This handy and inexpensive tool will extend the life of your Christmas lights and has fixed my lights year after year.

It was so frustrating this year to pull our Christmas tree lights out of the box and find that 4 of them were only halfway working. FOUR!

What do they do in the box all year while they sit there, that would make them go bad? And why does only half the strand of lights not work, while the rest work just fine?

Chances are very high that you will run into this problem too, or already can remember going out and buying new lights last year because half of them seemed to be broken.

Well, to be 100% honest, it was my wife who solved this problem by bringing home a Light Keeper Pro for me to try on the lights. Sure enough, the first attempt on the first strand I tried (the one that was on our fully decorated tree) was fixed by this handy device.

How does it work? It turns out that one of the most common causes of light set failure is a malfunctioning bulb “shunt”, that can be cleared by being zapped with a slight electrical pulse. I have no idea what a shunt is (I’m not an electrician) but the Light Keeper designers sure do, and it really does work.

Here’s a video of me fixing a strand of lights using the Light Keeper:

Not all light strands have misbehaving shunts though – some just plain have bad bulbs, which is another thing the Light Keeper can check for. It has the ability to sense voltage through each bulb just by pointing it each bulb.

If the tester beeps, then the bulb has electricity flowing through it. If it doesn’t beep, then the bulb is bad and needs to be replaced, which was the problem for the second strand of lights I fixed. Two down and 2 more to go, and that’s 4 strands that I won’t have to toss in the garbage can.

So go order a Light Keeper, save money by not having to buy new tree lights… and impress your family with your new secret weapon year after year!

    I’m not an electrician, but I guess this thing is based on a common indicator, such as electricians usually use. It’s just put into some kind of a consumer friendly form, so that anyone could use it at home. But anyway, this thing must be very useful at these Christmas times when we all are taking out of boxes our good old Christmas Tree lights ๐Ÿ˜‰

    A shunt is a wire that
    A shunt is a wire that allows electricity to flow across the bulb in case the bulb filament burns out. This enables the circuit to complete, and the rest of the bulb to stay lit.

    Hard to tell what this thing is actually doing without having one in my hand.

    THIS TOOL DOES WORK!!
    I have one of these tools for fixing christmas lights. I bought it years ago and it was the best investment I ever spent money on. This thing has saved me so much time and work. If you can find one, buy one! I found mine in a craft store. I don’t know if there are different brands out there as you don’t see them all over the place. But I know mine works and it has lasted for years! There’s nothing worse then getting all the lights (that were working) up on the house or the tree just to have them go out. I used this tool and fixed the whole strand in a few minutes. Worth ever cent!!
