When it is time for you to go to bed, do you like to have a night light shining? Some do, especially young ones, but even adults appreciate night lights since they can help them find their way if they need to get up in the middle of the night for some reason. If you are shopping for a night light, it is important to remember that not all lights are made the same. If you buy a really cheap night light, you might end up with a fire hazard on your hands.
You should also be aware of what functionality you are looking for. Do you just want an accent light or a light bright enough to see well? Do you want the light to be on all night or only when it notices movement?
There are so many different options out there, so the more specific you are in your criteria, the more likely you are to get the light that is just right for you.
