The choice is pretty big tbh but depends on whether you want to keep an oem theme to the car or not?
If going down the oem route then for the front it's either gti darkened lamps, oem xenons or some of the hella oem xenon look halogen projectors, for the back the only option really is the ed30/r32 rear clusters,
If not oem then there are loads of projector / led type lamps for both the front and rear and wil just depend on how bad your taste is...
To get a HID kit fitted you'll just need to buy a full kit for the car from somewhere like hids direct or similar, imo they look and perform terrible when fitted in halogen reflector lamps especially when high up the colour range such as 8000k...
