Last weekend, my family got to work decking the halls for Christmas. We didn’t test our strands of lights before we hung them on the house, and when we went to plug them in to make them light up, the strands on either end lit up, but the ones in the middle did not.

I had heard about a product called Light Keeper Pro from someone at a party. He raved about how this little gun fixed his lights and he didn’t need to go out and buy new strands. I thought this would be worth a try. The product costs $19.99, and if it worked, it would save me money in the long run. Most importantly, it would keep salvageable strings of lights and their connected garland from ending up as waste.

I ran to the store and bought the gun shaped tool with high hopes of pulling the trigger a few times and saving my strands of lights. I was completely ecstatic when I removed a bulb from one of the bad strands, pulled the trigger a few times, replaced the bulb and “viola!” the strand lit up. It was one of those “Castaway” moments where Tom Hanks yells, “I have made fire!”

Unfortunately, that’s where my success ended. The second broken strand will not re-light. I found two broken bulbs and replaced them. I used the voltage detector up and down the strand to make sure that juice was running all the way through. According to the voltage detector, it is. I used the alternate method of plugging the entire strand into the Light Keeper Pro. I’ve even checked to make sure each bulb socket lines up correctly. According to the instructions, and a few videos I’ve watched online (both on the product's website and on YouTube), I’ve done everything correctly and the strand should light up. But, it won’t.

I really wish I could praise this product because I’d have working lights and I’d be able to recommend something that will save you money and be sustainable. But, the best I can say is it may work; it may not work. So, here is my advice to you if you want to see if it works on your lights.

Ask your friends and family if anyone has one already and borrow it. That way, you can see if it works on your lights without having to put out the money.

Have you tried the Light Keeper Pro? What type of success have you had? I’d love to hear from those who have had success with it as well as those whose experience is similar to mine.
