We all like Christmas lights, but right now is NOT a good time to climb on your roof, with all the ice and snow.
The Consumer Product Safety Commission says around 15,000 people wound up in a hospital emergency room from injuries related to Christmas decorations.
Some were even killed.
They say there are lots of Christmas tree fires, too.
The CPSC says 33-percent of the injuries were from falls, 11-percent were cuts, 10-percent backstrains and the rest fall under the miscellaneous category.
And they say the number of injuries has gone UP during the past few years, not down, so be careful.
