Our LED third brake light is a quick and easy way to dress up your pickup truck. When lit, the bright LEDs (Light Emitting Diodes) are illuminated, and shine up to ten times brighter than standard light bulbs. Even when the brake is not pressed, the integrated cargo light (if equipped) gives off plenty of white light to view your gear in the truck bed. The LED third brake light has a durable Polycarbonate Lens with free form reflector, and available with either the Clear lens or custom Smoked lens.Includes: 1 X LED Third Brake LightCompatible with 03-17 Chevy Express 1500 2500 3500Compatible with 03-17 GMC Savana 1500 2500 3500100% Brand NewProfessional Installation is Highly RecommendedInstallation Instruction is NOT Included Please Note: Highly recommended to use hand tools for installation.
