I don;t drive here but cycle daily. I have a dynamo system built into the front wheel and usually leave my (LED) lights on all the time.
Sometimes, although getting better now the sun gets higher in the sky, if it's bright and I'm wearing my sunglasses it can even be hard to see cars when they're right in the line of the sun. So I'm grateful that drivers here tend to put their lights on when the sun is bright and low in the sky.
I was flashed like crazy one morning by an incoming car as I was coming "from the sun" directly and I guess the lady saw me at the last moment or something and was surprised. She then proceeded to flash be about 6-7 times, the final one being continuous full-beam in my face
ps: 99.9% of the time I use the low-beams, that morning I just forgot for some reason.
My 2010 VW Polo is the opposite. The dash display dims as the outside light goes down and turning the lights on brighten the display, which can be adjusted for brightness too.
Additionally it has daylight running lights (DLR) when the headlights are not on. I have driven with headlights/DLRs on everywhere for the last 20 years. Even in the UK other drivers no longer flash you in daylight to tell you your lights are on.
I read that EU wide 50 lives a year could be saved by all traffic driving with headlights/DRLs. It's a pity the Swiss government copped out and only recommended that light should be used. Not making it law in in Scandinavia...
This is true (although verging towards negligible, imo), but I was more trying to draw a parallel between car lights and domestic lights. We are always being advised to turn off unwanted lights in the home to save power/resources/money, and it wouldn't surprise me if some people didn't think the same with car lights - from what I've seen (not just here) - people driving in the dark/fog with no- or side-lights only.
I have a Volvo. It was only recently that you could turn the lights off. The only times my lights are off are when the engine is off, or the garage has serviced the car. The latter caught me out a few times, as I didn't notice (the dashboard remains lit!) for a while - a nice policeman flagged me down to point out my error. No ticket though - this was in Basel, not Zürich.
I was informed only yesterday from a "supposed knowing source" that they were about to try and pass mandatory daylight running through again... all be it the guys were at a bar and solving the world at the time! LOL
I had these fitted on my old car.. replacing the fog lights with updated ones including DRL - comes on automatically - job done (although no idea if actually legal, there was no comment at last control)
I'm not sure if it's still the case, but there used to be an exception for classic cars (i.e. Veteran MFK).
Most run with the headlights on all the time anyway, even on a 1925 RR which has a genny which isn't powerful enough to run the lights and the ignition without draining the battery.
