yup, lots of people with colored cars do this to match the car...

also, like others said, its common to paint them black, to give them more of a smoked look without loosing any lightpower.

i'd like to do this to my Runner, but need to pick up some 'laser cut lenses' rather than the old 'projector' style i have now.... the 00-02 runners have laser cut but the 98-00 was projector.

I just havent wanted to cough up the dough yet
