Just your luck again:)

For optics simulation, go for some optics package. I have no experience 
there though.

For your problem, I'd glue five blue leds to the inside of this flashy front
panel. Or alternatively, try covering the guides with reflective material.
Standard household aluminum foil should do for testing, and comes a lot 
cheaper, easier and faster than IDL.

Have fun,
