Upgrading ATS Headlights

I recently traded in my CTS for a newer 2016 ATS Luxury. So far I love everything about it, but if there was just one thing I’d like to alter it’s the headlights because they’re so lame compared to what I had on the CTS lol.

I’ve seen that the Premium trim has lights that are similar to what I’d like, so question would be do I need to replace the entire thing or can what I currently have on the Luxury trim be altered to have the same HID that the Premium does?
