Code 3 incorporates PriZm II technology in a full line of perimeter lights. PriZm II advanced dual reflector LED technology provides a brighter signal for superior visibility and safety. This design captures and concentrates the light more efficiently, which results in a warning signal twice as bright as comparable reflector lightheads. PriZm II Perimeter Lights are available in 3 inch by 7 inch, 4 inch by 6 inch and 7 inch by 9 inch models with amber, red, blue, white or green LEDS, depending on the size and configuration. Perimeter Lights with PriZm II 12-LED lightheads feature an option for two-color combinations behind a clear outer lens with a left/right split flash pattern. Design features include the ability to steady burn, dim and synchronize between multiple lightheads. Perimeter Lights also have field replaceable outer lenses in amber, red, blue or clear and water resistant seals. LED PriZm II Perimeter Lights are applicable to installations requiring NFPA, SAE J595, KKK-A-1822F and California Title 13 when properly configured.
