Sylvania Silver Star (not the ultra) should be fine. Bulb type 9005.
To be honest with you, what I would do is go to your favorite part store and buy a set of Silver Start Ultra for the low beam (9006) and a set of Silver Star for the high beam (9005). This will cost you about $90 and should saitsfy your road lighting needs. If you really want HID though, find a set you think you'll comfortable with off eBay and put them in the low beam slot (9006), and wait to buy new high beam bulbs. I know of a lot of people who don't need to use the high beams because they put in HIDs and they were so much brighter than the factory high beams.
