HONG KONG – For nearly a century, Hong Kong's iconic neon signs illuminated the night, contributing to the vibrancy of the cityscape after dark. An obsession of both local and visiting photographers, the signs were also a major source of inspiration for legendary director Wong Kar-wai, who used neon lighting to convey the mood of urban Hong Kong in many of his films.

Since the 2010s, many of the city's neon signs have been removed under tighter government regulations. Neon lights also represent outdated technology, wasting far more energy than modern LED signs. As a result, Hong Kong has seen a drastic decline in neon signage in recent years. Before too long, it may only be possible to enjoy the city's neon lights by watching old movies.

Now, Tai Kwun has collaborated with local NGO Tetra Neon Exchange to stage the exhibition Vital Signs, showcasing more than 20 neon signs of varying ages. As an art form, neon craftsmanship embodies the Hong Kong spirit of perseverance, and represents the city's unique visual identity. Through September 3, the show is not only a must-see for fans of Hong Kong history and culture, but should appeal to anyone who loves beautiful things.
