D-tub Lighting

I have some 12V metal halide fiber optics drivers I want to use, but need to get some plastic fiber optic cables, which could then be used next to the tub rim.  Fiber optics are the safest lights since the power source is a long ways away from where the light is used.

I'm sure there'll be LED lighting, too, but this will likely be one of the last parts to be completed.  I need to light all the nooks and crannies, but I don't know where all the nooks and crannies will be yet.
