INSULIGHTS

INSULIGHTS, Invented By A Horseman Who Needed To Find a Better Way

Bill Brown isjust a farm kid trying to keep the cattle in. He grew up on 700 acres and 150 head of cattle in Northwest Iowa, and his wife Sue grew up on a dairy farm nearby. Like countless other farm kids, they walked the fence lines to check if their electric fence was live. When the animals got out, it was like a fire drill — all hands on deck. The task of checking their electric fences followed them into adulthood. After the initial shock of one of their horses getting out and being hit by a car, Bill thought: There’s got to be a better way. After much dedicated research and the quest for just the right design, INSULIGHTS were developed in 2018. Tested in the harsh Iowa weather, which can fall to -15 degrees in the winter and reach 120 degrees in the summers, Bill and Sue stand behind the Insulights electric fence monitor with a 1 year warranty and satisfaction guarantee.

INSULIGHTS Are Visible From a Long Distance!

Who wants to go outside in the dark, or the rain or snow and check the fence?Wouldn’t it be easier to just look to see if the fence was hot? In 2018, Bill and his wife Sue foundedINsulightsa company dedicated to keeping livestock and crops safe through their patented electric fence monitor. By simply looking down the fence line, the flashing indicator shows that the fence is live. No walking the lines. No checking with pliers. It’s also designed as a wildlife deterrent, with blue plastic, a color known to deter deer, and red flashing light, which mimics a predator’s eyes at night. Insulights are visible up to 1/2 mile away at dusk or dawn.

Can INSULIGHTS Be Seen During The Day?

Yes! INSULIGHTS are visible during daylight hours,like LED Christmas lightsthat can be seen from several yards away on your Christmas tree— only these are brighter! At night, the high-intensity LED is extremely bright and can be seen up to a half mile away. Insulights are not intended to be installed on every fence post; most customers place them approximately every quarter mile or at locations visible from the house, shop, or vehicle.

Do INSULIGHTS Help To Make My Electric Fence More Visible?

Absolutely! At night, Insulights clearly indicate both the presence of the fence and that it is energized. This is especially appreciated by trail riders and campers, as Insulights function as a warning light around trailers and campsites while confirming the fence is working. They also help make that fence more visible to your horses!

Why Is Having “No Grounding Wire” Important?

Electric fences operate by sending a pulse of electricity down the fence wire and require a return path for the current. Proper grounding provides that return path and allows the energizer to function correctly. Insulights must also be grounded in order to indicate that the fence is working. When the fence is properly energized, the Insulight flashes. If a tree, branch, or other object grounds out the fence, the Insulight will stop flashing—immediately alerting you that the fence is no longer operational. Unlike traditional fence testers that require a wire and a ground stake placed in the soil,Insulights use a self-contained design powered by a 2032 watch battery.This eliminates concerns related to lightning, poor soil conditions, or installing and measuring a ground stake. Insulights are fully self-contained and simple to use.

Is It True That The Only Thing You’ll Need To Replace-Is The Battery?
Yes. The only maintenance required is replacing the 2032 watch battery, which, according to the manufacturer,should last 18 months to 24 months-much like changing batteries in a garage door opener. We make sure all batteries are included — so you won’t need to worry about it for about 18 months!

Do The Batteries Really Last 18 Months?

The 2032 battery itself is rated to retain power for over eight years when unused. In active fence applications, the battery should last for 18 – 24 months, according to the manufacturer. If a customer reports that an Insulight is not flashing, we suggest tapping it in their hand. If it flashes, the Insulight is functioning correctly, and the fence is likely down. Many customers report battery life beyond 18 months, but replacement intervals are similar to other household battery-powered devices.

What exactly is an INSULIGHTS fence monitor?

INSULIGHTS is a patented electric fence monitor built into the body of a standard fence insulator. Embedded inside the blue plastic housing is a small circuit board and an LED that flashes in sync with the pulse of your charger, so a steady wink of red light means the line is hot and doing its job. Each unit measures 3" wide, 3" deep, and 2 1/4" tall, weighs just 1.6 oz, and is visible up to 1/2 mile away at night. It mounts on the post or hangs right on the wire and works with high-tensile, braid, and tape, on steel T-posts or wood.

Who invented INSULIGHTS and why?

INSULIGHTS was founded in 2018 by Bill Brown and his wife Sue. Bill grew up on 700 acres running 150 head of cattle in Northwest Iowa, and Sue grew up on a nearby dairy farm. The idea was born of hard experience: after one of their horses got loose through a dead fence and was struck by a car, Bill went looking for a better way to know a fence was working without walking the lines or pinching the wire with pliers. When he could not find one, he built it himself.

How the flashing insulator confirms a live fence

The LED draws its timing from the charger's own pulse, so the flash is a direct, real-time read on whether voltage is reaching that point in the line. Ranchers commonly place a monitor every 1/4 mile so a single glance down the fence tells them which span has gone dead. You can confirm the whole system is hot from the kitchen window, the driveway, or the road, instead of testing post by post. The plastic insulators are molded by Den Hartog Industries in Hospers, Iowa, with the circuit boards made in Minnesota, and the Brown family assembles and ships every unit.

Built for Iowa weather and powered by a common watch battery

INSULIGHTS are Made in the USA and tested in harsh Iowa conditions from -15 degrees F to 120 degrees F, so they hold up through hard winters and brutal summers. Power comes from a single #2032 watch battery, the same cell sold at any drugstore, and it lasts 18 to 24 months before a simple swap. Every monitor is weather resistant and carries a 1 year warranty with a satisfaction guarantee for replacement or refund within 12 months with proof of purchase.

Keeps livestock in and deters deer at the same time

Beyond monitoring, the unit pulls double duty as a wildlife deterrent. The blue plastic targets a wavelength deer perceive strongly, while the red flash at night reads to wild animals like predator eyes, helping push deer off your fence line and out of orchards and crops. INSULIGHTS are used on ranches, farms, and orchards across the United States, Canada, Europe, Australia, and South Africa, and the design earned a spot among the Farm Bureau Top 10 Ag Innovations of the Year.

How to buy INSULIGHTS and what is coming next

A single Insulights Electric Fence Monitor is $24.99 at insulights.com, and the Buy 4, Get the 5th Free bundle of five monitors runs $99.96 (regularly $124.95). You can reach the company, by, or by mail at 1024 NW 33rd St., Ankeny, IA 50023. Bill is also developing a Smart Monitor that will text users the voltage and viability of their electric fence, which he calls a way for ranchers to "know the fence is down before the cattle do."
