As one of the first owners of the black projectors back in 1999, my nis-knacks projectors have seen better days. I was wondering if the matrix racing headlamps were compatible with the nis-knacks corners. Does anyone know who sells a cornerlamp that would work with that headlight now? Anyone with the matrixracing lenses please respond, your input is greatly appreciated.

And the answer to your question is yes, i did search. I think it is compatible from what I've read, just looking for some first hand feedback.

For those of you who have the mossy nissan crystal headlights/lenses, any reasons I should get those over the matrixracing lenses?

The Matrix and Nis-Knax headlamps use the same housings. The Mossy corners are the same as the Nis-knacks corners as far as the mounting points go. So if you're going to get new headlamps and you have regular clear corners, get the Mossy ones. They will fit perfectly. The US style corners have to be modified and so do the headlamps(Matrix) in order for them to fit properly.
