It was good to catch up with the regulars (and the irregulars) but when it came time to leave I found that the light switch was behaving a bit weirdly. It felt unusual and although the sidelights came on, the switch wouldn't stay on the headlight setting, it just pinged back to sidelights. The next times switched it there was nothing, no click, no lights. Damn!
So a quick rummage in my tool box produced a switch but not the right type, I could get either side lights or front head lights only. Clamping all the wires together worked and I was able to get home to order a new switch, I've been successful in fixing these sort of things in the past but it's clear a spare is worthwhile having.
The price of these things seems to vary hugely and a new switch seems to be anywhere between £15 and £50, the TR tax applies although this is a switch that looks common across the range.
