The SMiLE Switch's happy face and nose "switch" alone will brighten up any room. Battery operated so there is no need for an outlet, giving you the freedom to place anywhere. Simply attach the SMiLE Switch to the wall with the included Velcro strip. Turn the nose "on" and the LEDs will emit a soft yellow light. Peel the light off when you want to take the light with you. It is that easy. Perfect as a nightlight, in the bathroom, entryway or hallway!
