Okey dokey, long story short.
One of my oil burners lamps flickers, sometimes goes out and then come back on. Makes people I'm overtaking on the motorways think I am letting them out !!
Sometimes it goes out and stays out but comes back on when the lights are switched off and back on!!
Getting the impression a 'loose' connection is somewhere as many times the light goes out when going over a severe bump!!
Any direction??
Many thanks in advance
