## Overview

The EFL Electric Fence Light LED Bulb is a precision-engineered indicator bulb designed exclusively for electric fence chargers rated at 2 Joules or less. It flashes in sync with each fence pulse and emits a distinctive knocking sound to confirm proper operation. Its 360-degree LED visibility extends up to one mile, providing a reliable, real-time status check of your fence’s integrity from ground level or air. Enhanced with a sensitive spark gap, it instantly detects fence interference, making it an essential tool for professional-grade electric fence monitoring.

## Description

Our LED Electric Fence Light is designed for fence chargers that are 2-Joule or less . The Electric Fence Light let's you know that your electric fence is working good. As long as the light is flashing with every pulse of the fence charger it means all is OK. If the light is not flashing, it means that something else is drawing on the fence. Adjust the Spark Gap as wide as you can with it still being able to spark. This sensitizes the Spark Gap with your whole fence and if anything touches the fence it will get the full shock and the light will not flash at that moment. Remember the Spark Gap only draws current until something else touches the fence and it will not spark until whatever touched the fence is gone. Attn: The Z-Bulb Plus model is designed to replace the LED model and the bulb does not blow check this new design out with a guarantee.

## Features

- Emits A "Knocking" Sound When Fence Charger is Working Properly
- Can be seen up to 1 mile away, 360 degrees and from the air

## Customer Reviews

### ⭐⭐⭐⭐⭐ working good
*by A***R on January 2, 2024*

after 60 days of using this it is working good.i am running a parmak 5 fencer so my fence is hot (i have a critter problem).this light will flash every two pulses of the fencer witch is good for me.it was a bit fussy to get the air-gap set right for the popper, to close and it pulls to much power out of the fence to much and it will not jump. for me it seams to be 3/8 of a inch gap.i am going to try to contact the seller and see if i can get a spare bulb to keep around.i would say yes this works good but you are going to need a real fencer not a tractor supply junk one. they just don't have the power behind them.

### ⭐⭐⭐⭐⭐ Great product and company!!!
*by A***R on February 13, 2020*

When we got this light we could not get it to work. There was a number to call in with the paperwork if there was a problem. I called and left a message thinking that I would not get a call back. John call back on Sunday!!! We continued to have problems and had numerous calls to John. He was very knowledgeable and gave us many ideas on what to do. In the end, the light works perfect as the problem was human error in the grounding of our electric fence. If it had not been for John's patience, knowledge, and his desire to get the light to work, we would have sent the light back thinking it was a bad product. I would recommend this company to anyone thanks to John.

### ⭐ Does not work
