Neon street signage became a defining feature of Hong Kong from roughly the 1950s onward, as businesses competed for attention in densely packed commercial neighborhoods. At its peak the city was home to thousands of hand-shaped glass tube signs, many of them large enough to span entire building fronts. The tradition was particularly concentrated in areas of Kowloon, where narrow streets amplified the effect. In recent decades, many of the older signs have come down due to safety regulations and the rise of LED alternatives, making the surviving streetscapes increasingly rare and widely documented as a form of urban heritage.

The neon glow is richest on a rainy evening, when wet streets double every color and the mist turns each light into something closer to a bloom than a beam.
