Series a light bulb in the circuit, Grandpa did it at the hog pen to keep the bores away from the sows and piglets all the time. Never lost a hog to the fence and it did keep us youngâ€™ens out and off the boreâ€™s backs. Noting is more fun for a 6 to 10 year old than to ride the hogs.
I donâ€™t recommend this type of fence instead use an electric charger. The cost of a small unit is about $30 and a good one could cost upwards of $400. I use a Gallagher 880 that produces 25 Joules at about 2000 volts for one tenth of a second once every second. This will not only keep the livestock in the fence but it also deters unwanted guest.
It is also legal.

The fencing unit is what is legal not the light bulb.
