We like our bedroom dark when we sleep. When we go in the bathroom or down the stairs we don't want to wake each other turning on all kinds of lights. We didn't want a full time night light. We found a great solution with Ecopa Nicera model SL603 battery powered motion sensing lights. They only activate in the dark with motion, attach easily with two way tape, and can be aimed where the light is needed. I took the light-sensor out of the holders during travel because I wasn't sure how they would withstand California's interstates. These lights just work great!
