My HID is 35 watts and the California law just states that a forward facing light be white, and under 65 watts. It says nothing about HID specifically and they are legal. Now here is the good thing, they make them in the 5000 and 6000k range, bothe fall within the spectrum of white. Many new autos are now coming with HID lamps, including the newest Shelby from Ford.
