Just curious how I can tell if my Acadia has HIDs. My option sheet when I bought the vehicle doesn't say that I have HIDs, Up close it looks like a normal halogen light with blue tint around the edges but at a distance its white with blueish/purple tint depending on the angle. When looking through my owners manual under bulb replacement It says the vehicle is equipped with HID headlamps and should be serviced by the dealer/retailer or a qualified technician. Are the manuals for the non/hid and hid the same? Sorry for the noob question but any info would be much appreciated.
