I miss my GREEN dash blinker on indicator!

I have replaced all the blinkers, tail lights and dash lights with bright LEDs in my 65 Plymouth Valiant Signet convertible. I have also put the correct flasher in so everything blinks at the correct pace. But that green blinker ON indicator no longer works

Neither do those "bright LEDs" you installed in your car's exterior safety lights. See here and the sub-links.

(Yeah, I know…wet blanket. Wet blankets are real useful if you have a fire to put out, even if you weren't aware you had one.)
