These guys get laid.

UGH!!! NOPE! Doesn't work!!

So I attached the socket of one of the lights that were out. I clicked the trigger as indicated. Now all of the clear bulbs that were out are blackened instead of clear!!?!!! Not helpful at all!

Boa tarde!! alguém sabe me informar onde comprar um desses ?

Awesome and informative! Thank you!

This works, BUT Putting the tree to bed today, I went through the five sections of the tree to fix secti9ons that were bad. These lights are wired to the tree: 1. It wont find a loose bulb. That was my problem on two sections that I found by accident. intermittent

Our lights do not go out. They ‘blink’ and just turn white. It is a handful of them. When we turn the power off those lights stay lit and colorful. It’s here and there. Sometimes it can go for a week without an issue. Anybody with any ideas?

Great tutorial but could do without that horrible organ background music! Thanks!

The problem is that 10 years later, after this video was made, they've changed the net lights. Now, there are hooks at the top of the bulb to string them together. There is no way to insert the bulb housing into the trigger pull. It doesn't fit.

For a 10-year-old video this has remarkably clear video and audio. I appreciated the lucid and "enlightening" (haha) explanation. Two thumbs up!

Came home to a light strand out in the center of our tree. LightKepper Pro made for a quick repair identifying a faulty socket. Thank you very much! Merry Christmas

A nce adjustment of my problem. I developed much of the plans but 1) 20 pulses.. I was told 3, I used 5 or 6!! 2) I have a wired angel about 5' x 7' who has the metal conduction of the signal. The mini bulbs are next to each other. Over 30 years, I have had to pull the bulbs and test them as I thought the signal was carried by the steel frame. It has been a challenge as all worked until I hauled the angel to the location. The left lobe of the "skirt" is dead. Concerning the conduction of the signal on the steel wire, it has been a bear. I appreciate your lessons. I found the "Lightkeeper" back then, then about 10 years later I came across the Pro.

now this is trollery

I’m disappointed it doesn’t work on LED lights

So saw this. Bought it. Middle of light string is out. The click thing didn’t do anything at all, tested every single bulb and all tested fine but still doesn’t work.

I wish I'd watched this a few years ago when our expensive prelit garland failed, or my very expensive tree with light failure back around the time this video was first posted! Dealing with light issues on my current tree - just ordered the right bulbs and a LightKeeper Pro - and now watching this video so I can (hopefully) save my current prelit tree's lights for this Christmas season! Thanks for this detailed video, and wish me luck!

THANK YOU!!! I’ve used the Lightkeeper Pro for years with great success. However, this year I had one section of my tree that I could not get to light. After watching this video I was able to determine the problem and I would never have without the help. Thank you so much.

My bulb tester doesn’t work. How can I fix this? The fuse tester works, its just the bulb part that doesn’t light any bulbs. Please advise. Thanks!

She's not my friend. And consequently, she didn't tell me to buy one. But, I did anyway.

Amazing tool! A life saver! Thank you so much for inventing this amazing handy tool 🤩

Before you send your money on this Check to see if you can find replacement LED lights. I found burnt bulbs . But can't find replacements. You can not just use any LED. Each string is bulb specific.

I've rewatched this video every year for the past 4 years. A keeper!

I bought mine at a garage sale for a couple bucks. Nothing works as advertised anymore and I expected the same here, but I had enough hope to waste $2 on it. I've been working on this outdoor reindeer with a tangled mess of circuits and half the reindeer wouldn't light no matter what I did. Well Son of a Bitch, as sleepy Joe exclaimed after his criminal extortion of Ukraine... It worked. It took me all of 2 minutes to get the reindeer lit, and that's only because I was using it for the first time. Unbelievable. It actually worked. I think I'll put this under lock and key.

ken saved my christmas

THANK YOU FOR YOUR VIDEO I LEARNED PERFECTLY A GREAT VIDEO GOD BLESS YOU I FIXED 5 series of light bulbs in a short time

This saved the holidays.

I got this tool and tried it but only the top of the tree lit up. How do I fix the bottom?

My voltage detector just goes off when I put it near anything, including me and my ladder. Then sometimes it doesn't go off by the wire, but when I double-check, it goes off again... so confusing.

This guy taught me me everything I know about exterior illumination!

I watched it when I was 4 and I’m 17 and I have fixed lights since I was a kid🥲. Rich Fredrick is still here?

She may be the most beautiful women in the world.

Still watch this great video with Lights Out on strig decorations.. has helped many times!

It took a couple of tries to insert the wire properly into the slot, but I got it working and it found the bad bulb. The light remover was also a little tricky. The key is to make sure the light remover metal slot is in between the gap on the light bulb. This video glosses over removing the light bulb.

Just purchased this followed instructions to the letter and it works fantastic after years of multimeter and voltage testers had 4 bad bulbs on 2 C6 sets and fixed them in a half hour. Great video great product, highly, highly recommend.

I bought one and I had 6 sets of lights on my tree fixed and going

This didn't work for me. $30 wasted.

I like how you obviously gloss over the bulb remover portion because it obviously doesn’t work

I have the light tester and the tester beeps at every bulb yet the strand remains as non working?

Thank you for this! I'm shocked at how much information there is.

The 35 minute point should be at start of video to save time

Holy cow. I’ve spent hours troubleshooting my prelit tree with three strands out. First pull got one strand on then several pulls and checking voltage got the others on. I then replaced about 30 bulbs. Saved me a $150 tree.

4:39 In a series circuit 120V travels through the circuit but each bulb on a 50 light strand use 2.5 V . Its the sum of the bulbs voltages totaling 120V. Where in a parallel string each bulb gets 120V because each socket is an independent circuit . In a series set with 100 bulbs its actually a parallel of 2 series circuits of 50 bulbs and so a 100 bulb string still uses 2.5 volts per bulb. Its crucial to promptly replace burned out bulbs even if the string remains lit. In the example of the 50 bulb string if one bulb burns out you now have more voltage going to each bulb and so 1 burning out is not a problem but as more burn out the rest are getting higher and higher voltage and will begin to blow other bulbs rapidly until the set fails because the fuses will blow if the other bulbs take on the additional current left by the failed bulbs

I had forgot to mention that my wife had thrown the three that didn't work into the garbage and I hate that being the type of person I am I like to try and fix things and that got me wondering if there was a tool, and that brought me to KZbin and eventually your video. I saved it so I can watch and share it.

I am sure glad I found this video. It was absolutely perfectly explained. I had watched to videos before this one and they were OK , they explained and showed how to use the tool, and that is exactly why I am here I was curious enough to want to know if there was a tool like this so I went on KZbin. We had 4 strands of lights, one worked the other three didn't and it got me wondering if there were fuses involved because the three strands that none of the bulbs lit up but I couldn't tell where a fuse would be until I watched your video and sure enough I check all the plugs and all three had two blown 3 amp fuses in them and that was we because we had had a power surge and outage the very night that all 4 strands had been lit up. So thank u for that informative video and if anybody else is reading this if none of the bulbs are lit on your strand check to see if there are fuses below the little slide out door it is pretty easy to do, thanks again, also I do have a voltage tester that detects power and it lights up and beeps but I am definitely going to get me your tool as soon as I can.

This is the video I really needed so thorough and informative thank you!!

Thanks again for existing @Lightkeeperpro! Mind blown 🤯 again and again ✊

Bogus. I'm judging by the age of the video that there have been improvements. But not on the one I bought. It never beeped to test a circuit. And turn the plug 180 degrees? Todays plugs and outlets only allow you to insert it one way. And how do you fix a strin with 4 on then 2 off then 5 on and 1 off. YOU DONT. Stay Away

I found the information on the shunt to be enlightening. I knew about the shunts and understood fundamentally how they work. I always assumed they were some sort of fancy wire. Nope. Just aluminum and utilizing the aluminum oxide layer as the insulation, clever. We had two fancy wall decorations that didn't work. I was going to throw them out. Used the instructions from the video, canniblized one of the two decorations, and got one to work and one for spare bulbs. One's better than none,, so we're good for a few more years. The LightKeeperPro is a good tool, it does have a learning curve this video helps with. However, I don't think it could have helped the light string the squirrels got to the other year.

The entire top section of my tree isn't working but when I use the voltage detector, I hear a continuous beeping in some sections and a slower beeping in others. There isn't any silent section. Do I replace all the slow beeping sections instead?

I just bought this tool (2022). I had been struggling for YEARS with mini Xmas lights. NO MORE! I actually gave a cheer when I pulled the trigger and my set came back to life. Truly a necessity.
