The Lightkeeper Pro fixes most light sets and pre-lit trees in seconds. It finds the damaged bulb at the plug or at the bulb socket. The audible continuity detector pinpoints the problem by tracing the circuit to the point of interruption. Use the attached LED headlight to guide your way and let the 3-way bulb puller gets tight bulbs out with ease. Features a handy storage compartment built into the handle for housing your bulbs and fuses.

I found out about this tool by searching for "troubleshoot Christmas tree lights." I saw many hits about it and watched a couple YouTube videos (which I recommend to learn how to use it). I was amazed that it fixed a non-working section of my pre-lit tree on the first attempt! I had to go to three different stores to find one locally, and finally found them at Home Depot.
Pros: Good Size & Weight, Functional, works as described if you follow instructions, instructional videos on youtube
I never write reviews but this item warrants one! Been using it for years now. I've purchased them for friends and family, I've posted about it on Facebook. It has saved many prelit trees (mine as well as friends who have borrowed it), outdoor lights, prelit garlands, and numerous decorations. Totally worth it! If you follow the directions you can't go wrong. If your lights still don't work, then they just can't be fixed. This products will fix what can be fixed, but It can't fix something that is beyond repair.
We bought this during the after Christmas sale 3 years ago. It took me 2 years to fully understand how this thing works but it definitely does work. If you have a string that is not working just pull a bulb out and plug the socket into the spot provided on the tester and pull trigger repeatedly until the lights come on. If the string of lights are divided into sections make sure you unplug one of the bulbs that is in the non working section. Make sure the string is plugged in while doing this.
Pros: Excellent Quality, Functional, Well Made, Nice Design
What would have taken me hours in the past was cut to minutes with this tool. In the past it would be me and a volt meter going bulb by bulb trying to figure out why large sections of my pre lit tree would not work....now it is done in just minutes....make sure after the lights come back on you replace any dead ones or you will have more go out
I don't understand how u can't give this 5 stars. The directions are well written ans if you are confused than go on YouTube because it show you how to use all the options or go on their website. I had several light and other outside nativity set which I can't stand doing every year. All u need is time and 20 dollars. Really the only thing that this thing can't do is solve world hunger. My hats off to the person that thought of this the only problem is I whish I had this last year
This tool is amazing. I reserve that for only truly amazing products. My pre-lit tree had a bad string since we bought it at a clearance sale. I had wiggled and messed with every bulb and it still would not light. Using the tool I first discovered that every single bulb on the string was burned out. Not sure how but they were. I went through and replaced every bulb. The string still would not lite. I then did the shunt process which is as simple as plugging the tool into one of the sockets and pulling the trigger a few times. The string spring to life!! Turns out I still had 4 or 5 bad bulbs, went through and replaced them and the tree was perfect. A few minutes later another string went out. Plugged the tool into a socket again, pulled the trigger a few times and back to life it came. This thing is truly amazing!
Pros: Excellent Quality, Sturdy, Perfect Size, Functional, Lots of Features
I was so frustrated. Our pre-lit tree wasn't so lit anymore. I was going through it trying to find the bad bulbs, but couldn't find them. So, a drive to the Depot. Bought this, and brought it home, not expecting much. It worked perfectly. I had so many dead bulbs, but it found them all. Got some going again, also. Worked just as described.
Saved me from having to try to string new lights on a pre-lit tree.
For $20 and the Home Depot return policy, this is a no brainer. I had, yes now it is working, a GE 150 Pro Line light set with 2 of the 3 sections unlit. I tried the quick fix method as described in the instructions and got 1 working, so now 2 of the three worked. The 3 section did not respond to the quick fix. Using the audible tone procedure, I found the bad bulb and now have 150 lights working. A replacement is $18.98, so the device, after 1 repair cost me $1. The next set will start to save me actual money.
I did contact the company for assistance and they responded quickly and professionally.
This is a great product and a great company.
Go buy one now!.
Pros: Excellent Quality, Well Made, Lots of Features, Nice Design, it actually works!
This product works great! I was able to use it to fix a burnt out section of lights on the house by plugging it into the dead section and pulling the trigger once! It also made a nearly impossible job possible in a string of lights that had a huge burnt out section. Using this product by pulling the trigger 4 times, I was able to restore the burnt out section and identify about a dozen burnt out lights! It would have been impossible to identify the burnt out bulbs without this. This product will pay for itself very quickly, thus great value!
As much as I would have loved for this to work, it simply didn’t. I had about ten strands of lights that had sections burned out, but had no bulbs missing. I tried it on every strand, including one net light, but unfortunately, nothing happened. I am not sure if this only works for a single row of bulbs, but I will tell you it does not work on curtain or net lighting. The other problem that you will have is because you have to plug in the lights to do this, you will get shocked on any bulb that is broken. Once the feeling in my fingers comes back, I am returning this to the Home Depot.
This inexpensive product ($20) is a model of thoughtful product quality. The instructions are clear and complete with good explanations of the electrical principals involved. It works. And even the simple packaging is well designed to house the tool, spare bulbs, and also the trifold instructions card for storage. That's amazing --- in today’s world of sloppy work --- that a company could care enough about their product to think all the way through the user experience process. Well done.
Installed multiple strands of lights totaling upwards of 5000 lights on my front bushes. All the sets were brand new and all were plugged in and checked before installed. Wired them all up and turned them all on and 2 sets were half out. Awesome. Saw the tester in the store so i picked up. Skimmed over the instructions and headed out front. Had both sets fixed and lit in a minute and a half. Bottom line, if you get into holiday lighting, this tester should be on a shelf in the garage because it will save the day when your lights decide to act up.
Well worth the money. Not totally sure how it all works but I have a prelit tree and four of the strands were only partially lit. I was prepared to just add new lights when i found this on line. I got in the car a drove to the store immediately. I had every strand but one working in less than five minutes. The one strand i still ended up going bulb by bulb to find the bad connection. The voltage detector was hard to use on the prewired tree because all the wires are so close together. One other suggestion would be to pick up extra bulbs while you are at the store to replace any that are bad. I can see using it for other low voltage projects too.
I've had one of these Christmas tree light tester/repairer guns for years. This was a replacement. I have fixed many strings of lights with this tool. Saves hours of time trying to find the bad bulb in a series wired string of lights. Pull one bulb out and pull the trigger until the lights come back on. Disconnect and put the bulb back in. Probably works 90% of the time.
Pros: Easy to Assemble, Easy to Install, Good Size & Weight, Functional, Lots of Features
John De Cosmo has produced a product that does exactly as claimed. I salvaged a rope light bundle with 500 bulbs and three other light strings .It restored the shunts and identified where there was a broken light bulb. I grant that this product takes a bit of understanding but the instructions are clear even if you have to persevere a bit. To begin I could not get the continuous beep to operate, the intermittent one did work immediately, but then it did and I was able to isolate the problem. The bulb extraction portion is basic: it works but with some effort and when the bulb comes out it shoots out. The individual bulb tester works perfectly. This is not a precision Swiss instrument which would cost three times as much but for the price it works well: hence the five stars which I rarely award.
As this product is basically a Christmas tree light tester I would recommend storing it after the holidays by taking the batteries, supplied, out until next holidays.
Pros: Good Size & Weight, Functional, Lots of Features, Comfortable, Nice Design, informative instructions, spare bulbs and fuses supplied, does the job, comes with batteries installed
Cons: bulb extraction portion a bit difficult to use
This tool is true Christmas Magic. We had two strands on a pre-lit tree that weren't working. Plugged the strand into the tool, pressed the trigger and POOF! the lights suddenly came on and stayed on. I hope this tool works as well and easily for you as it did for us.
We bought this tool after discovering that our pre-lit Christmas tree had multiple strands out... again. We had already restrung several strands of lights in multiple previous years and were irritated at the thought of having to do it again (after all, isn't the main reason you buy a pre-lit tree to NOT have to string the lights every year). We were about ready to throw out our $300+ tree when I discovered this tool. The tool offers two different options for fixing the lights. The first "quick" option didn't work in our case, but we were pretty easily able to determine the location of the faulty bulb using the audible voltage detector. It was a little tricky because lights from different parts of the strand were intermingled because we left the strand wound around all the branches. But the company's website has several very helpful videos that help you figure it out without having to unwind the lights. If we never use this tool again we've already gotten our money's worth!
I was skeptical when I first saw this but went back and purchased it. I works as advertised and I have fixed 2 strings of icicle lights as well as a couple of regular strings. I do not know if it will work on Leds which I am gradually using to replace the traditional lights.
