A neon light board is an illuminated display board that uses neon gas to emit light. Neon signs have been popular for decades and are often associated with vintage or retro aesthetics. The gas inside the neon tubes is excited by an electric current, causing it to emit light in a bright and striking way. Neon light boards can be used for advertising or decoration and are available in a variety of shapes, colors, and designs. They are typically durable and long-lasting, making them a popular choice for businesses and homes alike.
