Icicle lights are a style of Christmas decorations usually attached just below the roof gutters of a house. They evoke the image of an icicle, in that they hang down in staggered lengths from one long wire. The icicle style became popular in the 1990s, and while they haven't retained that popularity, people still decorate their houses with them. To use icicle lights, the idea is to hang them from a place where real icicles could form.
Decorating with Icicle Lights
Use a ladder to get up to the gutters of your house. Bring a hammer and some nails. Starting at one of the corners of your house and all the way around the roof perimeter, pound a nail a few inches below the gutters into the side of the house, every 12 to 15 inches.
Take the lights up to the first corner and begin to hang them on all the nails that you just pounded into your house. Depending on the size of your house, you'll probably need more than one package of icicle lights. But don't worry, the end of each icicle light wire has an outlet for extension. Make sure they're not actually plugged into an electricity source as you're hanging the lights.
Once you've decorated the perimeters of your roof with the icicle lights, plug them into a power source. The best way to do this is usually by plugging one end of the lights into an extension cord. Take the extension cord either to an outdoor or indoor electrical outlet, but use one that can be controlled by a light switch. When you turn the power on, the icicle lights will shine, making your house a winter wonderland.
