lights. Because I see them on almost every 300zx. I just replaced mine last year with a brand new one nice and black. It's funny how many 300zx's I see that are faded. I've seen many 300zx's that are stunning from body and wheels to interior and you can see and tell that the car has tons of money into it but then the 3rd brake light is reddish faded and looks like shit. I then think to myself why not just fix it! Like they put all this money into their car but cant replace a $150 part. It makes a huge difference.
