Moin moin! In the last 2 days I noticed clearly on the way to work: Many people think that the light on their car is only there to see something at night. The last 2 days: heavy cloudy, rain (light to medium strong), view rather beautiful. And? Every 4th to 5th car without light!!! If I had been in the “light duty” discussion rather undecided opinion, I have to say now: LIGHT YES! Because if people do not understand without light duty that you see them in the weather conditions on the country road quite late, then nothing helps. Have you also observed this? LG
