The filaments of headlights are examined after a head-on accident.Both filaments are observed to have extensive deformation.Which of the following scenario likely applies to the accident?

Question

Quizplus · Accepted Answer

Both filaments being extensively deformed suggests that both the headlights were on at the time of the crash, as the filaments are heated and under stress when the headlights are active. If the headlights were off, the filaments would not have been deformed. Option B can be ruled out for the same reason. Option C is incorrect, as the deformation of the filaments indicates that the headlights were on, so it is possible to tell if the headlights were on or off at the time of the crash. Option D is not necessary in this scenario, as the deformation of the filaments is enough evidence to suggest that the headlights were on.
