Putco part # 401815 3rd Brake Light Cover easily sticks over the factory 3rd brake light giving it a custom chromed look. The third brake light cover installs with pre-applied 3M tape directly onto the factory brake light. It is made of ABS plastic with a chrome plated finish that matches OEM chrome perfectly. We recommend the ABS chrome over the stainless because the plastic can be molded into shapes that the metal can't bend to giving you a better fit.
