Not sure if you want the "bluish" look or not but the best bulbs to buy are Silverstars. Buy a pair of 9005's and cut out the little tab inside, real easy. The wattage of the highbeam is 60w compared to 51w of the lowbeams. The difference is amazing, you will not believe the difference. I did this to my Tour, before I got HID's and recently did this to my winter beater, you can't beat it. Theres no danger of hurting your headlights or wiring either, many have done this and been running them for YEARS
This is a "must do" mod to any car that runs the 9006/9005 set up
