Quote - it looks REALLY good there, what color did you use for the material behind the glass?

I didn't really use any color behind it.  I'm guessing that maybe its the material of the headlight casing?  Which in that case it would be your old chrome material.  I guess I could try rendering with the headlights completely transparent to see what's behind.  I'll do that when my current render is finished.  I do know the lights took a long time to render, but the results were definitely worth the wait.
