I remember on the old 1950's era TV shows, they used to have the little
signs that swung out and said "STOP", "SLOW" "GO" etc. I can't tell you how
often I've been heading towards a light in the evening or the early morning,
with the sun behind it, and been completely blinded. Seems to me that the
signs would solve that problem -- even if you can't read what it says, you
can tell if its-in-the top (red) or bottom.
