The toilet night light will help you go to the bathroom in the middle of the night without having to "fully wake up" by helping you see the way to the toilet via a green or red light. No longer will you have to pee sitting down at night because you can't see the toilet. No longer will you accidentaly fall in the toilet because someone left the toilet seat up because they were puking all night, such disasters will be avoided all thanks to the toilet night light. The toilet night light attaches right to the bottom of your toilet seat with adhesive tape, and will turn on when it senses someone coming near it. The toilet light uses 2 AA batteries which are not included.
