I used these. They are a lot better than stock , and can be bought at any parts store or Wally world.
Keep an eye out for the group buy here for the tru HID lights. They are great.

Been using these since SWIII when I think HogWild turned me on to them. Work great for 1/10 the price of DayMakers. Some reviews claim they don't last very long, but I've probably got 15,000+mi on them in the bike, and I've put some in my car and truck as well with no issues.
