Well, the other night I was traveling back from Birmingham, AL and I noticed that my xenons don't appear to be as white as they once were. They have more of a yellowish tint to them. I have a little over 2300 miles and I was wondering is this normal for the lights to do this the more and more they are used? When I first turn them on they are still a blueish/white color but, as they warm up they start to look more like halogens but nothing like the fogs. Does any of this make sense? Hope so. All responses GREATLY appreciated. Please state if your Xenons look like this.
