Sorry if this has been covered before but can't find another topic with the exact same issue.
I have a 1994 (used to be a Mayfair, converted to Cooper but I don't think the wiring has been changed) and as I got into the car last night I went to turn the lights on as normal, however they didn't turn on, neither did the sidelights. The rear lights worked fine. On the dash the high beam indicator is illuminated, but the stalk is in its correct position, again the high beam lights do not work.
This has occurred once before, I left the car for 12 hours and it worked fine the next day, however when I tested it today it was in the same state.
Any help or ideas would be much appreciated.
