Piaa

hey,
wondering if anyone knows the differences (if any) between the following:
PIAA Xtreme White Plus
PIAA Platinum Super White
and those White/Blue bulbs made by Hiper Industries

Are they pure white, or a bluish tinge to them?
are PIAA's worth the extra dough?

Im just trying to decide which blubs to go for

get the PIAAS

ive had all 3 get the superwhites
perfect white/teeenypurple

The Piaa's are fukin Bright, we have em on my moms LX450 and people on the highway think that you're highbeaming them, and then get behind us and they start highbeaming us, then we get behind them and show em some PIAA highbeams and they run away!!! its madd funny!
