LED Keeper® - LED Holiday Light Set Repair Tool

Love this product! Saved me from throwing away my LED Christmas lights strand. I was able to locate the faulty led light bulbs and replace them. Voilà, lights are working again. Highly recommend this if you want to save money from having to buying more light sets!

I had two outdoor reindeer that had partial LED light strands out. I monkeyed around with a voltage tester, voltameter and randomly swapping out lights to try and find the culprit for hours - to no avail. I bought this in hopes of salvaging the reindeer or not having to rerun new light strands. After 15 mins, I found the 3 dead bulbs and the reindeer are as good as new. Save yourself the trouble and just buy this tool. Specifically for pre-lit trees/decorations, the probes on a voltameter are almost impossible to insert and get lined up on both sides of the terminal with such little room, the voltage tester is too sensitive to get an accurate reading with the way they wrap the strands and you continually get false readings, and swaps are only good if you only have 1 bad light. If youre curious how it works, this tool injects very small probes in through the insulator and completes the circuit at a specific spot in the line, by-passing half of the strand. With process of elimination you will find your bad bulb/bulbs in no time.

You still have to check every light. Haven’t taken the time to figure out how

I was a skeptic but decided to try it. It works and is easy to use. I just rescued 11 strings of lights in a fraction of the time it would take to test bulb by bulb.

I did NOT want to spend money on this thing. But after several hours of googling and youtubing trying figure out how to diagnose and fix my half lit led christmas tree decor I came to the conclusion as every one of the articles and videos I watched...do it. The instructions werent great but I watched a video on how to use it before it arrived so I was ready to go. In less than 10 minutes I found three bad bulbs and had them replaced and had a fully functional light tree again. My only complaint is I didnt do it sooner. I shudder thinking about how many strings of led lights Ive tossed thinking they were unrepairable.

It does exactly what its supposed to. At the end of the season I had 3 strings of lights that only had half of the bulbs working. I was ready to label the strings and try to hide the dead spots next year. It took a little while to get the hang of it, but by the last strand it only took 15 minutes to find and fix the problem. I actually had 2 bad bulbs on that strand. I cant imagine how long it would have taken without this. Now all of my lights are ready to go for next year. The clamp tester and bulb tester both work great. I didnt get a chance to try the fuse tester and the bulb remover was not the right size for my external light string.

This product is a must have for every household that uses LED string lights! I fixed 2 strands of Christmas lights already and saved them from the trash! It has already paid for itself and its my first time using it. Love the tool to check if a bulb is burnt out.

So this tool helped me repair 3 long LED sets that were completely out. It would have cost me about $75 to replace the sets so I decided to try this tool instead. With it, I was able to find and replace many bad LEDs in the sets so that they worked again. It took me about an hour per set. In the end, I ended up replacing 15 bulbs total. Heres the BIG BUT if youre thinking of buying this. Do you have plenty of LEDs lying around to replace the bad ones? This does not include replacement bulbs. Remember that LEDs are NOT universal. Every set seems to use a different shaped base on its bulbs. I used an x-acto Knife to reshape the bases of the LEDs I had lying around to fit in different sets. On 2 of my other sets, I gave up because the bases were badly corroded. This kit includes 2 replacements for corroded bases so after that what are you going to do? Also, in my case, even though I got the sets working, what happens when they fail again? Im out of bulbs and once they are on the house, Im not taking them back down to troubleshoot in the winter. The bulbs are all the same age so it stands to reason that there will be plenty more failing soon. After this season, I will be buying new sets on clearance. So the decision is yours. How old are your sets? Do you have the patience to troubleshoot? Do you have lots of spare bulbs? Are you sure its just a bulb issue and not corroded sockets? The tool works. Start halfway up the set and work your way down the line. It lights up what works and easily tests individual bulbs once you remove them. It comes with a 9V battery installed and ready to go. If you have lots of bulbs out, test one at a time using the tool crimping the wire until you start finding bad ones (start at the end closest to the plug. Good luck!

I have had the Light Pro for incandescent Christmas lights for years and it works great. Its quick and easy. The LED keeper is much harder to use and when you find the problem their correction is not ideal. I watched all the videos and they made it look easy, but its not as easy as it looks. I was a general contractor for over 45 years and know my way around electricity. I bought this unit thinking it was going to be easy. It maybe for you, but it wasnt for me.

So this thing half worked, thats why I am giving it 2 stars. Cons- I will start with the cons. I had 10 sets of net lights that had sections that didnt work. I plugged in the unit and tried the gun part to find the section that didnt work. Well, it didnt work, anywhere, at all. I tried it on multiple parts that worked and didnt work, and I got nothing. I wasnt sure if I was doing it wrong, so I watched YouTube videos, yup I was doing it right. I also tried a strand of LEDs (not net lights) that were all working and nope, still didnt work. So that was a HUGE letdown. Pros- Even though the gun didnt work, I was happy the little tool at the end to remove the lights worked great. The light tester part also worked great too. Tips- Of the 10 light sets that had sections missing, I marked those areas and removed all the non working lights one by one, and I found the bad lights and was able to replace them. When using net lights, all 10 sets had the bad bulb on the unlit strand on the left or the right. For example, if you have 4 sections missing, the bad light was either in the row on the left or on the right. While taking out each light and testing it was NOT what I had in mind, this tool somewhat helped check the bad bulbs. Would I spend $25 again for this, absolutely not. However if you have a bunch of time to waste like I did, this did eventually get the job done. Good luck!!!
