Update: still green after many hours and the driver side ballast will flicker for a bit then "pop" back to full brightness.. this is in -5C to +2C temperature. The passenger side one (with the greener bulb (IMG:

I'm really getting irritated by the quality of these ballasts from mobilehid. In perfect weather they work fine. As soon as it starts to get a bit nippy, even though they're temperature rated for lower than it gets here, they fail.
The only thing I can possibly fathom is that either a) it's not temperature rated for anything below balmy, or (IMG:
