Headlight Bulbs

I am looking for some bright headlight bulbs for my car. I see tons of people driving around with bulbs that look like a bright blue/purpleish color, these are the ones I am intrested in. Can you give me a site or name because last time I purchased some bulbs the package said "Cool Blue" they were just plain bulbs BUT they were a little bit brighter then the stock ones so I just kept them:p . So I want to change them again. Thanks alot.

Hella 9006 + 9005
Sylvania Silverstar Ultra's 9005 + 9006

McCulloch 8000K HID kit... http://www.xenonpros.com/mc8000k.html

For the Hella 9006 + 9005, do I just get the bulbs or do I need the whole kit?

Bulbs. We sell regular hella 9005 + 9006 halogen bulbs at Advance Auto parts. Currently they are 25% off, normally they are $44.99/pair. They are more white than anything. The silver stars have a slight blueish tint to them. I have those in all my cars, including my parents. Except the HIDS in dad's A4.

i use silverstars in my projectors and they do a great job.
