Pretty sure the OEM ones are Sylvania bulbs. I know on the 8th gen were a LL part number - picked up some Sylvania 9006LL to replacement them, looks identical except for the gasket color (OEM was yellow, aftermarket was red/orange). Can't image they'd change for the 9th gen Corolla.
Personally - I didn't really like them too much. Sure they lasted over three years (were still working when I pulled them) - but didn't like the throw they had. Not enough light to see low objects close to the road surface. Switched to Cool Blue from Sylvania - shifted color temperature up, slight blue tint. Could resolve objects better, but didn't have a very far throw (blue light is more easily scattered - shorter wavelength). Those lasted about 2 years before they failed.
Ended up with Philips bulbs then GE Nighthawks - both I would consider superior to the Sylvania ones, in terms of visual light output for about the same amount of money. Silverstars (the clear ones, not the tinted ones) - might be the next ones I try. They last a lot longer than the previous Silverstars (some only got a couple of months life out of them, most didn't even make it a year). Made in Germany - better QC and construction.
