dash glo-light winked at me 2X !

[unkl300d]

'79 300D 137K miles. Well, oddly enough
the glow plug light on the dash
went on for 3-5 seconds then off
again shortly after starting up
the car and driving off. It repeated this again about
4 minutes later while in motion.
Anyway I pulled over and checked the glow plug fuse which was o.k., then checked
the fuse box and only found (coincidentially?) one red 16 amp fuse
to the auxilliary fan (aux.heating)blown.
Otherwise the start up routine is normal
with dash glow light going on then off
before ignition.
Is this 'wink' just that or do you think
it is communicating some forthcoming
need for mechanical attention?
It has never happened before.
Thanks for anybody's opinions.
Archives suggest that a 'flickering' preglow
indicator tells that a glow plug is about to go. Would the light 'flicker' if the 80 amp strip fuse were about to fail ?

apparently, a loose connection or rust can cause this, not to
mention a failing plug.
No further problem though.
