The LED Stair lights are something that I didn't even realize that I needed. They provided the prefect amount of light so you won't trip in the night but are not to blinding. They take 3 AA batteries and just stick to the wall via double sided tape. They turn on only when something walks by. And if your like my family, who have several dogs, your stairs will become an awesome light show in the middle of the night. I definitely will get more of these and will recommend this to my friends.
