Does it exist? 120v inductive indicator light system.
I run a car wash and I need a way to quickly tell if equipment located in hard to get to places is on and working or not. What would be great would be a remote bank of lights that came on when a device was drawing current. What would be perfect is if I didn't have to wire it into everything - for instance inductive sensors (like the cheap ones you can buy at HD that beep and flash when current or voltage is present) that can be placed on the outside of a wire run and report back to the bank of lights whether or not there is current flowing.
Anybody ever seen anything like this?
