Item Information

The Z-Bulb Plus Electric Fence Light is designed to let you know that your electric fence is working without any worries. The Electric Fence Light only draws current off the fence until something else touches it. When that occurs, the light will disengage and send the full shock to the animal or person that is touching the fence. We recommend using a split bolt to attach the Electric Fence Light wires to your fence or it will arc and burn your fence. The Z-Bulb Plus Electric Fence Light is designed for fence chargers that are (0.15 Joule) or 10 mile chargers and larger. The larger the charger the brighter the light becomes!!!

  • The brightest Electric Fence Light on the market.
  • Only uses current off the fence until something touches the fence.
  • Z-Bulb Plus has a very long bulb life.
  • Bulb has a two year warranty. (Does not include Lightning damage).
  • Flashes with every pulse of the fence charger.
  • Included Knocker makes an audible sound in case you cannot see the light.
  • Can be seen up to a mile or more away!!!
  • You don't have to always go outside to check your electric fence anymore, just look out the window!!!

Rated 5 out of 5 by from Great customer service I have 2 ELF lights on about 6 miles of cross fences. I can check my fence from dusk to dawn by just stepping outside without have to ride fence testing. Today had one quit working contacted customer they said they would ship me new one out today ,but wanted me to try trouble shooting we got it figured out and back on fence flashing. Great product and customer support, highly recommend them.

Rated 5 out of 5 by from Great product. Needs to be in stores that sell electric fence chargers. It saves you time on checking working status of the fence. Great product I bought a few weeks ago. Definitely will purchase again.

Rated 2 out of 5 by from Adequate enough for what it’s intended for. From dusk to dawn I can see it somewhat clearly about three acres away, which is adequate enough to keep me from going out at night to see if the pasture fence zapper is on. Daytime, unless I’m almost looking right in the lens, it’s difficult at best to see the flashing light. I’ll probably replace it if I find something better. Until then it’s adequate enough for my current purposes.

Rated 5 out of 5 by from Super bright w/louder knocker Light flashes brightly w/elect pulse and knocker is a good bit louder than the standard bump that’s heard at the pulse of the charger. Works very well for my purposes.

we have some battery powered fencers. will it drain the battery by flashing all the time. The fencer we want to put it on has three separate lines coming from one fencer. The fencer we are wanting to put it on normally puts out between 3000-4000 volts

Asked by: nswan
The Electric Fence Light (Z-Bulb Plus) will draw current off the fence which also means that the battery will not last as long unless you have a Solar panel recharging the battery during the day. 3000 to 4000 volts is not much and this also tells me that there is grass or weeds drawing current from the fence charger or the charger is not very big. You must have a least 3,000 volts to even make the light flash. A 12 Volt DC fence charger should be able to put at least 7,000 volts out and if not they may be going bad.

Can you turn the clicker part of it off?

Asked by: Glrdgrs
Yes, you can turn the knocking sound off by turning the outer body of the knocker and sliding it down out of the way. You will be able to see the spark gap and it will spark with very little sound. You can leave it this way and it will still work just fine.
