oh my god.. no seriously...

-=breathes=- okay here we go.
the link you put up is to a set of overpriced 75 dollar light bulbs, with a fillament.

what top psi is selling is a tru HID kit. High Intensity Discharge. Its an arc lamp basically, no fillament.
it will outperform those simple bulbs by such an order of magnitude you won't beleive it.
that and the bulbs will burn out, the HID kit won't. sure the ballast might go bad at some point but you can get that lifetime warranty and you are good.

okay, so bulb = honda (sure, it gets the job done)
the HID kit = .. well a cadillac (gets it more than done, with style)
