GK13 Christmas Light Tester for Incandescent Strings, Bulbs & Fuses | Follow Audible/LED Alerts With Adjustable Sensitivity To Narrow Faults, Then Use The Retractable Puller On Removed Bulbs

At first we were going to send it back because it was glitchy. We were able to get it working properly. Great little tool!

This hs been a lifesaver! We have strings of lights along our bannisters and further. So every once in awhile, there’s a string of lights that half are working, and the other half isn’t. So I just bring in that string, and with this light checker, I can check each unlit bulb, and eventually I can find bill that doesn’t work, and replace it with many of my extra bulbs. I’ve been using this for years, and it’s still working perfectly!

This is a simple tester to allow you to determine if a lamp is failed. Given the frustrations of dealing with Christmas lights on the tree this makes the job of lighting the tree easier.

This product is not operating at all. Tried to replace batteries but that didn’t help. The tool does not function at all. Doesn’t detect ac outlets nor bulbs. Would not recommend.

I thought the idea was great! But I couldn't get the bulbs out with this tool. Therefore that being said, I cant even say how well this works. But I'm keeping it and will try again when I put up my tree in November.

Easy to use works well.

Works well. Useful on things other than Christmas lights too.

My Xmas tree after many years finally gave up on a few lights. There were too many lights for me to remove and replace so I got this Tester to locate the culprit and replace it with a new bulb. I sweated over the whole project, buzzing every light connection, etc. After having located what I thought was the broken one, I turned to the "bulb extractor" gadget on the unit. Forget-about-it. Does not work because it doesn't fit around the bulb. I had to resort to pliers in each case. Plus that piece was flimsy and poorly designed. I sent it back.

My Christmas lights wasn't working. Since I got this, it did a good job. All my lakes are working again.

It works very well to check bulbs and the tiny fuses.

Let’s be honest: Before this little gadget showed up, my electrical “strategy” was basically: poke the wire, squint, hope for the best. Not exactly the safest approach for someone who enjoys being alive. Then this tester arrived… and suddenly I felt like a certified electrician. Wave it near a wire? Beep! Outlet acting suspicious? Beep! Light switch that looks like it’s plotting something? Beep! It’s like having a tiny, judgmental safety buddy that warns you before you do something questionable. Why it instantly became my favourite tool: - Super sensitive, picks up live wires faster than I pick up snacks - Bright, loud alerts you can’t miss - Lightweight and easy to stash in a drawer, toolbox, or “junk but not junk” kitchen spot - Perfect for DIY'ers who want to avoid accidental fireworks - Makes you feel way more confident working around outlets, switches, and mystery wires The moment it won me over: I used it on a wire I swore was dead. Spoiler: it was VERY alive. This little tester saved me from becoming a human lightning rod. Final word: If you do ANY home repairs, even tiny ones, get this. It’s cheap, reliable, and honestly feels like a cheat code for not electrocuting yourself. My nerves, my walls, and my eyebrows are grateful.
