Automatic light switch
Install a motion detector to automatically turn the light on in the toilet or storage area when you enter the room. The light will go off when it detects there is no longer any movement.
Make your life more comfortable
Automatic lighting is all about making your life safer and more comfortable. Arrange for: a dimmed orientation light to come on if you get up in the middle of the night; the stairwell light to automatically switch on at sunset and off again at sunrise; your garden lighting to come on when it gets dark; and for the light next to your bed to slowly wake you up with progressively brighter intensity.
