Best sidefiring fiberoptic LEDs for weaving through a steel plate, cut to have a specific design

i’m currently doing an art piece that requires side-firing fiberoptic LED rope lights that come in as long of lengths as possible, and are roughly 1/8 in in diameter. Also, if that same company has endfiring fiberoptic led lights as well, plus. i need them to be compatible with pixelblaze motion and sound sensors and controls. Please help, this is a time sensitive matter.

Kind regards,
