Well unless you want to retrofit and buy a good HID kit then I suggest you just keep regular bulbs in there. Sylvania Silverstars are great, those Xenon ones come with blue coated bulbs if you just want the look of HID. Thats basically what those two brands are for.
Me personally? I have 10,000k HID which is a bluish/purplish tint. Yes I know, ricer as hell but whatever, I like them and they illuminate better with my buffed out headlights, but they don't glare like most cheap kits (mine WASN'T cheap) and I have them set correctly so that they don't blind oncoming traffic.
Go with Sylvania, you won't be disappointed!
