Hello, that person retrofitted projectors into his stock or aftermarket headlamps. There isn't an HID (Bi-Xenon) ready headlamp available for the B16. However, there is a projector type headlamp on ebay/amazon but it isn't HID-Ready...
As you can see, it retained the 2007-2009 style rather than the refreshed model's style up at the blinkers. They do have an added DRL LED setup but it's quality varies depending on manufacturer. Usually people say to stay away from pre-made sets since the quality of build isn't the best.https://www.ebay.com/itm/Dual-CCFL-Halo ... US&vxp=mtr
Also, TRS (theretrofitsource.com) is a please where they have some high quality parts to retrofit projectors in headlamps. If you're not a hands-on person you could always purchase the parts and take them to a shop so they can paint/install your desired setup.
