Christmas light bulb tester

I use this product to quickly find defective light bulbs in my Christmas light chain. This saved me hours trying to determine which light is bad or where the break in the line is. I liked it so much I bought my dad a second one.

Pros
  • Easy installation
Cons
  • Everything is fine
