The neon lights were a word to describe a deserted scene with sparse lights. Neon lights were a type of cold negative gas discharge lamp that emitted light through an energized glass tube or bulb filled with a thin neon gas or other rare gases. We can see this word being mentioned in the movie "The Lights Are Out". The movie told the story of a middle-aged widowed Mika who discovered her husband's secret neon factory after his death and rebuilt a classic neon sign with her husband's apprentice. The film was set in Hong Kong's unique neon lights and explored the beauty and struggle behind keeping the neon lights alive. In addition, neon lights were also described as once dazzling, but now they had become dull and sad elements. Therefore, the bright neon lights could be understood as an image full of emotions and memories of the glorious moments of the past.
