Night Lights, a traditional custom of lights, has become an indispensable part of our life. In old times, people used lighting to provide a source of night light and to indicate the nightfall and the arrival of dawn. Nowadays, even though many countries may have already entered electric grid, the custom of night lights still exists, with its function evolving from one of practical use to a symbol of reunion and romance. Nightlights were used in many western countries since the middle Ages, often in the form of traditional oil lamps. The romantic flickering of the light carries people back to the scene of medieval villages in the old times, when family and friends gathered around a warm light in the middle of a cold dark night. In Asia, nightlights are for visitors, as it is believed that special lights will guide those who are away from home “back to the simple way”. In some places, people tie red ribbons or strings on the lamp, as a symbol of reunion between family members. Also to symbolize reunion and love is the use of neon night lights. Whether the classic red neon signs or the colored billboard, those night lights bring a feeling of security at night and work to ward off the darkness. No matter what form they take, nightlights are always a source of joy and it bring a special atmosphere to the night. Just light the lamp and enjoy the warmth and love of the night.
