I put it this way. Dan generally provides good information, which is usually backed by documention and experience. I wouldn't call him the last word, even in lighting, that's going too far. That's not to take away from the fact that he is an expert in automotive lighting and one of the few in that field to have been so willing and generous to share his knowledge with automotive enthusiasts. All I'm saying is there have been times I've found slightly different expert opinions and that he himself has changed his perspective or conclusions over time. That he can and has done so is an indicaticator that he is a true professional.
