Clever concept.

The headlight is replaced by a projector.

The image being projected is of, for example, an LCD screen.

The image on the LCD screen is created by a camera on the front of the car that images the rain drops in real time.

A processor 'removes' the rain drops from the image.

Thus the light from the projector is solid beam of light except where the raindrops are. The light that would have illuminated a rain drop is removed. Thus the rain drops are non-illuminated, making it easier to see while driving in the rain at night.

Very clever, but what else might this system make 'disappear' from view - there could be some dangers/downsides involved.....

Ya, suicide seekers on their way down from overhead bridges. :) Flying gravel or debris would have to be distinguished but the psychometric effects of a pulsing/flickering light source could be the biggest obstacle.
