Aircraft Warning Lights for Superior Paper

Two entries in one night after a long dry spell, talk about a 180! Anyway, I'd been kicking the idea of adding aircraft warning lights to Superior Paper for a while. I have a bunch of 3mm flashing red LEDs laying around and used them for the same purpose on other buildings. However, in this case, adding them to the tops of the stacks would have been too obtrusive and also a monumental PITA.

My bright idea was to run fiber optics through the stacks and under the layout, where the blinking LED would be located. I started out with running the fiber optics through the stacks and CA'd them on each end of the stack. Them it was simply a matter of drilling through the table and connecting the fiber to the LED. That was no easy task, but I got at least one stack blinking.

The effect is pretty subtle but I think it works and the fiber is nearly invisible when the room lights are on. Now back to that drainage ditch...
