That retail price they quote is bogus, you can get these at Walmart for $17. Probedude, these are just halogen bulbs, and although the lens looks blue they will not show up blue on the road, only a brighter, more pure white. They DON'T look blue on the road at all, you have to pay a lot more if you want that. Those posers you refer to probably paid $75 for their true blue bulbs.
Also, as a word of warning, unless you have put an aftermarket alternator in your vehicle, you should not exceed the recommended wattage. You could kill some expensive parts. Save up and buy some true HID's, these use 40% less power than halogen bulbs and last for many more years, since they have no filament.
