') No. ; Lamps, reflective devices, and associated equipment, to permit the certification of adaptive driving beam headlighting systems, if the manufacturer chooses to equip vehicles with these systems.
