Sometimes when I'm making a U-turn, a driver turning right (who is usually required to stop and yield) is often unaware of my intention to do so until quite late in the process. A U-turn signal might reduce this conflict.

This could be implemented via one of the mechanisms linked, or by a scrolling LED message in the car's back window. Anyway, [marked-for-deletion] redundant.
