Night lights have a long history and in modern times they are used all over the world to provide a measure of light during the night time hours. Night lights have always been regarded as a source of darkness and of light, both of them serving as a signal of comfort, safety, and security to both children and adults. Night lights provide a soft and gentle light that helps with safety in our homes at night. Placing a nightlight in the bedroom or hallway will provide a low light and allow the person to easily find their way around in the dark. It also works to ward off potential intruders, who are less likely to break into a home that is lit up. Night lights come in a variety of shapes, sizes and colours — from the traditional night light to the trendy LED lights. Some even have a built in motion sensor to turn the light on or off when movement is detected. With the advancement of technology, they can even be programmed to come one when it is dark and turn off during daylight hours. There also exist special night lights that are more energy efficient. These can last for up to 50,000 hours and are extremely affordable to purchase. These types of night lights are great for those that are looking for an ecofriendly way to light up their homes. Night lights are not only functional but can also serve as decorative accents in any room. They can be an excellent addition to any bedroom, hallway, bathroom, or kitchen, adding a warmth and inviting feeling to the environment. Night lights help us to transition into sleep at night, providing a feeling of safety and comfort all throughout the home.
