I built a modulation light by soldering a #47 bulb to a pl259. The problem is that the light is bright when keyed and brighter when modulating. I guess that is really not a problem, but I think it would be easier to tell the difference in modulation if it weren't so bright with the carrier signal, because it is easier to tell the difference between dim and bright than bright and brighter. Any ideas on adding a resistor to dim the light some? In series or parallel? Please keep it simple for stupid (me). thanks.
