Thanks, that site was helpful. I found that the Daytime Running lights are a 9005 bulb and the Fog lights are a 9006 bulb.
From that I found a white LED replacement for both of them on Amazon here:

I found this YouTube video on how to replace the Daytime Running Lights (2008 model is the same as my 2012 model):
