This tail light assembly set is designed to restore rear lighting performance and appearance on select Chevy Silverado and GMC Sierra trucks. It includes left and right side housings and is built with PMMA lenses for strong light transmission and improved visibility. The sealed housing is rated IP67 to help protect against water and dust in all-weather conditions. Its plug-and-play design allows straightforward installation with no drilling or modification required. Bulbs and wiring harness are not included, so the original bulbs must be reused.
