do they make clear corners that are Totally clear like ones that resemble the headlights. not the cloudy opaque diamond cut ones?

and where can i get one piece clear headlights?

 

I don't think so.. They still have to be reflective so totally clear ones won't do the job. There are however Diamond cut clear corners available which are a bit more clear looking than the regular ones but not clear like the headlights are. About the one piece clear headlights, I doubt there are any made, but look for a member "SYCEFIRO" he coverted the front end of his Maxima to a Japan-like Cefiro, he has 1 piece headlights, but this would involve more then just swapping the headlights, you may need a new grille, bumper etc..

 

I think the 1 piece lights would only fit I30's
