Rainbows in the Lehigh Valley Gorge

[TMo]

Had the spark of an idea last night before laying my head on the pillow.  My current lighting of Mud Run is from an overhead light which provides lots of light, but not into the area behind my bridge - everything's in shadow back there.  As you can see in the picture below (the real Mud Run bridge), there is substantial light behind the bridge which can highlight some of my scenery that (eventually) will be back there.

   

I'd bought some incandescent bulbs a few years ago with the intention of having some replacements for loco headlights.  Thought I was getting small LEDs (would have helped if I read the description closer) and opened the package to find 25 of these "large" incandescents.  
   

Decided to save them for something - and now I have a something.  As a trial, I wired one of these directly to my bus bar from my DCC booster.  Way too bright and I have to add some resistance tomorrow to dim the bulb and keep it from burning out too quickly.  However, took a couple of shots to see how it looks.

   

I'll pick up some resistors and a switch (I want to option to turn the light on and off) tomorrow and play around with how much light I want back there.
