My 19 year old son just told me about this cool electronic gadget you can buy that you attach or aim at nonworking light bulbs on a strand of Christmas lights. It analyzes and finds the burned out bulb. I looked at one at QVC. You have to aim the tool at each light, and it lets you know which is not working.
The tool costs $15.92 plus 3.97 shipping and handling. And not only that, but then I'd have to actually use it!! Yeah right!
I think I'll go buy me another set of $2.99 lights from Wal-Mart.
