## Description

Featuring a single-sided adhesive design, it allows for easy removal during bulb replacement or light assembly maintenance without damaging the gasket. Package includes: 1 gasket with 1 manual Compatibility: 1999 to 2006 Chevy Silverado 1500 2500 3500 2001 to 2006 Chevy Silverado 1500HD 2500HD 2007 Chevy Silverado 1500 1500HD 2500HD 3500 Classic 1999 to 2006 GMC Sierra 1500 2500 3500 2001 to 2006 GMC Sierra 1500HD 2500HD 2007 GMC Sierra 1500 1500HD 2500HD 3500 Classic Note: Does not fit Models 1999 Old Body and 2007 New Body 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. When replacing the bulb at a later stage, the gasket leaves minimal adhesive residue, significantly reducing cleaning time on the third brake light assembly. 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.

All emails will be replied within 24 hours. Your case will be taken seriously regardless of warranty period.
