Night lights, also known as dream lights, are a type of plug-in children's nightlight that have become a staple in many bedrooms. They are made with calming plastic shells and colorful light fixtures that provide just enough light to make children feel safe and relaxed in the dark. The lights have a number of different designs and settings, allowing children to choose one that fits their individual needs. The designs can be adjusted to project light around the room, giving the entire bedroom a subtle glow. This allows children to look around without feeling too exposed and can be calming for children who might feel uneasy in the dark. Other night lights are designed to project a number of characters from popular shows on the walls and ceiling. This provides children with a sense of security in their surroundings, making them feel more relaxed. Night lights are also helpful for children who may be afraid of the dark. Most night lights come with a timer that can be set to turn off after a certain amount of time, which can help children feel more comfortable in the dark. The lights can also be used to gently guide children to the bathroom if they need to get up at night. In short, night lights can create a soothing atmosphere for children who need extra help feeling safe and comfortable in the dark. They provide just enough light without overwhelming a child's senses, allowing them to drift off to sleep in a calming environment.
