Neon signs are luminous, eye-catching signs that utilise electrified glass tubes filled with neon gas to produce vibrant, colourful light. These signs are known for their distinctive retro aesthetics and have been used for decades to attract attention and promote businesses. Neon signs work by applying a high-voltage electrical current to the gas inside the tubes, causing it to emit light. The tubes are shaped to form letters, shapes, or logos, creating visually appealing and customizable signage. Neon signs offer versatility in terms of design, colour, and animation, making them a popular choice for businesses, bars, restaurants and other establishments seeking to make a high-impact on their target audience.
