Which do you think looks better? i want something dumb bright and white. some say the Catz are better, some say PIAA. I need help deciding! Catz are a lil cheaper too

 

I have seen both, although different type bulbs. One was on a Pontiac. The Catz appear slightly more blue while the PIAA are brighter. The best color is the Super Plasma by PIAA (lgt purple) but are not bright at all. Check out www.autobulbdepot.com for comparisions and pricing. If you do not want any coloring, reasonably bright, and 50 state legal bulbs, then look to PIAA's Platnium series.

 

the piaa xtreme whites look yellow, when you turn them on during the day.

right now, my xtreme white headlights went out, so im using these lame LUKZ metal white bulbs. when i have my fogs and headlights on, the fogs look yellower.

but the xtreme whites are real bright at night.
