I decided to do an experiment and try some really "warm" lighting in a set of Madison passenger cars. I used a strip of yellow LED's that I had purchased some time back to do this, I decided to give it a go. I think they look really good, much more like the shade of lighting that a prototype Madison would likely have. I'm going to have these at York in the Henning's Trains booth as the demo for the lighting kits, drop by and take a look. I also have a warm white upgrade that uses my standard LED strips. I may have to consider adding the yellow option.
