Super-LED Linear light heads feature new, patent-pending optics designed to provide greater light output that rivals strobe in intensity. Surface mounted light heads are vibration, moisture and corrosion resistant for long-life, heavy-duty performance and retrofit existing light heads. Now you can choose certified, legal lighting for fire service or emergency vehicles needing to meet critical specifications. Includes 13 Scan-LockTM flash patterns plus steady burn and low power control, an industry first. There is no need to add a centralized flasher(s) when using these light heads.
