Christmas, Hanukah, and other festivals of lights benefit from lots of decorations. Unfortunately, when everything is unpacked each year, lights may not work. Fortunately, many can easily be fixed. Here's how.

How Does It Work?

Holiday lights are strings of low-wattage light bulbs that are designed to decorate an indoor holiday tree, the outside of a home, a fireplace mantle, a stairway, or anywhere else a homeowner wishes to add light and color.

What Can Go Wrong?

Holiday lights are relatively simple in operation, so the things that can go wrong typically are just as simple. Whole light strings may not glow and single bulbs may burn out.

Fix-It Tip

Bulb blown out? Don't throw away the bulb you think has caused a problem until you retest the string. The bulb may still be good.
