New battery powered lights which can be used outdoors and come complete with a multi function controller and built in timer. Simply pop the batteries in and place either around the home or garden. When you turn the lights on for the first time a built in memory chip will recognise this and then each day automatically turn the lights on at the sametime for 6 hours and then off for 18 hours. It really is that simple. You also have the choice of 8 multi functions including static, slow fade and a merry flash! The battery compartment is fully weatherproof. Battery powered Christmas lights are a safe and hassle free way to light up your home this festive season.
