FLASHING INSULATOR SHOWS ELECTRIC FENCE IS WORKING
You don’t need to go outside to see if your electric fence is working with this new flashing insulator that attaches to any fence post. The Insulight works off the surges produced by your electric fencer. It consists of a blue HDP plastic insulator and an enclosure that contains a flashing red LED light that flashes with the pulse of the fencer. The flashing light can be seen from up to 1/2 mile away.
