The DRC series has been our premier model and is the result of over 10 years of experience in the LED lighting business. It features high-performance CREE LEDs, patented reflectors, and an industry-leading lifetime warranty. Like all Speed Demon Lights, these light bars are waterproof, dustproof and vibration resistant so you’ll never have to worry about the extreme conditions you put them through. The DRC Series comes in two options, Silver Ops & Black Ops. Black Ops series light bars have the same performance as our regular DRC lights with a sleek blacked out look. An H1 or H2 wiring harness is needed for installation, sold separately
