I have purchased led 57884-4.. It worked great for 3 months.. But since one week ago one of the leds doesn't 'light' up as it should. I've tried changing the 'bulbs' but the problem persists on that one socket (so it's not the bulb's fault).
Does anyone have any idea?
EDIT Yes sorry, I've included URLs - the images were too big and no, I'm currently located in France.
