If you need to visually inspect your Christmas lights to determine which are good and which need replacement, there are a few things to look for. First, look for discoloration, such as a dark spot or two on the inside of the glass. The spot is an indication of a burnt filament. Also, look for missing filaments, cracked bulb glass, and broken sockets.

Blinker lights come with a standard box of Christmas lights, so you don’t need to pay extra for them unless you’ve misplaced the ones from the original box. You can buy replacement Christmas blinker lights for about $8 per box. If you want to plan for future holidays, you can buy a value box of 24 replacement blinker bulbs for about $12. Also called flasher lights, the replacement bulbs often come in packages of six bulbs.

Using a staple gun to hang Christmas lights on your roof or shingles is not recommended. Puncturing your roof with staples can cause damage, leading to cracks, leaks, and exposure to the elements. Staples are also less reliable than other methods like roof clips. For a safer alternative that won't damage your roof, use shingle tabs.

For a 7-foot-tall column, choose a light strand that is at least 32 feet long. You’ll also need to measure the distance from the column to the closest outlet to get outdoor extension cords that are the right length.
