Lighting for my small houses

Working on doll houses and miniatures I have developed a love for fiber optics. It started out back when I was making model space ships and using the fiber cable to light up the windows in the space ship. I keep wanting to get some for lighting my dollhouses, that way I can run a small strip of fiber cable to light candles and other items. Since many of the travel related dollhouses that I want to build are going to be in 25mm rather than 1/12th scale, the fiber optic cable would be perfect even for normal lighting on them.
