Plug-in working crossing flashers

I created several of these plug-in crossing flashers. They all began as a standard audio mini-plug. The base of the plug was ground down to make the concrete footing. The inner connector shaft was soldered to the pole, and a piece of shrink-wrap tube formed both the insulator and the simulated mount at the base of the pole.

Note that the flashers are facing in odd directions; this is often done where side streets meet the road that crosses the tracks. The one below has three sets of flashers in a different orientation; it also has a bell, which is a slice of brass rod soldered to the top of the pole.

Image specs: These images were captured with a Canon 20D digital SLR.
