Fellows and fellaws:
Some time ago there was a subject running around about high beam led light
dimming to off.  I have just receive this fairy on my '84 Westfalia.  The
LED was coming on dimmer and dimmer each time until know it is impossible to
guess if its on.

I don't recall having seen a final determination on cause, possibilities or
cure for this, except that it was not clear if this was a bulb or an LED.
Can someone help?
