The M2 lighthead delivers high-intensity lighting in a compact design, making it ideal for fire, EMS, law enforcement, and utility vehicles. Part of our popular M Series®, the M2 features Linear Super-LED® technology and ensures bright, consistent warning illumination in critical situations. Its low-profile, rounded rectangular shape allows for versatile mounting options, making it ideal for a variety of vehicle surfaces where space is limited. Available in single- or dual-color models, the M2 offers flexibility for primary warning or scene lighting. Built with hard-coated, impact-resistant polycarbonate lenses, it stands up to harsh elements like sand, sun, salt, and road chemicals. Engineered for durability and reliability, the M2 is a top choice for fleets that need dependable lighting solutions in demanding environments.
