I haven't read about it in a while, but last year when I was looking into Silverstars I was directed to get OSRAM Silverstars rather than the Sylvania. Apparently, they are made by the same parent company and sold under Sylvania in the US and Osram in Europe. The Osrams, though, don't have the blue tint to the bulb like the sylvania ones do. Not having this tint makes them brighter than the sylvania silverstar. I was convinced and got a pair on Ebay from the UK for about the same as sylvanias at Autozone after shipping. Now I've never had or seen the sylvanias, but these osrams are awesome. I am very happy with them and plan on sticking with them in the future.
