I've changed so many headlights in my wife's 2012 Subaru Outback, I've lot count. It's a major PITA to pull out the inner fender well to even be able to get at them. What a horribly engineered design!!! No idea what causes them to burn out so fast, but German made Osram bulbs are the only ones that last past six months so far. There has GOT to be some kind of recall or class action on this POS car??? If it wasn't paid off so fast, I'd have gotten rid of it long ago.
