Light problem

When the friends turn on the headlight during the day, the original tape and the clock on the body turn off, what is the reason?

It is standard in Peugeot. During the night journey, the light intensity decreases so that the light does not take your eyes.
It is a normal situation.

Actually, it must have a setting. The indicators and information display are also adjusted in me, but the tape and air conditioning console do not change and look awkward.
