Hey Bruce! The headlights were tinted with a vinyl overlay from DecalFX.com. Here is the exact product I used:
DECALFX.com! Smoked Headlight Film Tint Overlays Vinyl Decals Stickers Lens Protection for Head Lights, Fog Lights, Foglights, Tinted Smoke Windscreen, Lens Paint
It applies very easily since out headlights are so flat on the front.
Bruce, I can't thank you enough for the compliments on my car. I REALLY appreciate the kind words. It means a LOT hearing things like this from fellow TR brothers out there. I had been wanting a GN for over twenty years. For that entire time, ideas ran through my head on how I would build one. Finally in late 2008, I picked the car up from it's second owner. From that point on, this has been the most fun car I have ever had, hands down...
