The Uni-Com Plug-through Colour Change Night Light automatically switches on when it gets dark, and off when daylight returns. You can choose a white, blue or pink light and the plug-through feature means the mains socket can be used for other appliances. Ideal for bedrooms, hallways and use all around the home, providing reassuring comfort and safety. Simple to use, just plug it into a 13A mains socket, switch the power on and turn the front dial to select the colour required. The 9 long life LEDS are only illuminated during hours of darkness, meaning very low power consumption.
