1. Use outdoor-rated gear only

Bob Vila says to use only outdoor-rated lights, extension cords and power strips, and warns that indoor-rated devices outdoors can cause short circuits, an electric shock or a fire hazard. Illinois Extension suggests looking for certification from an accredited lab such as Underwriters Laboratories. Check the label on every strand: some are indoor-only (Public Storage).

2. Plan your power

• GFCI outlet. Illinois Extension, Idaho Power and South Carolina's fire safety program say to plug outdoor lights into a GFCI-protected outlet.
• Older homes. Bob Vila says outdoor outlets in older homes may not be weather-resistant, and suggests replacing them with modern outlets that follow National Electrical Code guidelines. A licensed electrician should do that work.
• Cords. Keep outdoor connectors above ground and out of snow or water, and do not plug extension cords into one another (South Carolina). Keep cords out of walkways (Idaho Power).
• Strand limits. Only connect as many strands as the maker allows. Use the calculator's power check.
• Remote switch or timer. Family Handyman suggests a remote-controlled switch plugged into an outdoor outlet so you can turn lights on and off from inside or from your car. Illinois Extension says to turn lights off before sleeping or leaving, or time them.
• No outlet nearby? Bob Vila says battery or solar strands are options. See solar Christmas lights.

3. Choose your day

LeafFilter notes that hanging in wind or ice raises fall risk. Ware Landscaping says adhesive clips need surface temperatures above roughly 50°F to bond, and suggests putting clips up in October or early November in the Chicago area. Hanging lights in late fall, before the cold, is our own suggestion.

4. Attach the lights

• Roof and gutters: see gutters, no gutters and gutter guards.
• Walls: see no-nails options and stucco.
• Soffit or fascia: Family Handyman suggests clothespins clipped to the bottom lip of the soffit or fascia to avoid holes. It warns this may not hold in windy spots, heavy snow or where squirrels are active.
• Banisters and fences: Family Handyman says zip ties string lights on banisters and fences without marring the surface.
• Patio string lights: Bob Vila says strands come in lengths between 25 and 150 feet, to mount them on a taut wire so they do not sag, and to test every strand before hanging.

Common questions

Can I use indoor lights outside?

No, not unless the label says they are rated for outdoor use. Bob Vila says indoor-rated devices outdoors can cause short circuits, electric shock or a fire hazard.

How do I power lights if there is no outlet?

Bob Vila says battery or solar strands are options. Another route is a new outdoor outlet installed by a licensed electrician.

When should I put lights up outside?

On a dry, calm day (LeafFilter notes wind and ice raise fall risk). If you use adhesive clips, Ware Landscaping says surfaces need to be above roughly 50°F, so earlier in the fall can be easier.
