They're actually not crap, and it certainly hasn't been "proven"... I've always spent a lot of time researching purchases like this, and the Silverstars do the job well.. Are they as good as the Euro version? Not even close. Are they better than most of what you can buy here? Definitely. Lighting needs also depend on what kind of driving you are usually doing. If you're going to be in a high-fog/high-moisture environment, a white light is not ideal, you're better off with a less intense color. But for what I do here, they're great.
The bulbs also aren't tinted. In fact, the bulbs that come with the IPF 900MSRs are more blue-tinted than these. They're a step past the XtraVision bulbs that I used to use. So do your research before bashing stuff like this. If you'd like to refute me, please do. But I'd love to see some proof (comparison, numbers, etc.)
