Hanging Roof Lights

1. Locate an electrical receptacle for the lights
   Plan to run heavy-duty extension cords from a working 120-volt electrical outlet that is protected by a ground fault circuit interrupter (GFCI). Ideally, use a switch-controlled outlet or plug the lights into an automatic timer that will turn them on at dusk and off late at night (but remember to turn the timer off when you won't be home). Both the receptacle's circuit and the timer must be rated to handle the combined amperes of all light strings connected to it. Do not use an indoor timer outdoors.
   
   
2. Measure the length of your home
   Use a measuring tape (30-feet or longer), measure the length of your house.
   
   
3. Test your lights
   Before you plug them in, check your strings, look for broken or missing bulbs and worn or defective wires. If you discover damaged wires, replace the entire string. If bulbs are broken or missing, replace the bulbs. To remove a broken or unlit bulb, use needle-nose pliers (pull mini-lights out; unscrew C-7 or C-9 bulbs). Once you have confirmed that the string is in good condition, unplug the string before replacing faulty bulbs, then check it again to be sure all lights work. If the string will not light, check it for a blown fuse (be sure to follow the manufacturer's directions). If the fuse has blown, replace it; if it blows again, replace the entire string.
   
   
4. Set up a ladder
   Place the ladder firmly on flat ground and lean it against the eaves, extend it well above the eaves and lean it at an angle that will be sturdy and safe to climb. Do not lean it against the gutter, it will not securely support the weight.
   
   
5. Hang the lights along roofline
   You want to hang lights without damaging your home's trim or walls. For attaching lights to gutters or the roof, use the appropriate plastic clips for the job.
   
   
6. Attach lights to trim
   For attaching lights to trim and other vertical surfaces, use omni light clips. Space them about 12 inches apart.
