You can never say it enough! Remind them each night at bedtime with charming artwork from Yellow Button Studio. The night light base is mounted through the canvas-covered wood frame and swivels so it can be positioned to work with any U.S. outlet layout. A 4-watt bulb is included. The on/off switch ensures that a soft light is shining only when you want it. These night lights have passed independent laboratory safety tests and meet all CPSIA guidelines.
