well i use to have the regular silverstar. not so impressive because it wasn't so white, still yellow, but bright yellow, really bright. But friend had it in his rx300 and they burnt out pretty quick, maybe it was just the car.
But if you're willing to spead like 90 more just get some cheap HID from ebay, i installed mine today and man do i love it. hahah

thats the one. good reviews, and cheap too. Much better than silverstar. IMO
