Stop Indicator issue - Not working

[KANDY]

Hi all,
I give up, please help out. 1974 RD350 Stop Indicator not working as it should. When Ignition on stop indicator also on ( Not solid on but pale)
When I hold the Brake, it go off (suppose to be happening opposite way) This RD is converted for LED and was working as it should until last weekend after a 120 km Ride.
This RD has Coil Relay MOD also
I changed this bulb to normal one it never on. I checked all continuity with the wiring diagram looks good, only the light checker I dont know how it works.
Please some one put some info on this, I will be going back to normal bulb just check the LED conversion was the issue in the first place.
A video is uploaded to explain the issued

well, it wont work with an led correctly as it needs the resistance. cant say as i've ever seen one go bad, but id replace it. its not serviceable.  pretty sure there's just a diode and a resistor in there.
