As part of the Swedish Curriculum (Lp22) as well as teaching the children about " Traffic rules and how to behave in traffic in a safe way" the children also learnt about "Darkness and reflectors". 

It was discussed in the classroom why it is important to wear reflectors when outside in the dark. They also watched a film in Swedish https://urplay.se/program/215487-gatsmart-latt-version-morker-och-reflexer

The class decided to make their own reflective bags with lots of coloured reflective tape on them so that they can be seen outside in the dark when out walking.
