What's wrong with purple? It's a great color, even for headlights, but at the expense of safety, which is never good.
one word: RICE
That is something you would expect on a slammed civic hatchback with a shit body kit and a 16 year old driver.
Being that his car came with HID's I would assume it is much nicer than what I just described.
it will hurt his eyes as well as other drivers with a huge loss of light.
To the OP if you want something more exotic than 4300K (white) go 6000K still very bright with quite a blue tint to them.
