Invented by an Australian engineer and trademarked as "LED Bails", they were designed to aid umpires with both run-out and stumping decisions as well as provide distinctive images to television coverage during day-night matches.
LED stumps were first used at the 2014 ICC World T20, and have since become commonplace in major white-ball matches like ODIs or franchise T20 leagues.
