Eufy Lumi 3-Pack Motion-Sensing Night Lights | $12 | Amazon
Anker makes night lights, and they don’t even have to be plugged into a wall. You just stick them anywhere, and they turn on when it’s a) dark enough and b) when they detect motion. This week on Amazon, you can get three of them for $12, down from the usual $15.
Just note that they run for up to a year on three AAA batteries each (not included), so you’ll want to pick up some rechargeables.
