Auto lights sensor

[labsy]

Hi,

Past few months I notice my headlights do not turn on automatically on foggy weather when it's quite dark. Howewer, they turn on at the evening at sunset when it's still quite shiny out there.

Is there any sensor needing cleaning?

Seems like light sensor was a subject of being tried to pull off some time ago, but then whoewer did that, quit. Adhesive gel has some air pockets in it, but it seems did not ply off entirely.
