Check out the mTEC H8 35w (standard) - Golden Style bulbs. They look great and work well in foggy condition. I didn't go with HID, since bright/white fog lights will just glare back in my face in foggy condition. This is just the right look I'm going for.
Installation was easy. Just use your 2 fingers to pull the lower bumper grill, loosen the 8mm holding the fog light housing, slide the fog light housing towards the center of the bumper to unclip. Shouldn't take more than 5min. Be careful not to break the clips of the fog light housing, they're crispy.
It was a cheap mod, less than $30/set.
