Unicom Security Timer Offering a simple yet effective way to protect your home, this security timer works by switching your lights on and off in a random pattern to make your home look occupied when you're away. It's designed with a clever dusk to dawn sensor and winter/summer settings to ensure it only lights up in hours of darkness. It's easy to set up and there's no programming required - simply plug the timer into a wall socket, then plug in the lamp. Dimensions: H10 x W6 x D6.4cm Colour: White
