One of the most elaborate displays can be found at Callaway Gardens in Pine Mountain, Georgia where 1.5 million tiny lights trace fanciful outlines of Christmas characters and winter scenes in trees and along several miles of park roads.
Visitors can view the display in their own cars or in the park's trams.
It takes five weeks to install the lights for the show, which is expected to draw more than 300,000 visitors during this, its fourth season. In case you can't make the trip this season, here's a sample of what you're missing. External sites are not endorsed by CNN Interactive.
