In the "FWIW" category ...
Ever since I've owned my 95K mile 2008 Limited, I've had the 'fog' button pushed such that the fog lights always come on with the headlights. Have yet to replace either of the factory bulbs.
Man! You're lucky! Or what did you do?? Many of us here keep changing them, it's been posted many times.

Whoa!
The original fog is a 27W PG13 (
not PG
J13) in a 2009 Limited, so check again and get the right replacement in mind before you pick up any bulbs. The "J" versions run the connector off at a right angle. The original has the connector on the same axis as the bulb ('straight'). Looks to me as though the
#899 would be the higher output and longer life sub for the existing bulb.
So this means people in this thread were wrong. 881 were mentioned to whole time. But you are right, in my 2009 SF Limited owner manual, they mention PG13 base. So 880 is the exact replacement.
There's been discussion about replacing the factory bulbs with the 37.5W bulbs before. Unfortunately, members haven't given us any long term reports on the results if they made the switch. That said, I don't recall (yet) anyone saying they've melted anything, either. Work through the threads (some are quite old, and may take some digging) to see if you don't find that to be the case, and if you DO switch to the higher output, please let us know of any ill effects you encounter, OK?
