It was modeled. Nothing too complicated but I get better results on the refraction if its modeled. As you can see I beveled each quad a very small amount with the offset being almost nothing. The bulb is a bulb shape and the inside of the frame is reflective.
After that I used LW's built-in dialectric material which does a good job simulating glass and used a refraction index of 1.52. I got that from some website I don't remember about headlights.
