Perfect fitment: The Stealth LED Light Bar Kit for the 2015-2020 Chevrolet Colorado from Diode Dynamics allows you to easily mount a 30" light bar in the factory lower bumper opening. These application-specific brackets were CAD-designed to install using factory mounting points. No cutting or drilling required! This kit retains the factory lower grille for a clean, OEM-like appearance. Designed For Performance Using optical simulation model'g, Diode Dynamics Stage Series light bars have been designed for maximum functionality, with compact size, custom-engineered TIR optics, and a useful beam pattern, all in a highly durable package. Our light bars shine light in a highly-functional and useful beam pattern, much more focused than older LEDs on the market. Functional Patterns All Stage Series beam pattern options were designed with optical simulation model'g, to shape the output in a highly-functional beam pattern. No matter what your auxiliary lighting needs are, there is a Stage Series optic for you! The Driving pattern was designed to supplement your high beams. Rather than a simple "spot" pattern, the Stage Series Driving pattern has a rectangular 20Wx8H degree pattern that is far more useful for directing light downrange at high speeds. The Flood pattern was designed to provide uniform, even illumination and a full 80Wx50H degree spread of light. Unlike generic "flood" light optics that are simply a heavily diffused spot, our flood optic is a true optically designed spread, resulting in the biggest spread in the industry! It is perfect for lighting up anything at low speeds, a backup or reverse light, or to light up a worksite. The Combo pattern combines both the Driving and Flood optics. It shines light downrange in a focused, rectangular 20Wx8H degree pattern while also illuminating area around it in a full 80Wx50H degree spread. The Stage Series 30in combo Light Bar features three driving lenses in the middle with two flood lenses on the outer edges.
