The SnapPower SwitchLight for Double-gang light switches brings the convenience of the SnapPower GuideLight to the standard double-gang light switch. Remove your old switch covers and snap on the SwitchLight for beautiful lighting in seconds. Because light switches are typically higher on the wall than outlets, the downward shining light will illuminate a larger area and keep the light out of your eyes. This also keeps the night light out of the reach of children and it stays visible above furniture. Typical night lights shine upward and into your eyes. We included an adjustable switch so you can choose between bright, dim and off settings. This allows you to use the light for identifying your light switch or for use as a night light. The SwitchLight is perfect for use in Bathrooms, Kitchens, Hallways, Closets, and Bedrooms. This SwitchLight works great for single pole switches as well as 3-way switches (where an overhead light is controlled by two separate switches). PLEASE NOTE: The SwitchLights do not work on dimmer switches.
