If you check out the thread above, you will find a pic I posted comparing the stock bulbs to my new ones.

My head lights are the Sylvania SilverStar's 9003ST, I ended up just buying these at the local auto parts store. They had a buy 1 get 1 at 1/2 price so I jumped at it, saved about $9.00 and didn't have to pay shipping.
