There was a thread from someone who had made his own halos from the clear plastic things that you use to open and close curtain blinds, and some LED lights. You would have to research in the projector threads to find who it was because I can't remember his name.

If you put two Projector sets... would you aim the highs alot higher, or would you aim all 4 at the same level and make the road as clear as day?
