Right now it's nighttime and there's a utility company truck parked on the street in front of our house with spinning yellow lights. What are they called?
Like at Kmart in the 1980's they would announce a "blue light special" then start spinning a BLUE light of the same type. So if it wasn't for that, I would call it an "emergency light," but I just don't know.
