Outdoor Christmas lights cost between $80 to $300 on average without installation. This comes out to about $4 to $50 per strand. You can get a box of outdoor Christmas lights for as little as $20, if you just want to decorate a small area, like a doorway. If you want to go all out and cover your entire home, you'll need between 10 to 20 strands of 100 to 200 bulbs each.

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.

You can attach Christmas lights to your palm tree by securely wrapping the strings around the tree. If you notice the strands slipping, you can also use a staple gun to secure them to the trunk.

It's safe to hang Christmas lights from gutters with a few considerations. First, when installing the lights, follow safe ladder-use guidelines and avoid getting onto the roof. Second, for best results and the integrity of your lights, use clips to keep the bulbs away from inside the gutters where they could run into trouble with water or ice.
