How about a billboard sprite shader that takes z depth from the sprite centre?

For now, I'll just try to offset the light points more, and put the more elegant solutions on the back burner. Thanks for all the ideas everyone.

Would using a PolygonOffset work with a meter offset? I believe PolygonOffset won't work for you when viewing the light at an obtuse angle, say from the side, and slightly in front of, the vehicle. In such a case, the further headlight would need a greater depth offset than the near headlight to in order to completely avoid intersecting the vehicle body. In general, whether PolygonOffset produces acceptable results or not varies depending on available depth buffer precision, and how you've set your near/far planes.
