I have looked everywhere on the forum and all end up same answer.
After swap out all 4 turn signal to LED you will need 2 diode to block the power go over to another side from the indicator light.
so here is a link that a guy replace the indicator light bulb in meter with 10,000 mcd LED so it stop all 4 TR to blink at the same time.
Is it because the 10,000 mcd LED is a diode it self so it act the same as adding two diode to original indicator light ?
has anyone try it ?? or done it ?
I'm try to see if there is any other way than adding two diode and cutting wires.
