Last stop was because one front light was ever so slightly less bright than the other which was brand new. It was just before Xmas and I sad driving home after work. They were taking any excuse to stop people for various checks. Police for drink and drugs if they can detect alcohol on your breath or behaviour indicated it. VOSA for issues with the vehicle. Finally customs and excise for red diesel.
I got a short police woman in boots that were almost as big at she was who tried to sniff my breath for alcohol. I twigged quickly what she was doing when she tried to get a bit in my face. So I stood up straight to my 6'5" height so she couldn't get close. I hadn't been drinking for about a month so was clean but I did it out of annoyance. She laughed and said she obviously couldn't smell smell alcohol on my breath and sent me to VOSA. I then bought a new bulb at the next door garage and the VOSA guy put it in, seriously I couldn't get my hand in that gap,, no way at all! Just wouldn't fit! It was not a failed bulb just an extra bright new one so I was a bit annoyed by the stop that technically wasn't justified!
