In 1952, George W Whelen invented the first rotating aircraft “anti-collision” beacon in his garage in Deep River, Connecticut, USA. These beacons rapidly earned a remarkable reputation for quality and durability, and he soon created a magnetically mounted beacon for ambulances and police vehicles.

As the company progressed, Whelen’s devoted workforce led the industry in technical and manufacturing innovations. The progressive philosophy that nurtured beacon advancement is also responsible for Whelen’s development of strobe technology in the 1960s, lightbar design in the 1970s, and LED advancement in the 2000s.

Today, Whelen’s advanced LED technology and powerful lights and sirens are trusted to keep people safe all over the world. Whelen is continuously innovating to ensure their products are of the highest quality, with the same passion and pride shown by George W Whelen over sixty-five years ago.
