Allow me to add to the negative.
If you want the max light output, get the Sylvania Xtravision. It's the same bulb and internal gas charge of the blue-filtered Silverstars without the light-filtering blue coating, or the increased scatter and glare of "blue" wavelength light (esp in bad weather.)
Better yet, get Philips Premiums, $30/pair from
http://www.autooptiks.com/front.htm. Even more light output, and available in high and low beam.
There is no inherent advantage to high "color temps" or blue-white light, and "looking brighter" doesn't mean it really is brighter.
But, if you want that fashionable faux-HID look, the Silverstars are an OK choice. Get the Cool-Blues if all of your friends have them, and you want to be laughed at by anyone over the age of 25.
