This is a 16-lamp electronic flasher relay used to control turn signals and hazard lights on heavy-duty trucks, trailers, and other vehicles. It replaces older mechanical flashers and provides a steady, electronically controlled flash rate whether you’re running incandescent or LED bulbs. You would install this when the original flasher fails or when upgrading to LED lights to maintain a proper flash speed.
Commonly used in heavy-duty trucks and commercial trailers. Also suitable for vintage cars and trucks.
