Product Description

A Cool Yule Tool. Fix holiday lights with a squeeze of a trigger. The Light Keeper PRO is the complete tool for fixing miniature light sets! A must for Christmas time. This all-in-one tool fixes most light sets in seconds by addressing the damaged bulb at the plug or at the socket. The LED Head Light helps visibility in light repair. The Audible Continuity Detector traces the circuit to the point of interruption. The 3-way bulb puller helps release tight bulbs from their sockets. The Bulb & Fuse Tester tests both indoor and outdoor mini lights. There is a spare bulb compartment in the handle for storage of extra bulbs and fuses. Three (3) 1.5-Volt Batteries are included. Patent pending. The trigger send a pulse that will activate a defective shunt; This fixes the circuit allowing the current to flow. Simply plug your Light Keeper PRO into the light set, pull the trigger and a pulse goes to the bulb, fixes the shunt and allows the light set to work correctly. The light keeper pro is not intended with led, rope or light set/sets with control boxes.

5.0 out of 5 stars How it works December 14, 2008
Okay, admit it: you read the package, mix in even a basic understanding of electricity, and wonder why anyone would fall for such an outlandish claim. Surely, you can't fix a lightbulb by passing more electricity through it, no matter the "shape" of the pulse!

This DOES work, though, and it's because Christmas light bulbs have long been designed to work this way. Every bulb in the light set you own has a "shunt" which is supposed to "melt through" when the filament burns out. And, fairly often, it works just fine. However, every once in a while the shunt doesn't melt through given the "normal" voltage difference across the bulb, and so the circuit (for the 50 lights in that set or portion of the set) is lost. That's when not just one lgith goes out (which you might often not even notice), but the entire section of lights turns off.

That's where the "pulse" fixes things. It provides a low-current, high-voltage difference across the bulbs, which is sufficient to melt the shunts in any burnt-out bulb while not affecting functioning bulbs. Then, you scan for the bulb (or two) which is/are still burnt out, and replace just those. Those are the ones which have been burnt out from the start, but at least one of whose shunts had not melted through.

Now, that said, where can this process, and thus product, fail? For one, if there are a huge number of burnt-out bulbs in your chain and they ALL failed to melt through their filaments, it is likely that the device won't be able to work through them.

Further, if you have a *loose* bulb in the set, this will do nothing at all for you. You'll need to use the current detector (also a part of this device) to scan along the wire to see where continuity is lost, and replace that bulb or try just reseating it.

5.0 out of 5 stars Works great December 29, 2006
Amazon Verified Purchase
This item is more expensive than others in its category, but it works great! I was able to fix multiple strings of lights in a matter of minutes instead of getting frustrated and throwing them out like I used to. I liked it so much I bought one for 2 of my family members as well. Just take one of the lights out of the dead string, and plug the empty socket into a receptacle on the front of the device. Pull the trigger about 10-15 times and all of the working lights light up making it easy to identify and replace the dead ones. After trying 2 other similar devices that did not work at all, this was a great find and I highly recommend it.

5.0 out of 5 stars LightKeeper Stress Reliever! November 23, 2007
Being a skeptic it was sheer frustration and some positive web reviews that drove me to get this. I had two strings out on a pre-lit tree and was contemplating my limited options. After buying this I had both strings repaired - two bulbs per string - in 15 minutes. THIS PRODUCT WORKS AS ADVERTISED! I plugged it in and had to give only one pulse on each string and all working bulbs lit up! I no longer stress about a string dying during the season after the ornaments are on. I highly recommend it!

3.0 out of 5 stars Doesn't Seem to Help in the Long Run August 17, 2008
Amazon Verified Purchase
Well, this gadget does work, although not quite as crisply as I had hoped. When you insert individual bulbs in the tester portion of the LightKeeper, these bulbs tend to wobble. You don't know for sure if you have them settled in satisfactorily.

But the bigger problem with this gadget is that it is really not able to salvage many chains of lights. So far, it hasn't salvaged even one of my decorative chains. That's because when you get to the point that your light chain is not lighting at all, and you want to test to see which lights might be the dead culprits - it's likely ALL or almost ALL the lights in the chain are dead and you are better off discarding the chain. That has been the case with me. The LightKeeper has shown virtually all the lights in all my problematic chains to be dead, and I've ended up just going out and buying new chains.

That's always likely to be the case, because when one light in a chain blows out and you don't promptly replace it, the other lights have a higher, taxing voltage distributed across them. They too then quickly become vulnerable to burn-out.

As for the LightKeeper's other function - its ability to deliver a jolt of voltage across the gap in a burnt-out light and thereby to melt the connections back into series - that too seems to be a better idea in principle than in practice. In the cases where I've had just a light or two out in a chain and have delivered the LightKeeper's jolt to the offending light in order to solder it back in line - the light has lit for a few seconds. Then the entire chain has gone out. This is probably again because the presence of even that one dead light in the chain over time weakened all the other lights with the increased voltage being delivered to them.

5.0 out of 5 stars It WORKS! November 21, 2009
By SKF
I found this product in Target. I have several strands of star and snowflake lights that were half out. I was frustrated they would have to be thrown away and I bought this as a last ditch effort thinking I had just wasted $20, but IT WORKS. In a few minutes i had all my lights working again. This would be perfect for Pre-lit trees. Great product.

5.0 out of 5 stars I Was Amazed March 29, 2007
This product really works, right out of the box! I first tried it on a small Christmas tree that I had worked on for a half hour. Three pulls of the trigger and it lit right up. Next, I fixed two older light strings with one pull each. The instructions are very clear. The clear plastic case is re-closable. It's a great value.

We tried this over and over, but it only worked to light up half of one string that was out. Then it never worked on any of the others.

Anyone with Christmas trees needs this product. It is an absolute necessity for those with pre-lit trees. To quote the vernacular/homily, this item is better than canned beer.
