> 夜、安心して歩けるように街灯を増やして欲しい。

I can sort of understand the meaning of the sentence as someone wants/wishes
that the (number of) street lights to increase so that they can feel safe
walking at night. But I can't understand what grammar rules were used/observed
to form 安心して歩ける

Given the complete sentence above. What is the purpose of having the te-form
of する?

Is it used

  1. as a connector to mean "and" e.g. To have peace of mind and to walk? 

  2. to mean "while" e.g. have peace of mind while walking? 

Maybe there's some grammar construction that I'm missing? Is 歩く even
considered to be a motion verb in the same vein as 行く and 来る?

Sometimes the て form has an adverbial function.
