Federal Signal's Starfire strobe warning lights are available in single-flash (131ST) and double-flash (131DST) models. The base of the light is made of corrosion resistant anodized aluminum. Each Starfire model comes with a standard 1/2" NPT pipe mount. An optional surface mount kit 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, Models 131ST and 131DST warn of hazardous conditions, mark dangerous areas (either permanently or temporarily) and mount on lift trucks, cranes and other moving devices.
