A few months ago I replaced my standard halogens with Silverstars and to be honest, I wasn't really impressed. They are a bit whiter and brighter, but not worth the $40 a pair in my opinion. I didn't notice much difference driving at night. Nothing compares to true HID. Also, they blew out after 1 month, both at the same time! I wouldn't spend the money on them, but that's just my opinion.
