I was wondering if anyone has used Fiber Optics in their structures or locomotives with a DCC or DC power supply? If so, which manufacturer did you use? I am planning on re-doing the lights on a few Athearn locos and would like to use fiber optics rather than a bare bulb in the cab. Or should I use the Athearn bulb then attach fiber optic cable to it? I am planning on using fiber optics on my structures for lights. Any suggestions on what to use? Thanks to eeryone in advance. Sincerely Jaijef PS--i can run either DC or DCC on my layout.
