Starfire strobe warning lights contain their own strobe power supply in the base of the light. The strobe flash tube is mounted in an eight-pin octal socket base. The Fresnel dome stands up to impact and abuse and is available in amber, blue, clear, green and red. The base of the light is made of corrosion-resistant anodized aluminum. Each Starfire model comes with a standard 1/2 in NPT pipe mount. An optional surface mount can be ordered. Because of its convenient size and intense light output, the Starfire strobes can be used for multiple applications. Excellent for in-plant use, the models 131ST/DST warn of hazardous conditions, mark dangerous areas (either permanently or temporarily) and mount on lift trucks, cranes and other moving devices. These powerful strobes can be used on emergency, utility, maintenance or other vehicles requiring emergency warning.
