I have had a quick search around, and couldn't find another thread with this, so if I somehow missed it, I apologise for my shoddy searching! This morning, I was driving my W203 C-Class to work (6:30-7:30), and the headlights stayed on for the whole journey. It was quite a bright morning, so it seemed strange to me that the lights stayed on. I know you can set the lights to be permanently on when in auto through the settings, but I am pretty sure I don't have this, as on previous journeys the lights have not been on, but have flicked on in tunnels etc... All I could think of was that the sun was low and mostly behind me, so the sensor may have been in the shade, and so triggered the lights. I have only had the car about a week, so I haven't yet read and learnt everything about it, so maybe I am missing something obvious. I haven't driven it since getting to work, so I don't know for sure if the cause was something related to this particular journey or not. Has anyone else experienced this, or are there any other thoughts on what was going on?
