I've spent a lot of time looking into lights on the Evo V/VI! Here's all the options I've found:
Ralliart, probably the HID option that is available in Japan, which uses the Cibie conversion. It only replaces the headlights and not the indicators.

As well as doing a headlamp conversion, Cibie also do a fog conversion. It is however a complete ripoff, it would be cheaper to buy the Ballasts, Xenons and Projectors seperately.

M'Technic, replaces the whole light cluster, with a choice of Xenon or Halogen bulbs. They don't look like projectors to me though:

Upauto, major flaw, their triple conversion doesn't have side lights, just indicator and split main/dipped lights. All using Halogens.

The Mirage in the US is the same bodyshell as the Evo V and as the V light cluster is the same as the VI you can interchange them. I've found a couple of sets:

I've come to the conclusion that there's not a lot out there, so I'm resorting to building my own.
A couple of things to bare in mind:
6K Xenons are completely illegal on UK roads due to the purple tint, which causes afterglow . 4.1K's are legal.
'E' lights are also a requirement on UK roads, due to the spread pattern. US lights tend to light forward, European lights more to the sides.
Xenon's for main beam is not a good idea, they don't take to being flashed or rapidly turned on and off. They also take a fraction of a second to warm up , which isn't good at high speed. Stick to Xenon's for dipped only.
To be completely legal, Xenon's must be self-leveling. When initially turned on, they need to level to the current weight distribution in the car. They are also supposed to have a cleaning system.
Finally, aligning Xenon's isn't easy, the top of the beam needs to be 2.5 below the horizontal line off the lights at 25'. After fitting them go to an MOT centre to get them aligned, it's easier.
