um...im pretty sure that ALL Pro Stock cars have the factory headlights and taillights on them...i've been wrong before...but i'm pretty sure i'm right on this one! Look closely next time you go to a pro event...
This is true. A requirement of Pro Stock is the Factory Headlights and Factory Taillights must be used in the stock location. They cannot be painted on or decals.
But the question is... Do they work? I am thinking no!
On my cars they do...
