By Sarah Jenkins
From bimetallic automotive relays to racehorse hoods and smartphone memes, the word "blinker" highlights how technical tools drift through pop culture. A device invented to keep road travelers from colliding has morphed into shop floor comedy, precision acoustic design, and youth vocabulary.
