She is known to inhabit rivers, lakes, and streams, enchanting those who come near with her mesmerizing songs. In some tales, Nixies are friendly and helpful, while in others, they can be mischievous or even dangerous, luring people into the water. In modern times, the term "Nixie" has also been used to describe a type of vintage electronic display known as a Nixie tube. These tubes glow with a warm, orange light and were commonly used in old clocks and calculators, showcasing numbers in a unique and nostalgic way.
