replacement of the indicator with an LED will be inconsequential to the rest of the circuitry. (OEM or otherwise)
I'm wondering if your new trafficator LED units are making proper contact in their sockets .......
Just to verify ......
1. You have installed the diodes, the original trafficator bulbs, and everything appears to function nominally.
2. You swap out the trafficator bulbs with new LED replacements and they do not light up. Also, the indicator does light up - but does not flash.
1. Installed Diode Correctly, all the original incandescent bulbs work, blink correctly and the indicator also lights up and blinks as normal.
2. Once the LEDs are put in, ( i have tested and checked that the LED,s work once again ) they do "NOTHING", just dead.
BUT the Indicator light does light up and NO it does not flash.
Just 10 minutes ago I rechecked the process. this time i only put the LEDS on the right side and on the left side the original bulbs, the right side did not light up and the indicator lit up and did not flash (the LEDs are firmly seated in the socket which has a spring to seat it tightly, it's a solid contact both at the bottom and the side where the wire makes contact with the inside socket).
The left side worked fine and the indicator also blinked as normal
