Halo HID?
Silverstars usually last longer than the knock offs (got ultras in the highs/lows and reg silverstars in the fogs). They also have a year warranty to boot. Be sure to keep records if you buy them in case you ever need to use them. They're a clean white in color though, not blue. Not sure if any manufactures make a reliable blue.
Damn good articles to read here from a very knowledgeable source.
