BULB EXAMINATION FOR ON/OFF

The FTS Bulb Examination Proficiency Test is designed to challenge the forensic examiner who may examine automotive bulbs to determine On/Off status at the time of bulb damage. Bulb impact is produced under laboratory controlled conditions to improve precision in filament deformation. Tests consist of two commercially available automotive bulbs. Each distributed bulb is examined by a qualified examiner to ensure homogeneity of filament characteristics.
