In the wood shop I mounted this nifty blue light up high on the loft over the air compressor. It lights whenever the compressor is powered, regardless of whether it’s running at the moment. This will make it easy to see if you need to turn the air on or off without having to walk all the way over to it.
For staff shutting down at the end of a day, you can quickly see if it’s been left on, even when the lights are off.
