As others have mentioned, I would highly recommend Sylvania Silverstar Ultras. They retail for $40-50 USD per set, and they last a decent amount of time (just make sure you do not touch the bulbs with your fingers, as the oil from your hands will cause problems).Here is a link to a photo of a car using regular halogens and the new Silverstar Ultras:
