We hung our Christmas lights on the house 2 nights ago, they worked fine then but aren't working now. It isn't just 1 strand it is the entire house. How do I make them work without getting all new ones?

Have you checked the outlet they are plugged into for power?

Have you checked your breaker panel for a breaker that has popped?

Can you give us more detail?

If you are plugging in to an outside receptacle, chances are that it is a GFCI. Check it and reset it. If this is the case, and it continues to trip, try separating some of the lights onto another outlet.
