Abstract

While investigating traffic accidents that took place during darkness hours on unlighted area of carriage way, investigating authorities are interested in reasons that, from a technical point of view, could lead vehicle to run down a pedestrian or a stationary obstacle, to a collision of vehicles. Furthermore, while performing research on technical condition of a vehicle lighting system using modern equipment, forensic autotechnician experts are faced with problems related to the lack of skills in using such equipment. Moreover, while solving certain issues related to the technical state of lighting system, posed questions are not fully disclosed by forensic autotechnician experts, “narrow” conclusions are made, so far as during examining technical state of vehicle lighting system, most forensic autotechnician experts do not apply to State Standard DSTU 3649:2010 requirements. This article details the order of actions of specialists, forensic experts while performing research on technical state of the vehicle lighting system using the modern OMA 684D device. The minimum values of headlamp intensity for certain types of headlights bulbs in according to Rules ECE UNO (Economic Commission for Europe the United Nations Organization) requirements are described. Recommendations for use of DSTU 3649:2010 are given while performing research technical condition of vehicle lighting system. To obtain result values in candelas, as required by DSTU 3649:2010, the calculation of the translation of the values of headlamps light intensity from luxes to candelas is offered. Minimum and maximum values of the headlamps light intensity for certain types of light distribution according to DSTU 3649:2010 are also indicated. The decoding of headlight types with values of light intensity is given. For better perception of the correctness of the research results, images of the control points location depending on the type of light distribution are indicated.
