The Whelen M4 Series Linear Split-Color Super-LED is a compact rectangular warning lighthead built for tow trucks, wreckers, and recovery rigs that need to be seen on the shoulder. Linear Super-LED® optics push high-intensity warning output from a low-profile surface-mount head, and Dynamic Variable Intensity™ (DVI™) automatically dims for night work so you stay visible without blinding traffic. Split-color models run two warning colors from a single head.
