I think if the chrome is removed from the face of the tailight(the part around where the bulb projects light) it would give the tail light a darker appearance. It wouldn't hinder light out put and would be alot different from what everyone else is doing
I would also love to know. Both my 2012 tail lights had the plastic bulb cover that is inside my light break off and is floating around. Used lights are only 100 bucks so in probably better buying another set.
I was looking at mine and i would love to be able to mod them. Basically pop the cover off, remove all red. Use red lights. For the sequential turn signals i would love to be able to use a CFL/LED square strip in each. But i don't think what i want exists.
