They're PIAA 510 driving pattern (not fog) with "super white" bulbs in them. They're available on amazon for $145. Just be sure to get the driving pattern as I've heard that the fog pattern is so diffused that it's relatively useless. I'd definitely have no qualms at all about using these as my primary headlight. At 55 watts each they throw a healthy amount of light. I have them wired up to my high beam switch via their own relay as my primary headlight doesn't have a high beam. My "highbeam" is my regular headlight + PIAAs.
