Ugh. Please dont jump on the blue bulb bandwagon. They provide you LESS visable light than a standard halogen bulb, and they are significantly more offensive to oncoming traffic.
Just pick up a set of Sylvania XtraVisions or Silverstars
Some other interesting facts: Red light causes the least dialation of the pupil and is considered a safe light for interiors. Green is highly discernable by the human eye, blue is quite the opposite.

the eurolite bulbs are "blue" like the colored APC bulbs and stuff, they are actual xenon bulbs, like the 194's and the headlight bulbs and are very good quality, i have had their crystal fog light bulbs in for 6 months now with excellent output and white color and most of my interioir 194's are eurolite xenon bulbs and they are hella bright white, i mean almost too bright white they make the inside of the car glow white...kinda funny.
here is where you can find their full catalogue...
