While some people like to leave the Christmas lights on all night for Santa, local firefighters say there are safety reasons to not do so. It's may be a safety issue.
Video from the U.S. Fire Administration website shows how fast a dry tree can go up in flames from hot Christmas lights.
Firefighters say some people run their lights all night Christmas Eve and into the Christmas Day. That can start a fire outside or inside your home.
"They do tend to put off heat. We recommend you don't strand more than three lights together at one time. If you do, they'll put off even more heat. Three per strip per outlet is recommended," says Lt. Robert Thomas, Waynesboro Fire Department.
Firefighters say if you are going to run lights for a long period of time Tuesday, make sure your tree has been watered and hasn't dried out.
