The guys in the electrical shop at work were cleaning out a bunch of old stuff. I looked in the bin of stuff to be trashed and found this nice Allen-Bradley stack light.

Completely gratuitous, but I'm going to wire it up to the alarm outputs on my PIDs, so I can tell everything's fine from across the basement.
This particular unit is 24v ac/dc, so I'm just sticking a little stepdown transformer in the stainless box. Only pulls 35mA per light, so I can use some thermostat wire to provide the 5 signal lines I need back to the PIDs. The way it works is that there's a wiring block in the base, and you stack the lights based on the terminal wiring (1 goes to the bottom, 2 to the next, etc. ). The light modules are all interchangeable. No wiring needed beyond the terminal block at the base of the stack.
