If you only need strands in safe and easy-to-reach locations and are sure of your electrical system, you can probably purchase and install lights yourself. To do this, carefully test your outlets to ensure there aren’t any sparks or other concerning issues. Your budget might also influence this decision, as going the DIY route can be significantly cheaper.

First of all, don’t shop for bargain lights—often, you’ll end up with a faulty or broken strand, full of dead bulbs or less-than-luminous brightness. Choose quality lights that will last you many years—LED lights have been known to last as long as 100,000 hours. Second, plan ahead and purchase lights for next year’s Christmas during this year’s post-holiday sales. Finally, have a vision and a plan—if you know the measurements of your home, including any windows, doors, and outside bushes you wish to light up, you should be able to only purchase the necessary lights and not more than you need.

Most contractors will include removal of your lights in the price of installation, but it’s always a good idea to double check. Storage of the lights is often also part of the package when you hire an installation professional, since you might choose to use the same lights for several years.

Christmas lights typically do not need to be grounded like electrical circuits in your home do. However, it's crucial to use outdoor outlets equipped with ground fault circuit interrupters (GFCIs) for added safety. GFCIs can help protect against electrical shocks and are recommended for outdoor electrical connections when using Christmas lights.
