I had the Sylvania Silverstar Ultra on my Chevy Cobalt and BOTH burn (1 week between each other) after only 1 year and 2 month. When I bought them many people warn me they burn quickly even if they are pretty expensive and this is true.
In the other hand, they are very good bulbs, bright, ultra-white look, better overall night vision so I do recommend it anyway, but be warned they don't last long for the price!
I'm just in the process of shopping a set for my newly acquired Jeep!
