I had Piaa Super Whites in my car until one finally croked early this spring. They had been in my car for about 6 years.

I went to the Silverstars and they didn't seem as white but I wasn't totally sure. Well, after having the Silverstars in my car for about 5 to 6 months, one blew the other night. I wasn't very happy in their longevity. Being in a hurry, I grabbed the other Piaa and installed it quickly so I wouldn't be late for work. Seeing them side by side, the Piaa was definitely whiter.

But I will say this, the Silverstars are definitely less yellow than the OEMs.
