Can the LightKeeper Pro fix LEDs?
Due to the different physics behind incandescent and LED light sets, the LightKeeper Pro cannot assist with LED light sets. But thankfully, the company behind the LightKeeper Pro also offers the LED Keeper -- the complete kit to repair LED light sets!
How to tell if you are working with incandescents or LEDs?
a) Incandescent bulbs have filaments and tend to get warm when lit a while LEDs do not
b) Remove a bulb and look to see if the wires are offset or not [Offset = LED; Equal height = Incandescent]
c) LEDs have a plastic encasement while incandescent has glass
-
What type of bulbs come with the LightKeeper Pro?
Non-flashing, Clear 2.5 volt Replacement bulbs, 170mA and 0.425 Watts.
Can this tool fix a strand where every other light is out?
The LightKeeper Pro can assist with incandescent light sets that are wired in series, meaning you can remove one bulb from a functional section and the section will become unlit. Typically, if every other bulb is out then we are dealing with a control box or a light set that is not wired in series. The LightKeeper Pro cannot assist with light sets that have control boxes, rope lights, battery operated sets, or LEDs.
-
Why buy this for just a string of lights?
The LightKeeper Pro is great for pre-lit trees, icicle lights, net lights, wreaths, wire frames with lights, and other pre-lit décor!
Does this tool work with 220 Volts?
No, the LightKeeper Pro was designed for 120 Volts only. Thankfully, there is an International LightKeeper available which is designed to work with 220 Volts (outside the U.S.).
Product Description
Save your pre-lit trees, wreaths, light sets, garland, & more!
The LightKeeper Pro fixes incandescent holiday lights with the squeeze of a trigger in seconds. It is every decorator's must-have and saves you not only time, but money. No need to toss your pre-lit decor when you have lights out. Use the LightKeeper Pro to keep your holidays bright!
Great for Pre-Lit Trees & other pre-lit décor

Complete Tool for the Repair of Incandescent Light Sets
The LightKeeper Pro pays for itself and is provides everything you'd need to fix a light set:
- Built-in Bulb & Fuse Tester
- Includes 10 Spare Bulbs
- Contains a Storage Compartment for spare bulbs & fuses in the handle
- Comes complete with batteries
- Has a Bulb Puller
Two Repair Methods in One Tool
The LightKeeper Pro contains two repair methods:
- The Quick Fix Repair Method - Simply plug your LightKeeper Pro into an empty socket on the faulty light set and pull the trigger. The LightKeeper Pro sends a pulse through the light set, finds the bad bulb, and fixes the shunt—allowing the light set to work properly. A Shunt issue is the #1 cause of light set failure.
- Audible Voltage Detector - When your light set is not experiencing a Shunt issue, you can use the Audible Voltage Detector to find other interruptions such as broken or missing bulbs, socket issues, etc.
Every decorator's must-have!
This Cool Yule Tool saves you time and money. No more throwing your light sets and pre-lit décor away. Now you can save them with the squeeze of a trigger.

There was a problem filtering reviews right now. Please try again later.
The single strands were the easiest. I started with a completely dead set first. With a swipe of the voltage detector, and one single click, the strand came to life and the blown bulbs were visible.
The icicle and chasing lights required both the click fix, as well as, good old fashioned light by light testing. The built in bulb extractor and tester made shoot work of what is usually a very tedious task. The bulb extractor did take a little practice, but the bulb tester is super simple. Since these are multiple circuit strands the voltage detector couldn't be used becuase at least one of the wires running the length always has voltage present. However this was not a big deal.
The idea behind the click and fix is pretty clever. Basically if a light blows a shunt at the bottom of the bulb is supposed to bypass the blown filament and keep the other lights glowing. However if the filament and the shunt are both broken the stand cannot conduct electricity and the strand goes dark. With the tool plugged into one of the sockets and the strand plugged into the wall you pull the trigger on the tool. It sends a short high voltage burst through the bulbs basically arc welding the broken shunt back into place. This will allow the strand of lights to light revealing the blown bulb or bulbs. The high voltage emitter is a similar to what is used to start a cheap propane grill, or a butane lighter. It's pretty much the same clicking noise as well.
One thing I did notice was that if the shunt is too badly damaged the high voltage is not enough to weld it back together. However you can still see were the break is because when you squeeze the trigger the offending bulb will have a little high voltage arc visible inside.
I have to say my favorite feature was the bulb tester. You can make sure a bulb lights without the pain of putting it in and out of the compression sockets on the light strings. This was really helpful as I was using bulbs from a donor strand that had a broken cord. The last thing I wanted was to replace a bad bulb with another bad bulb.
All in all I was able to repair over $100 worth of lights with a $15 tool in a couple of hours time. I highly recommend this product for the number of tools built into the single unit, it's ease of use, and excellent results.
Initially I set up tree to check out condition. A section would not light. Sent out family text to ask for help. My son responded and told me to purchase this product. Received it and set it up and initially found three burnt bulbs out of the bunch that were burnt out. Replaced all three and yes, lights were back on. Yet over the course of a few hours, replaced several! It’s as if they all starting burning out and replaced as I found new spent bulb. Then, after many replaced, it leveled out and all lights were stable.
So happy and satisfied with this purchase. It saved me the cost of a new tree. Which I didn’t need nor did I want. Also purchased extra bulbs. Glad I did. While they come with the tool, I needed many more than that. So don’t be surprised if after initial bulbs replaced, more start to go.
Grateful is the word. I like my tree and very happy I can set it up again this year!

Other things to note:
- The packaging has a lot of details about different ways the product can be used to diagnose issues and repair light strings. I only used one of the ways for the issue I was working with.
- the company that makes the product seems to have good costumer service. They seem invested in their product and have notes on the package with ways to get more help if the instructions aren’t sufficient for you, including videos tutorials and a phone number where they can help you learn to use the product. I thought that was cool. I needed to use the video to understand the best method for finding the dead bulb amongst the tree branches, and I found it really helpful!
