I have a tiny set of Christmas lights on a wreath. One end has the male plug and the other end of the female but they have only 2 prongs and a regular extension cord will not "fit" the string of lights because it has the wider prong on it. How can I attach the lights to an extension cord?

Pick up an adapter to convert your extension cord from three prong to two prong. They are available at any big box type store in the electrical dept.

Must be an older extension. All new 2 prong are polarized with large and small slot. You could also put a small prong male plug, you can still get them.
