The city’s night reveals another face. As the clamor of day fades, light becomes the brush that paints this visage. Among the myriad urban light sources, neon lights, particularly authentic gas-glow neon (Neon), once defined countless classic city nightscapes with their unique charm – the vibrant atmosphere of Hong Kong’s Temple Street, the cybernetic pulse of Tokyo’s Shinjuku, the opulent dreamscape of Las Vegas. It was not merely a commercial cry but a visual manifesto of urban character, poetry flowing in the night, a symphony of light and shadow solidified on building facades. However, the essence of this light that once illuminated the city’s soul is being eroded, distorted, and even extinguished by the proliferation of cheap neon light strips.
