Night lights, small but powerful, have been lighting up peoples dreams for centuries. They can come in all shapes, sizes and colours, providing a comforting source of illumination in the darkness. Night lights provide a soothing influence as they give off a gentle glow that fills the room, allowing children and adults to feel safe and secure before drifting off to sleep. The choice of colours they have can also be used to improve mood, as different hues bring about different emotions. For example, a bright pink or yellow will help wake up children in the morning and is said to be inspirational. Night lights also have practical applications for the adults they help throughout the night. For those who have to stumble around in the darkness without lights, night lights are indispensable. Such lights can also help those who are elderly or suffer from poor eyesight. Night lights are now used more than ever, from Christmas decorations to creating a homely atmosphere. Even in the era of electricity, people still make use of night lights to create an ambient and pleasing atmosphere for any time of the day. Night lights will never go out of fashion. They provide warmth, comfort, security and a pleasant atmosphere that can help us to relax and make the most of the night.
