I have a hallway which had a very inconveniently placed light switch. There
are two steps followed by one step and in the dark, I'd trip over the steps
trying to find the light switch. Put in a motion-detecting wall-mount
device. When the light is on, AM radio suffers.
A Braun electric toothbrush charge here puts out garbage, especially when it
is charging the brush. The charger couples to the toothbrush inductively.
