A bit of a twit ?

One of the benefits of the very mild weather we have enjoyed this December in the UK has been that I have had the car out more often.  However it gets dark early in December which meant I had to use the lights for the first time.  No problem - I just turned them on and immediately people started flashing me.  At first I thought it was because I was driving an old car, but I quickly realised that I was on full beam.  However I couldn't find the dip switch.  I felt very stupid, I had had old cars for many years.  Eventually I remembered that one old car I had previously owned had a floor mounted dip switch.  How daft did I feel?
