Specmsky LED Plug-in Night Light - Dimmable, 0.6W Adjustable Red Light with Dusk to Dawn Sensor for Hallway, Bedroom, Kitchen & Stairway - Energy Efficient Home Decor Lighting (4 Pack) - Perfect for Nighttime Safety & Cozy Ambiance

The light isn't motion activated, but it goes off instantly if you turn another light on, and it goes off instantly when you turn another light off. We have a bathroom with no window, but that room has also always served as 'the nightlight' because it is centrally located. With this little light of mine (:-)), it's bright enough so a person really doesn't even need to turn the main light on to use the bathroom, and it is just bright enough to be able to navigate around in the middle of the night. There is a slide at the top that adjusts the brightness (two levels), so if we DO need something brighter (like to use the bathroom), it's easy enough to just slide/click it over. Small enough so it's only using one outlet, I can flip it upside down in case I want the light but also want maybe need to use the top outlet for something else. My only 'con' would be that it's almost too sensitive to external light. One other room I had it in I had to move it closer to the window because the nightlight was turning on before I really needed it (yes, I could have pulled it out of the outlet, but that defeated the purpose of the dusk-to-dawn feature.)Certainly would consider it a good buy!
