There has been much debate about these "ion blue" bulbs. What has so far been concluded is that the xenons are brighter white than the halogens so the blue tinge you see is increased scattering of the more intense white light by water molecules. Or something like that. Sounds like it could be true, but I'm not standing behind it. It's just what's been discussed.
Secondly, blue is the worst color of the spectrum for visibility in the rain as that wavelength gets scattered more easily. This I do believe.
But, what I do know for a fact is that the blue bulbs are illegal in the United States and since their increased popularity, law enforcement has increased. There is some law about not having the same colored lights as emergency vehicles.
I've seen a few E46's around in my part of the U.S. ( Northwest ) during the heavy rains ( of which we get a lot ) and the normal halogens are *excellent*. I wouldn't sweat it, and I wouldn't change the already functioning bulbs just to look cool.
: I called my dealer last night to ask if it was too late to add Xenon lights to the 323i I ordered 2/1. He checked the computer and said my car was already in production, so it was too late. However, he said that 1/2 of the cars you see on the road with the blue lights are regular halogens that have a "blue-green" coating on them. Anyone have these or know where to get them? I know they won't perform the same as Xenons (and probably not as well as regular Halogens) but I like the cool look. Also - I presume this is a good sign that my car is already in production??? Should I expect early delivery? (I was planning on May 1).
