I'm confused. I bought replacement bulbs from Amazon that it assured me were correct for my car. After they arrived I realized they were the wrong socket type. I researched socket types and determined that my '06 Forester has an H1 socket for low-beam headlights, and a 9006 (I guess?) for high-beam. Anyway, I looked on some other sites including TireRack, and several merchants seem to be of the impression that the Forester uses the L-shaped 9006 bulb for its low-beam headlights. So why would my car, which we bought new, have a different kind of socket?
