Default Why does audi use yellowish xenons?

I know this has been covered in the past...but, everytime I'm next to a BMW, Acura, etc etc....their xenon's look so much nicer. They are more blueish/purplish but, I like it...it just looks more white.

What do I have to do to get mine to that color? I know I've found before threads that say we have to replace our bulbs with a different bulb, but I can't find it now...

Anyone else think our xenons don't look xenon?

Default I don't buy a car based on the color of the headlights, nor do I particularily care.

Are you SURE you have or are referring to HID lights? I've seen plenty of Audi HID lights, that are certainly blindingly bright, and blueish.

Default All xenon bulbs will yellow with age. Besides, really blue HID's look ricey.

My Audi HID's are just as blue-white as my Acura's and both are still on factory bulbs!

Mine are blue when they are first on, then go more white as they get brighter. More blue head on.

Default Yes, I do. The xenons in my 02 are way different than in the 99..not as bright as well.

I think they changed them partly due to me. I was one of the first to get xenons right when they came out and got pulled over repeatedly because of it..One actually went to trial and I had to involve both my dealer and AoA in the case.

Default 4300K has been chosen for the best light output of the bulb...

...as you go higher in the Kelvin rating, you change the color emitted, but lose light output.

You can go up to 5K/6K, but that's the max before you start losing light output.
