Buyers Products LED Cab Marker Strobe Replacement Kit Series functions just like your OEM cab marker lights, but these lights also strobe when needed to serve as warning lights. This kit replaces your truck’s OEM cab lights with versatile marker/strobes that swap between solid output and strobe functions with the flick of a switch. The durable amber lights are rated IP68 for dust and water resistance. Kits include the lights, an LED flasher, two switches, and all necessary wiring harnesses and connectors.
