Everyone who has done an EvoXR upgrade on facelift lights and shared their opinion has stated it was a marked improvement.

There are pics with before and afters here and on hidplanet so you can judge for yourself.

X5snd has said (IIRC) you will need to do some mods to the wiring as the separate igniter is not compatible with the EvoXR bulb socket area.

Other things that can be done would be to check for crumbling wire insulation of the headlight harness, and headlight lens restoration if needed?

Not a fan of the blank space when removing the orange reflector, I am thinking it may be possible to cover it with silver reflective tape?

Oh, and stealth bulbs for the corner lamps! Subtle but noticeable. Cleans up that area a bit.
