Electric Fence Light Alarms & Indicator Lamps

An invaluable 'alarm' for showing when there has been a drop in the voltage through the fence. This small, lightweight unit simply clips into the fence line and the red light will flash if the voltage drops below the correct level (2 settings). It also serves to remind you, from a distance, whether the fence is on or not.


It has an off switch, and a high and low switch depending on the type of fence it is monitoring. We recommend using the low setting for any electric netting and polywire, and the high setting for others such as tape or galvanised wire.

FSF Tip: Hang it near to where the power goes into the fence. Works best on tape or rope

Hangs on the fence and flashes with the rhythm of the electric pulses (approx. once every 5 seconds). Can be seen in the dark from a considerable distance to show the fence is working.

The constant flash does help to deter and un-nerve predators so acts as a deterrent. Particularly useful when hung on poultry netting.

If the fence voltage drops below 2000v the light will stop flashing.

FSF Tip: Hang it near to where the power goes into the fence.

The Flash 2000 Fence Control Device shows the user that the fence is working.

Flash 2000 flashes a green light with each impulse and stops flashing when fence voltage drops below 2000 volts (as opposed to the Volt Alarm which starts flashing when the voltage drops below 2000).

Very useful as an optical function control during darkness to indicate whether the fence is on or not.

Just clip to the fence and it starts working, it does not need to be earthed.

FSF Tip: Great on tape or rope but not the best option for poultry netting, the Neon Indicator Light above is the better choice for netting.
