does any one know y some audis have blue xenons and some have yellow i never actually found out y that is...Thanks

blue is HID - yellow are just normal bulbs ?

nicely said akielb. the yellow isnt xenon and if they told you that then check under their hood and see if where you would change the bulb has a high voltage warning and that will tell you.

Thanks guys for the input guys i appreciate it

i think he is looking at the projecter lens and confusing them for xenon. you cant tell by looking at the actuall projecter from the outside..
