A dying LED does not flicker, just looses brightness (white lighting
LEDs do blink, but that is a thermal problem with chinese crap).

Actually they are white. Flickering is currently faint but perceivable
already.

 
The power supply (external or internal) may be oscillating; Change the
external supply or look for dry capacitors in the internal one (if any).
 

Will switch to batteries first and see if it changes anything. Thanks for
the suggestion.
