It's a light that shines into your toilet and projects a target as to where they should aim. Not only that, but the toilet target light is also a great idea for special needs children and autism spectrum kids. Not only is a cool way to help your toddlers learn to aim into the toilet while peeing, but it also acts as a toilet night-light to help guide you and your toddler to the toilet in the middle of the night. It is powered by 3 AA batteries (not included) and is super easy to remove and put back onto the toilet when they need replacing.Helps promote independent potty training for little boys and is actually loved by parents as it helps them clean up a whole lot less pee on the sides of the toilet and the ground.
