Not a bad idea here. No wires or batteries to worry about. Just screws into any ceiling-mounted light socket like a standard light bulb. It can’t be used in a lamp with a lampshade, but you wouldn’t want to uses it there anyway. Testing is as easy as flipping the light switch twice and twice again to turn off. You can also put a light bulb in it so it acts a light source as well…
