Project Experience: Motorcycle Headlight Failure

A motorcycle was involved in an automobile accident that occurred after dark.  EMSL was asked to determine if the headlight of the motorcycle was on or off at the time of the accident.  EMSL examined the filament of the smashed headlight and found, with Scanning Electron Microscopy (SEM) and X-Ray Microanalysis (EDX), the presence of microscopic glass fragments bound to the filament, thus proving that the filament was hot at the time of the accident.
