Traditional Mini Lights - These are the most commonly used lights for all occasions. But for Halloween you could get amber and purple to add a little pop of light and color to your decor. You can use them inside or outside. Light up your windows and add black silhouettes of cats and ghosts for a spooky effect.

Traditional C7 and C9 Lights - These are great for Halloween if you already have stringers for your Christmas lights. All you have to do is trade out the festive Christmas colors for opaque orange and purple. You can really use any combination of colors to fit your design. These are great for lining your house to show the spooks and ghouls to the door.
Have fun decorating for Halloween with any of these lighting options. Any of them would be perfect to fit to your spooky holiday decorations.
