We do not recommend or advise using our Ice Lites outside – neither the complete pre-assembled light sets or the separate Ice Lite covers you may have placed over bulbs you already own.
Since the Ice Lite "covers" are hollow and simply fit around the base of the bulb, they could easily accumulate water from rain or other precipitation inside and cause problems.
As such, this is an indoor-only product and looks great on Christmas trees, mantles, or tablescapes – basically anywhere you want a charming "lit ice" like effect!
