With one pickup the lighting was blinking like a neon sign. So I found a reference from CTT. Bob Nelson suggested a capacitor with a bridge rectifier to smooth out the electric ripples.
Parts
Radio Shack272-1022 electrolitic capacitor, 35 vdc and 4700 microF
a little expensive and big.
276 1152 bridge recitifier rated at 1.5 amps and 100v ( the black round dot with the green wire )
Simple connections, I used a board, but it is not necessary. I even mounted the second light on the board.
The feed and ground wires are fed into the rectifier
The + on the recitifier is connected to the + on the capacitor.
The capacitor connections are fed to the light.
I did add another light. These are 14v screw base lamps 272-1134 rated at .2 amps.
