And that would be...?
********
As Scott Dorsey mentioned, the brake light bulbs can give an indication of
whether or not the lights were illuminated at the time of impact.
I can't confirm whether or not Scott's explanation if correct or not, but it
sounds plausible.
We used to have to check out vehicles where the operator claimed that a
defect in the vehicle caused an accident, and I noticed that police
technicians often removed the brake light bulbs or tail light assemblies,
and when I asked the technician why he was removing the bulbs, he said that
the brake light bulbs tell a story.
