No, not just extras 6 and 9, I already installed the fix for that, even after LODing them all, the driver's side half of the lightbar isn't working. I can still see the objects that would be the emissive lights, but it looks like only the ENV texture is showing. I got my game working again, so I'll include a few screenshots. It also looks like some of the lights are visible from different orientations. (90 degrees to one side- see driver's side corner light in the last photo vs the first one)
