Thanks for all the replies and ideas.
I wound up using Woodland scenics Just Plug Leds. I liked them because they are flat and have adjustable intensity. I removed the bulb and cut the cord from the light holder clip that comes with the building. I used a 3/8 inch square piece of wood about five inches long. I trimmed one end so that if would fit snugly where the bulb normally screwed into and placed three LED's - one on the front side and one on each side of the stick and inserted the clip back into the building. There was plenty of extra rom around the clip for the LED leads to extend fro the bottom of the building. I wound up with much better and more even lighting of the building and by adjusting the intensity, achieved the look I was hoping for.
There are several other building on the layout that I plan to do the same thing with.
Happy railroading,
Don
