Hello,
I've only had a moment to skim your code, but you will need photons
to be able to have the light do anything after it reflects. I was
messing with something very similar a while back and wrote something
about it here that might help. Basically I needed to end up bumping up
my photons media parameter (though yours is probably plenty high, just
enable it) and really increasing the media samples.
Here's the message:

There's some other good suggestions in the rest of the thread as well.
This is the scene file when I finally got it working:
