Turn signal sounds come from the small relay or electronic module that makes a car's indicators flash, producing the tick drivers hear in the cabin. Corolla models are among the most common cars worldwide, so this particular clicking rhythm is familiar to many passengers and drivers. Recordings like this circulate on soundboards because they are instantly understood without context: a turn is coming, the car is waiting, or traffic is paused. Editors reuse the clip for memes, driving footage and simulation projects where a generic indicator sound would feel less specific.
