WHELEN ENGINEERING CO. INC.

For more than half a century Whelen Engineering has researched, designed and developed warning and signaling devices. Our light and siren products set the standards for Police, Fire and Rescue, Emergency, DOT, as well as Maintenance and Construction equipment. We've built state-of-the-art aviation lighting since 1952 and their high power voice and siren systems are heard around the globe. Whelen is the only U.S. company to still manufacture its products entirely in the United States.
