What about the color a car has been painted?  Before making expensive and
energy wasting attempts to solve the problem of low visibility, surely the
color of vehicles should be considered.  Paint all cars white or some bright
color and that would probably be more than sufficient to treat the problem.
From my experience, however it is not a matter of being able to see another
vehicle, but being able to recognized a vehicle, as in paying attention and
taking the time to mentally observe an area.  Lights are hardly a solution
the inability of people to react quickly enough to a situation.
