I don't care if the light point occludes objects within a few meters. 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.
