The LED version of Lawn Lights is very durable and reliable. Well over 99% of Lawn Lights work perfectly upon arrival. For sets that worked and then went dark, we have found that the number one cause of the trouble is usually a severed wire. Most of the time, the severed wire is caused by a rodent (squirrel, chipmunk, rabbit, etc.) chewing through the wires. It is rare, but does happen from time to time. Fortunately, once the severed wire is found, it is usually very easily repairable.
In all cases, always inspect the entire length of the string for a severed wire. That is usually the cause of the trouble.
