Often enough that I probably use high visibility lights on several journeys per year on average. It's usually because of dense fog on rural roads but occasionally conditions like torrential rain on a motorway too. On rare occasions I've had to drive in conditions so bad that the front fogs on my car were providing the main or perhaps only useful illumination of the road immediately ahead. We were all just crawling along at barely more than walking pace, even on roads that might normally have been major high-speed routes. Vehicles without appropriate lights were parking up, totally unable to make progress until the weather improved. That definitely hasn't been an annual occurrence in my experience, but it's happened to me more than once. I'd be very wary of buying any new car without excellent lights today. I'd even say the lighting would be in my top 5 deciding factors. Basic headlights have improved dramatically in recent years, thanks to better light sources and adaptive technologies that offer better coverage without dazzling other road users, but the specialised lights like high visibility and reversing lights are also important at the those times when you do need them.
