These red and white led icicle lights are perfect for round the front of your home as long as the transformer is kept indoors and they are on white cable to give them a frosty feel. Led lights are very bright, low voltage and energy efficient to save you pennies on those ever rising energy bills. The lights have a speed box which can make the settings faster and slower. The lights set is a total of 11m with an extra 10m of lead wire. The set is operated with a 24v transformer.
