Instead of HID, try LED first. You can get a good set from Amazon. Pops right into existing slot and harness. 6000K is a perfect white with a bit of a blue hue. 8000k is too much I think.
Also, don't recall on the stock set I used to have (1SS-non RS myself), but on these Eagle Eyes, I can adjust the focus direction with a screwdriver. Its just a small screw head.
Lastly, look into the Eagle Eye set, go LED... and you're going to love the look.
Headlights (note from Hero... stamped Eagle Eye's when I got em lol)

Here's me with a set of 6000k LED bulbs on the Eagle Eye's... I've kept the halo's off for now because it looks more sinister this way, but its just a wire you tap into whatever you want...
eta, just noticed you've got a '15 so the eagle eye's are out lol... still gonna leave this info up for those interested pre refresh 5th gen.
