Use of Solid-State Flashers in Heavy-duty Signaling Applications

Nearly every area of vehicle electronics is experiencing a design and implementation revolution. Drive-by-wire concepts, controller area networks, and “on-line” information systems are rapidly changing the way we view vehicle electronics. Advancements in technology enable improvements or even revolutionary changes in the way products are designed. Enhancements in semiconductor technology are enabling an evolutionary change in the design of products for all types of vehicles. Electrical systems are supporting the movement towards higher voltages, more features, and more power. Today, heavy duty signaling applications may have as many as 20 bulbs connected to the flasher, forcing designers to look towards higher reliability, solid state switching methods.
