Neon lights are bright, colorful lights created by passing electricity through gas-filled tubes. The gas, usually neon, emits a vibrant glow when energized. These lights are commonly used for signs, decorations, and artistic displays, making them popular in urban environments. The invention of neon lights dates back to the early 20th century, with Georges Claude being a key figure in their development. Neon signs became iconic in cities like Las Vegas and New York, where they illuminate streets and attract attention. Their unique colors and designs contribute to the visual appeal of nightlife and commercial areas.
