Here is the strange thing. I was at my dealers parts department getting a gasket for my Forester. There was a little sandwich board advert on the parts desk about the puddle lights in the B9. I thought, great they must have decided to offer them as dealer installed now. (why would it be in the parts dept afterall) Well the parts guy was clueless and did not seem willing to investigate any further than saying he didn't know anything about them. I was in a rush and did not want to press the issue.
I did look in the wiring diagrams of the SM and other places but could not find any reference to the puddle lights. I could be looking in the wrong place though. I think they would be a nice thing to have, maybe they will offer kits later, hard to say.
