The LightKeeper Pro Light Tester fixes most miniature Incandescent lightsets 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.

Features a handy storage compartment built into the handle for housing your bulbs and fuses.

Answer: 
The Tester has two different ways to detect a bad string. The "quick fix trigger method" identifies and repairs a "shunt" (or an internal bulb failure"). It seems a little like magic...and it worked for me on the first string I fixed.
If the quick-fix doesn't work, the "audible voltage detector method" helps find the precise location where the voltage is interrupted (broken/loose bulb, etc). Unlike the Read More

If the quick-fix doesn't work, the "audible voltage detector method" helps find the precise location where the voltage is interrupted (broken/loose bulb, etc). Unlike the quick-fix, the tool doesn't "fix" this problem...you still have to replace the faulty bulb. I had to use this method several times, too...it's slower than the "quick-fix," but much quicker then inspecting each bulb individually. Read Less

Sometimes a bad bulb is not the problem. I had three half-lit light strings and I pulled a bulb on the non-working section, stuck the socket onto the device, pulled the trigger and the unlit portion lit right up. It is amazing. Then I replaced the random bulb that I pulled out.

Answer: 
It does not fix the bulb. It sends a signal that melts a shunt in the bulb that has burned out or stopped working, causing the current to flow through the defective bulb and completing the circuit.

Once the bad bulb is identified you remove the bulb and check it with the device. If the bulb itself is bad you then replace with anew bulb. The device comes with six replacement bulbs.

Pull out the bad bulb, put in new filament/bulb ( you get several in the package) or get one from an old sting that you keep for spare bulbs. You can see how to do this online with utubes, very easy. Read Less

Answer: 
I don't think it does fix the blown bulb. It just shows you where it is. There's a tool attached to the device to help you take the bad bulb out so you can then install a new one. That's the way I think the thing works.

I am an electrician.
I have spent many hours with this thing trying to fix my pre-lite tree with no-results.
It is a tic traser which can give you false signals as easy as good ones.
You can test each bulb with it.
It you remove each bulb and put it in the test slot for bulbs.

Yes it can work on outside lights (the mini lights). As for prelim trees most of those are led light and this one does not do LEDs. The company makes a differant one to work on LEDs. Their web site address is in the material accompanying this device.

The tool is particularly handy at troubleshooting non-LED light stands that are already hung (outside, on pre-lit trees, wherever) to identify the bad bulb. However, that feature of this tool will not work on LED strands.

As another reviewer said, this gadget saved me from trashing my $500 pre-lit Christmas tree. It took a bit of effort to get the hang of it, but with patience and some knowledge from my past life as an electrophysiology nurse, I figured out the connections and the procedure. I was able to fix whole sections of tree light outage and ended up replacing only a few bulbs. I did the fix several days ago and every light is still lit. Many thanks to the inventor. Buy it!

I have a string of 6-6' Halloween skull fencing light-panels plugged together and on a timer... I had one panel quit a couple of nights ago... Bummer! Had a friend tell me about a gun thingy that would help me find the problem... So off to home depot brought it home, did a quick read through of the instructions and watch video online! All I did was turn on the power, as per instruction pulled a bulb from the dead panel, inserted the socket into the gun, pulled the trigger ONCE and my lights are back in business! This device is worth every penny! Going to purchase the LED version for my christmas lights too!

I was amazed when I put the gadget into the first light set I was trying to fix, clicked it once, and on went the lights! I really was not expecting this to work at all. What a time saver! Unfortunately, this was not the case with all the sets. It was especially difficult to fix blanket lights, but it did fix one of the blanket sets. If the quick fix option does not work, the voltage finder option did not work for me. But I've only had the light tester a few days; with practice, I might be more successful with it. I'm anxious to try this gadget on the garland lights and the prelit trees. I'm going to be buying this for those on my gift list that fix their lights.

UNBELIEVABLE....I am writing this right now after using it the first time. I bought this last year on sale, end of Season, after I had spent hours and hours pulling/checking one bulb at a time on 4 Reindeer to get them to lite up. I said next year if I have problems I'll try this thing. Well, today, one had half the body and 3 legs out so I plugged it into the gun and pulled the trigger 30 times and then plugged the deer back in, KAZAM the whole deer lit up with 2 bulbs out that I just now replaced. Unbelievable, this thing just saved me sooooooo much time.

Rated 1 out of 5 by from It didn't work for me The quick fix method did not work despite trying it multiple times. I tried the voltage tester & think I found the interruption but after replacing several bulbs in the vicinity it still didn't light the string. Also I had to remove the string from the pre lit tree - the beeping is not consistent unless you hold the device exactly right. You need a lot of patience and a lot of time to use this device. In the end I bought another string of lights. When I have a few hours to kill I'll try again.

I had already replaced the fuses, and changed several of the bulbs on a line that didn't work. As per instructions, I removed one bulb, and it fixed the entire line. I replaced the removed bulb and everything works. It says to pull the trigger up to 30 times, but I didn't even have to pull it once to get everything to work. A real time saver.

Having purchased a light tester many years ago with poor results, I was extremely skeptical of this product. Twenty dollars seemed a little steep, but given the prospect of purchasing a new artificial tree, I bit. Imagine my amazement when I plugged the first light socket from a faulty strand into this gun, pulled the trigger, and . . . it worked. Pure magic, in my book.

Rated 4 out of 5 by from Exceeded expectations I fully intend this to be returned if it did not perform. However it was pleasantly surprised and it made repairing my lights easy if time-consuming. The time-consuming part was just the nature of checking hundred light strands The voltage meter could be a little more clear in its signal but other than that if you sister and the light bulb tester are awesome.
