PIR Closestool Lamp

As a father, I want to share an experience with u ...

My son is four years old, he is able to go to toilet by himself.

But he is not able to turn on the toilet light, so I still need to go to the toilet with him.

Finally I solve this problem but installing a battery powered PIR lamp in closestool...

the lamp itself can adjust many things include the duration of the lighting...
