I had an expensive HID kit on my previous car with headlights with optics in it (I don't know if that's the right english word for it, surry guys). However, I kind of feel like the Lexus OEM headlights with normal bulbs feel better on my eyes and make the visibillity in the winter season much more safe. I mean, you all know what 6000 HID kit makes you see in a rain or, god save us, fog. Almost nothing (compared to the normal bulbs I mean). That's my personal opinion off course.
