To my surprise there were no such products readily available. I did later on find some online, but who wants to wait? When you can build one yourself cheap and easy!

I found a site that detailed exactly what I wanted to do. I followed their directions to the letter.

You need a basic dimmer switch, probably around $6, a short household extension cord $1.50, and an electrical box, these are about 45 cents. You will also need 2 wire nuts,  I already had those,  but will only cost you a few cents if you need to buy some.

Basically you want to spice the dimmer between one of the wires on your new extension cord and enclose the wiring inside the box.

It took only about 5 minutes of "wiring" it was done and worked just as I had imagined.

The other bonus to having your lights running at a dimmed level is it increases the life of your lights, and saves you some $ on electricity!

Want to make one too? Check out this site for the directions that I followed.
