    LED stands for “light-emitting diode” and are often used as indicator lights (such as in aviation or automobiles) although they’ve become increasinly common in recent years as general lighting. Advantages over regular lighting include lower energy usage and thus longer life, plus greater durability and reliability and smaller size.
