Design and Construction of Improved Flasher Testing Apparatus 660391

This report describes equipment designed and built in the Motor Vehicle Devices Testing Facility of the California Highway Patrol, and used to increase laboratory capacity for testing of automotive signal flashers. The new durability test apparatus is capable of handling two or three terminal flashers in groups of 80 at one time, and uses two electronically regulated, solid state power supplies as sources of stable d-c power. The performance test apparatus makes it possible to obtain the operating characteristics of 10 flashers in quick succession through use of a switching control unit and a strip chart recorder.
