D3 Rear indicator LEDs keep blowing

[audifin]

Back in June my left side rear indicator stopped working, too many LEDs had blown. I replaced them all and it worked fine for about 3 weeks, then they were blown again. I thought maybe I had bad batch of LEDs or something and replaced them again, but now they've stopped working again...

So I wonder if the "control PCB" is broken and is now frying the LEDs? Has anyone had similar problem?

I replaced the rear light LEDs about a year ago and have had no problems whatsoever.
