Night lights are one of the most beloved pieces of modern technology. They are such a simple and ubiquitous piece of household technology that they might be taken for granted, yet they have a profound impact on the quality of one's everyday life. The most obvious impact of night lights is providing a comfortable level of light when going to the bathroom or getting fresh water at night. No more fumbling in the dark, trying not to wake up the household! There is a sense of security that comes with seeing that familiar night light in the hallway. But there are other subtle impacts of night lights that may not be immediately apparent. Nightlights also serve a psychological purpose, providing a feeling of safety and comfort to those who might otherwise be fearful of the dark. Not only that, but they can also help promote a good night's sleep, as a nightlight provides just enough light to prevent a person from being completely in the dark. Finally, night lights can also add a bit of quintessential cute to a room or hallway. It really does make a house feel like a home, as the colorful designs of most night lights help to invoke a sense of cheer and home-like comfort. All in all, night lights are a brilliant and invaluable piece of technology. They provide a feeling of security and comfort, while also adding a bit of charm to any room. Next time you switch on your night light, take a moment to appreciate its importance.
