The Edwards 125 class incandescent beacons are UL and cUL listed signaling devices, available in two versions, flashing and steady-on. Both versions feature a corrosion resistant type 4X enclosure and can be panel or conduit mounted. The base is manufactured from a 33% glass filled nylon, providing high resistance to heat and high chemical resistivity. Both the flashing and steady-on beacons are available with either a black or gray base and amber, blue, clear, green or red lens.
