I was a bit hesitant posting this in my blog, might be that I was pushing too many electrons through a connector pin. Or it might just be one of those self exacerbating connection issues. Either way I wasn't sure it would be helpful for others to see the failure. 

Anyhoo, complete low beam failure caused by bad connector on back of fuse panel.
