Light for air compressor.

Or just leave it on?

My compressor never got shut off in the 12 years I had it setup (recently moved)

After you have a compressor stay on and run continuously for a day or two you might rethink not shutting it off.
I forget what caused mine to stay on but it ran long enough that the compressor was smoking it was so hot.
After that I shut off, if I remembered. A while later I tied it into the shop lights.

Years ago at a shop I worked for someone forgot to shut off the compressor on a Friday. Sometime over the weekend a hose blew and the compressor was running when we opened Monday.

Depends how often you're out there, how often you use it, and how badly it seeps down on its own.

I'm not out using it enough to waste the electricity. It would be seeping and restarting a lot for nothing.

I managed to do something COMPLETELY different.

I have my compressor energized virtually all the time. If I leave for a few days, I might turn it off, but otherwise, it's active. I have a quarter-turn shut-off valve between the tank and a regulator that then feeds the copper lines that run along the ceiling. One side of the regulator block has a gauge, the other had a plug (so you could put the gauge on either side). I removed the plug and put a hydraulic brake switch for a motorcycle in its place. I then use a 12-volt wall wart to power an LED trailer marker light beside my exit door, right at eyeball height. If there is pressure in the air lines, the light is ON.

I can get away with this setup because my compressor tank is VERY air tight. With the valve OFF, it does not lose enough air to cycle the compressor for over a week. With the main valve ON and the valves at the four drops OFF, it will cycle after about three days.

My compressor is very tight and doesnt leak much at either. However the pressure valve did develop a crack one day and the compressor ran for hours. Enough that it filled the garage with smoke.

Here's my set-up. Powered OFF, when not in use.
