I'm led to believe that, even as soon as Christmas, the light display will show signs of deterioration unless meticulous maintenance (bulb changing, etc.) is done at least weekly.
Anyone taken a close look at the light bulbs themselves? Are they "mini-lights" with bulbs about a quarter inch in diameter by an inch long with filaments inside? Or are they LED's, whose bulbs are typically less than a quarter inch both ways? Or mid-size lights like the ones that outline the roofs and marquees on Main St?
Why I ask is that the mini-lights have the bad habit of going out in groups, which would leave dark streaks here and there on the castle. One burnout is not supposed to cause that but after four or five burnouts without replacement the string goes dark. Hardly anyone "fixes" them but rather entire strings of lights are typically thrown out when they go bad like that. Sometimes it is every other or every third light that goes out, depending on the wiring and then good lights have to be thrown out with the bad.
In my city (and many other cities) Christmas lights are strung in the trees downtown. It is not unusual for a section of tree trunk to be dark because a light string went bad, or more likely because some prankster stole a bulb. Removal of a bulb causes and entire string of mini-lights to go out.
