Moflash Signalling Ltd

Moflash Signalling Ltd. was formed in 1958 as part of the Silvaflame group. In the early years, the company was predominantly involved in the manufacture of traffic safety beacons, however, they soon expanded their product range to include industrial beacons and led the way by becoming the first UK company to produce an AC rotating beacon.

Moflash was purchased by the Kentermark Group in October 1997 and moved to Birmingham. It now boasts one of the largest visual signalling ranges available in the marketplace, offering Xenon, Rotating, Flashing Filament, Static Filament, LED and EXD Beacons. It continues to develop new products to meet the demands of a constantly evolving safety market.
