HID LIGHTS Conversion

Hi, I just get a new Tahoe 2015, my trim is LS, (got it because is the one without the captain seat), I got the regular Yellow lights, and I have try to get the originals HID lights, as far as I have been tell, I can not get the GM part, because it came with different configuration from factory, and its impossible to get the parts or make the conversion with GM parts, its this true?, can some one recommend the best HID lights that its friendly with Chevy?
