The roadside flasher type MFLA2 is a portable explosion protected Ex ia LED based self-flashing lantern designed for general hazard identification in underground coalmines. The high power large footprint magnetic base makes it easy to attach the flasher to unserviceable vehicles or other underground roadway hazards. The MFLA2 may be mounted in any orientation. The MFLA2 flasher will continue to flash until it is switched off, but will operate continuously for six months on the one set of batteries.
