Thanks for a great lighting thread. I upgraded my stock bulbs this weekend in my 06 wagon to H3 - 55W Tungsram Gold for the fogs. Osram H7 rallye+65 for the low beams and Toshiba 9011 HIR bulbs for the high beams.
I can't believe how much better I can see road at night. We also adjusted the stock fogs upwards so they hit the road 20 feet from the car, they were uselessly hitting the road 5 feet in front (only helpful for seeing what you just ran over but too late to react), and aimed the low beams about 2" higher. If I start getting irate flashing from on coming cars I'll drop them back down a bit, but no trouble yet.
If you do any off road or rural driving, these bulb upgrades are great!
