pretty much any HID kit higher than 6k will give a blue effect. 5k and below is what most imports use in they're HID's these days. my 10k was more like white with a hint of blue if you look at it head on. from the side it looked white as can be. bright as hell...but still white. if you think it's too much for you, black out your headlights. the chrome housing enchances it. the black housing takes some if it away.
i guess cop issues may also depend whatelse is also done to your car. I had absolutly no problems going anywhere with my car. slammed to the ground, rims, aftermarket body parts, etc. and yes...this does include waikiki. if you try putting HID's into your PRE-2000 car. it better be something highend like a lexus, bmw or someshit. idiots who put 12k kits into they're 95 civic is asking for trouble.
i say run whatever you want. it's your ride. just keep in mind the pro's and cons of getting them. if you don't give a rat's ass, go as bright as you want.
