After I saw the rear left signal light warning message, I checked my taillight and realized 6 out of the 10 light bulbs would blink occasionally; later on, all the led lights don't even blink at all when I turn on the left turn signal.

I replaced that taillight a couple weeks later and it was working fine for about 3 weeks, then the same thing happened. The signal light just doesn't work. I took one of the taillight apart and examine the LED panel (see attached). If I connect each board to a 3V adapter, the 2 lights on each circuit will dimly light up. So I was wondering what was the cause of the problem? Could this be caused by a bad resistor or could the light burnt out (both taillight have the same issue???)?

Also, is there any way for me to just buy the LED part? other parts of the light is working fine so I don't want to throw it away

Dalam, how did you resolve this?

sorry for the late reply... I haven't resolved the issue yet. Probably bring into a dealership and replace the whole taillight.

Any other suggestions?

Unless there's more circuitry on the back of the board or somewhere by the harness, it doesn't look like those LEDs are surge shielded. This I bet is what killed the bulbs. There have been reports on other models with similarly failed OEM integrated LEDs which I know are also not shielded. What you can do is splice in pulse resistors which will act as a surge protector and help protect the delicate SMDs. Similar to why you want to put a surge protector between your wall socket and your computer/tv.... big enough surge event can fry electronic components.
