## Description

Package includes: 1 gasket with 1 manual Compatibility: 2014 2015 2016 2017 2018 Chevy Silverado 1500 or GMC Sierra 1500 2015 2016 2017 2018 2019 Chevy Silverado 2500HD 3500HD or GMC Sierra 2500HD 3500HD Specifics and Features: The thickened and reinforced EVA Foam offers superior waterproof, dustproof, and shockproof performance. Constructed with high-quality cushioning material, the product provides flame resistance, chemical resistance, and excellent durability for long-term reliable use. Its dimensions are precisely engineered to fit both factory and aftermarket third brake light, enabling easy installation without modifications or trimming.

Tips: Stick new seal gasket with adhesive on the back of third brake light, pay attention to alignment. Ensure that the surfaces of both the vehicle body and the third brake light are clean prior to installation. Inspect the source of the leak; it is advisable to apply a clear sealant to the screw heads of the light, as water may be entering through these points.
