Default It just happens that the shape of the HID bulbs create light waves....

of light that reflect some bluish/purplish colors around the edges. And when you approach one when driving, the beam is more spread out, so it almost appears that sometimes the lights are Xenon. Hope this helps. 8<)

Default I'm guessing it has nothing to do with the bulb itself but the lens.

The non-xenon uses a projector low beam and it may be qualities of the lens that cause the bluish tint. I know I get that with my OEM Valeos.

It's called knife-edge diffraction, folks. Whip out those physics texts!
