Neon lights are luminous tubes filled with inert gases, primarily neon or argon. When a high voltage is applied, electrons in the gas atoms become energized, jumping to higher energy levels. As these electrons return to their original states, they emit photons, producing the characteristic glow. Neon emits a red-orange hue, while other gases yield different colors. The tubes' shapes and coatings contribute to diverse visual effects. First introduced in the early 20th century, neon lights gained popularity for signage and artistic expression, symbolizing both commercial allure and cultural vibrancy. Their enduring appeal lies in their mesmerizing, vivid illumination and artistic versatility.
