Have you noticed a parade of fire engines, police cars, ladder trucks, and other first responder vehicles winding their way through Seattle neighborhoods on Friday nights? Don’t be alarmed, it’s Seattle Fire Department, teaming up with Seattle Police Department, for Friday Night Lights. They’re driving engines and ladder trucks through residential streets to let you know they are here to serve. Residents can come to the window, porch, balcony, or front lawn to check out the “light show.”
