In my honest experience, all Sylvania bulbs last a good while. Yes, even the Silverstar line. I used them in the past (before I realized that blue-tinted bulbs are silly), even transferring the bulbs from one car to another, and never had a problem. I now use the XtraVisions and love them, and they have served me well in 2 of my cars now for some time.
