Electric Fence Tester with LED Indicator Lights - 300V to 10kV Range | Detects Energizer Pulses | Clips to Wire or Tape Fences

UPDATE April 22, 2025: I just wanted to update this review. I'm still very satisfied with this indicator light. It has been through the 2025 Snowmageddon that we had here in South Alabama and it didn't miss a beat. Likewise, though the instructions tell you not to use the light during electrical storms...well, down here in the deep south you're gonna have electrical storms. Now, my fence is 12v DC so I'm not connected to the powerlines but still, there is the issue of this big antenna (the fence) picking up some induced current...so far, no problem!!! :) The indicator light is also very sensitive. I had an occasion where the ground probe was not in the ground and the light was still working! Next big test is coming up....can it stand the south Alabama heat and humidity of summer??? If it passes the summer test I'll say it deserves a ****** review!!!!!My fence charger doesn't have an indicator light on it, it's a 12v DC charger with a separate solar panel charging it. But, I wanted to be sure the fence around my vegetable garden was up and running without going out to the garden and checking the meter. I was hesitant about this light but decided to risk the ~$15 and see how it worked. My two concerns were that it might reduce the voltage on the fence. I had just done a lot of testing on the 7-year-old fence to realize the problem of low voltage (around 3kv) was at the main connection coming from the charger...replacement wire/added wire had simply been wrapped around the "bundle". I stripped all that away, made a complete new connection including threading some galvanized wire in with the polywire and "BOOM!!!" the voltage went to 9.5kv!!!! So, I didn't want the new indicator light to drag the voltage down. The other thing I was concerned about was the light's ability to withstand the elements (read: RAIN).Well, the best that I can tell using my digital fence meter is that it does NOT affect the fence voltage...still nice and HOT.The light's weather/water proofness I'm still unsure of though. We got hit with two pretty big rain systems shortly after I installed the light, both systems dumped 3+ inches each on us...one a fast rain, the other a slow rain. It has appeared not to affect the light any. There *is* a warning not to have the light installed during electrical storms....<duhhhh>....well, I'm not going out and taking it down every time I hear a clap of thunder here in south Alabama. My fence being a 12v DC powered fence it is not as prone to damage from lightning. Time will tell. One thing that I'm I'm thinking of doing is being a little proactive and sealing the seams/joints with some silicone sealant.As for using the light it is really simple....it's just like using a regular single-light fence tester. Just stick the ground probe in the ground and hang the light onto a strand of wire/polywire/tape/whatever and that green light goes to blinking!!! The light is pretty sensitive being as it was picking up a radioed signal from the fence before I attached it. I can see the light blinking easily from 250' away BUT you have to be pretty much head-on to it...if you're 45-degrees to one side of it your pretty much not going to see it. I like the limited angle viewing as it makes the light pretty discreet from "passer-byers" drawing little attention to itself. But, if you're in the angle of view for the light you can easily see it. I first installed the light on the near side of the garden fence but after a couple of nights with it there I chose to move it to the far side to reduce its intensity as seen from the house. Daytime viewing is naturally more limited but it can still be viewed at 100'.I've got until January 31st to return this light but I suspect that I will be keeping it. It works (for now) as described, it's been through a couple of heavy rains, and it is viewable from a good distance (within reason). So, for now, I'm just happy as a pig in a mud puddle. ;)

This is a handy little device. I have it clipped to the electric fence in my pasture and I can tell at a glance if the fence is on. The lights are bright green and easy to see.

I can see this from about 150 feet away in the dark or heavy clouds. I just wish it was brighter so I could see it in the daytime without having to be 30 feet from it in a direct line.

Works exactly as described.

It quit working a few days after the return window closed! It worked good for a little over a month though but really disappointed now.

Works as expected

I have an electric fence in my suburban backyard to keep the dogs separated from the chickens and rabbits and to keep the cat in the backyard and to keep predators out of the backyard. I was concerned that any indicator light would be annoyingly bright for my small space but this particular one is actually perfect. I can see it from my bedroom window, day or night, without feeling like I am in Vegas. For reference this mechanism is perhaps sixty feet from my bed. I like that it is green too. If it fails down the road I will adjust this rating.

Not bright enough for my use. I can't see the light from the house. Would work good for those that have a hot wire fence closer to the house for monitoring.
