PWI expanded into the electronic manufacturing business and, in 1972, PWI pioneered complete cold cathode fluorescent lighting systems for aircraft. The custom-made lamps were manufactured in-house. While maintaining the lamp manufacturing and coil winding business, PWI purchased the complete tape-wound bobbin core product line from Friskam Infinetics. These tape-wound bobbin cores can be used in special low-frequency transformer and inductor designs, magnetometers, and current sensing transformers.
