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 and I do know why. There is not enough current going through the bidirectional LED in there to make it flash. I even tried an original incandescant too but no luck. Has anyone else dealt with this upgrade issue and made the indicator flash? I'd rather not go back to the less bright halogens or incandescents. Thanks for any help.
 
Are you sure you used a correct electronic flasher? Because what you are describing is what happens when the LED bulbs don't provide enough resistance to trigger a thermal flasher unit.
 
You might want to check the ground path for lights. Mine was weak, I ran another ground wire to the cluster housing to fix my issue.
 
I have tried an old incandescent AND a halogen but no luck. The Green LED is bidirectional but that doesn't help. Maybe Red 72's suggestion of a better ground may help.

@johnnyusa can you post a picture of your LED flasher?

This is the one that worked for me.

I'm going to buy and try one of the suggestions you've all made becuase i bet that extra ground wire may do the trick. I'll post a success or sad story later.
 
I had a ground issue sooo bad.

On a non mopar headache, The shift cable broke, so I spot welded some bar stock onto the shift shaft of the fearbox, and one day driving to work @ 2am I seen sparks against the flat stock and slice I made through the cab tunnel hump.


Ground is a real thing. Add them if in doubt.

Hehehehhe. Poor transmission PCM. Oh well. That was 5 years ago. Driven daily.
 

Ohh. The coil is fed off the alternator post.

Maybe that's that's an issue?

It charges even when near stalling.

No revving required. Seems like a plus.

I'm alsp dumping voltage without the ballist on 1.5 ohm. See where this goes after a few weeks.
 
Actually.

I think it should use two grounds.

Twice the amps is twice the power, right? Ohms law doesn't lie.

Few weeks just turned into 1 week.

Might I be thinking this right? If 12V appears after the flasher and all LED outside indicators work, might there not be enough current AFTER the blinking bulbs to run back to the 5V regulator to trigger the green indicator?

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.)
 
Old cars need older bulbs and flashers.

Only the digital world can survive LED installs.

And I want to baseball bat every idiot that stuffs LEDs in HID reflector housings.
 
I get it. Although everything works perfectly EXCEPT the indicator, I’m switching back to incandescent. LED is not ready yet and likely never will. Thanks for all the replies and tech.
 
UPDATE! Installed 1157 incandescent in the front and everythings works including the GREEN indicator and the LED red brake/running lights. Life is good. Thanks.
