Ok so ya know when ya need to use the bathroom but ya don't want to turn on the lights well this is just what you need. It is motion activated so when you walk past the sensor it starts to glow. You can set it to 1 color or to cycle thru the colors. The sensor is on a flexable arm that hooks over the edge of your toilet. Takes 3AAA batteries to operate. Everyone has some type of comment after seeing it for the first time! #Rankboosterreview #Sponsored #ADMOZ https://www.amazon.com/ADMOZ-Multi-Color-Motion-Sensor-Toilet/dp/B07C27Y8CK
