156 headlights switched themselves off
Last light I was driving along when I realised that my headlights were no longer working, there was no bulb failure warning, moving the lights switch back and forth did not bring the headlamps back on. Eventually I was able to confirm that the side lights were still on, and I was able to finish my short journey with the front fog lamps on.
After I had finished my appointment I went back to the car and restarted it, the headlights worked fine.
I cannot expect the local garage to fix fully working headlights, has anyone an idea what happened, and how I can prevent it happening again? Driving around with headlamps that are likely to pack up at any time is not a comforting thought.
