How to make a Backlit logo?

[alphime]

Hey all, I'm working in Max6 and I've modelled a soda machine. I want to create the effect of the machine logo lighting up like the backlight on the logo was turning on. I'm having some trouble getting the light to penetrate the logo surface and light it up. I was considering using self-illumination on the logo texture to make it "turn on" but that doesn't give off any light to the surrounding objects which is important. Any suggestions?

radiosity, if your not familiar with that than throw a directional light with the falloff really large right in front of it pointing outward + volume light, then instance the same light and flip it 180 so that it points tward the other light, after that in render effects add a glow to the logo weeee
