From what I've seen you can get something fairly close to HID/ litronics by using a high output 100/80 watt bulb. However, you will only output about 1400 lumens on lowbeam compared to maybe 2500-3000 on a HID system. You may need to upgrade the headlight wiring harness and I don't know how long they last.
I would choose
http://www.sylvania.com/auto/silverstar.htm since I rarely drive at light. The output color is whiter and you don't need to upgrade your head light wiring harness with a 60/70 bulb.
