There are probably more neon signs in Hong Kong than there are lamp posts. If not true in all of Hong Kong, it is definitely true in the popular shopping areas like Mongkok, Tsim Sha Tsui, and Causeway Bay. Here is a list of pages with photos of neon signs:

• Mongkok
• Causeway Bay
• Tsim Sha Tsui
• Percival Street
• Nathan Road
• Nathan Road neon signs
• Sai Yeung Choi Street South
• Mongkok neon signs

Then of course, these views still can't compare with that from Victoria Peak.
