TL;DR - My Hella's are working again, and the problem wasn't the Hella's or the HID upgrade at all. It was my Bussmann relay/fuse block.The Hella's (and the related HID components) were never the actual problem.
TL;DR - My Hella's are working less and less now; I'm biding my time until the end of the year, when I hear that Diode Dynamics may have something fun coming.I'm not as happy with the HIDs in the Hellas as I was when I initially installed them.
