CMU released papers and videos showing their new smart headlight system which improves visibility by constantly redirecting light to shine between particles of rain. This involves a camera to track the motion of rain and snow and then applying algorithms to predict where those particles will be and then shooting the light so as not to be there and repeating this process so that it appears seamless to the driver!
Now the CMU team is working on a more compact version to be installed in a car for road-testing.
