HID's, if the car didnt come factory, will auto fail you on safety inspections. You can pass with them in still but that ultimately depends on two things. One if the inspector really cares or not. Ive had some inspectors fail me in the past for my liscense plate light not being the right color, ive failed when the light displayed in my reverse lights is the correct color but the color of the bulb itself is not to the inspectors liking. The second thing that will likely fail you is the color, if you have blueish white or some color there of your more than likely gonna fail, if you get a set of bulbs around the 5K range you might be able to pass with them in. Im not sure the exact Kelvin temp of the bulb youd want off the top of my head so dont qoute me on the 5K. Now if the car in question is an BMW or some other European model that usually can come with HIDs than the inspector will more than likely not notice but if its a civic or something than you may be in trouble.
