The flashing lights on emergency vehicles which, when turned on, signal other cars to get out of the way. This term is most commonly used to refer to such lights on police cars, although it could be used for the same type of lights on ambulances or fire department vehicles.
So I was driving home, not noticing how fast I was going, and suddenly I saw those disco lights in my rear view mirror!
