Signal light - PowerBlinker
- flashes with every fence impulse
- under 3000 V light stops flashing and thereby shows that the fence is no longer safe
- using it on several spots on your fence gives you easy visual control of your fence status 'in situ' even during the day
- also ideal as additional defence against wild animals!
