Abstract
Disclosed is a method and apparatus for reducing radiated interference from a light source wherein a filter device is coupled across the light source after a predetermined time has expired from the starting of the light source. In this way, the filter does not interfere with the starting of the light source, however, after being coupled, the filter prevents radio frequency interference generated by the light source from radiating from the light source and associated wiring and interferring with nearby radio receiving equipment.
