For more than half a century Whelen Engineering has researched, designed and developed warning and signaling devices. Whelen light and siren products set the standards for Police, Fire and Rescue, Emergency, DOT, as well as Maintenance and Construction equipment. Whelen built state-of-the-art aviation lighting since 1952 and our high power voice and
siren systems are heard around the globe. Whelen’s headquarters is located in Chester, CT, with massive manufacturing facilities in Chester, Connecticut and Charlestown, New Hampshire.
Whelen is the only US manufacturer of emergency warning equipment to still manufacture its products entirely in the United States. The use of robotics and a motivated workforce allow it to compete with off-shore products.
