I got mine from Pinnacle in AZ. Not sure where you are, but if you're from Canada, get the parts from the US. OEM prices are less than half of what we'd pay up here.
FOG LAMP ASSEMBLY--make sure to order the correct side, left or right, as they are not interchangeable. There are some aftermarket listings on ebay, and I believe they are interchangable with FX35/45 lights, so check for both.
OEM worked out to the same price for me as the aftermarket items, so I went that route.
